The Democrats took back the House with a surge of fresh new candidates and an outpouring of voter enthusiasm Tuesday, breaking the GOP's monopoly on power in Washington and setting the stage for a multitude of investigations of President Donald Trump that could engulf his administration over the next two years.
Ending eight years of Republican control that began with the tea party revolt of 2010, Democrats picked off more than two dozen GOP-held districts in suburbs across the nation on the way to securing the 218 seats needed for a majority.
Democratic Leader Nancy Pelosi, who is seeking to reclaim the gavel as House speaker, called it a "new day in America."
With the Republicans keeping control of the Senate, the outcome in the House could mean gridlock for Trump's agenda on Capitol Hill — or, conversely, it could open a new era of deal-making.
As the majority party, the Democrats will chair important committees and will have expansive powers to investigate the president, his business dealings and the inner workings of his administration, including whether anyone from the Trump campaign colluded with the Russians to influence the 2016 presidential election.
They will have authority to request Trump's tax returns and subpoena power to obtain documents, emails and testimony.
Any attempt to impeach Trump, however, is likely to run headlong into resistance in the GOP-controlled Senate.
9:40 a.m.: Florida Republican Rick Scott declares victory in U.S. Senate race; Bill Nelson wants recount
Democratic Sen. Bill Nelson is requesting a recount in the race for Florida Senate as he trails Republican challenger Rick Scott by a razor-thin margin. Nelson said in as statement Wednesday morning that Scott prematurely declared victory.

7:15 a.m.: Georgia governor's race still going
Georgia's hotly contested and potentially historic governor's race may not be over yet, with Democrat Stacey Abrams and Republican Brian Kemp awaiting the final accounting of absentee and provisional ballots.
With reported votes approaching 3.8 million, Kemp was just shy of 51 percent, but Abrams and her campaign said there were enough ballots outstanding, particularly absentee ballots in heavily Democratic metro Atlanta counties, to bring the Republican below the majority threshold required for victory.
1:29 a.m.: Democrat Tony Evers edges Republican Scott Walker in Wisconsin governor's race
Democrat Tony Evers ousted Wisconsin Gov. Scott Walker on Tuesday, denying the polarizing Republican and one-time presidential candidate a third term and succeeding where his party had failed in three previous attempts, including a 2012 recall.
Evers' victory is a monumental win for Democrats and a steep fall for Walker, who just three years ago was seen as an early front-runner in the GOP primary for president. When Walker dropped out of the presidential race, he focused on rebuilding his low approval ratings in Wisconsin.
Walker had promised if he won the third term would have been his last, but voters decided that two was enough.
1:16 a.m.: Michigan voters bring legal pot to Midwest
Michigan voters on Tuesday made their state the first in the Midwest to legalize recreational marijuana, passing a ballot measure that will allow people 21 or older to buy and use the drug and putting conservative neighboring states on notice.
Three other states had marijuana-related measures on their ballots. North Dakota voters decided recreational pot wasn't for them , while voters in Missouri passed one of three unrelated measures to legalize medical marijuana. Utah voters also were considering whether to allow medical marijuana and to join the 31 other states that have already done so.
Including Michigan, 10 states and the District of Columbia have legalized recreational marijuana. And Canada recently did so. But the passage in Michigan gives it a foothold in Middle America and could cause tension with neighboring Indiana and Ohio, which overwhelmingly rejected a 2015 legalization measure.
12:58 a.m.: Democratic nominee Stacey Abrams says 'votes remain to be counted' in Georgia governor race
Democrat Stacey Abrams says votes remain to be in the tight Georgia governor's race and vows to wait for them all.
Abrams told supporters at her election night party Tuesday that they would "have a chance to do a do-over" in her race against Republican Brian Kemp, implying a runoff.
Kemp has a narrow lead in the vote count, but it was still possible the race could go to a runoff. In Georgia, a race goes to an automatic runoff if neither candidate receives more than 50 percent of the vote.
12:31 a.m.: Republican Rick Scott declares victory in Florida senate race
The Associated Press has not called the race.
Scott declared victory before supporters in Naples. Nelson did not deliver a speech but his campaign conceded just after midnight, despite concerns over ballot counting, the papers reported.

11:53 p.m.: Iowa Republican rep Steve King holds off challenger
Republican Rep. Steve King won a 9th term representing northwest Iowa, defeating Democrat J.D. Scholten.
Voters re-elected King despite a string of controversies about comments and meetings he has held involving other candidates and groups characterized as white nationalists. King has argued that all those he met or made comments about were simply conservatives.
11:49 p.m.: Women elected to House in record numbers
Women will break the current record of 84 serving at the same time in the U.S. House.
With ballots still being counted across the country, women have won 75 seats and are assured of victory in nine districts where women are the only major-party candidates.
From the Women's March opposing President Donald Trump the day after he was inaugurated in January 2017 through a stream of sexual assault accusations later that year that sparked the #MeToo movement, outrage and organizing by women have defined Democratic Party politics this election cycle.
More than 230 women, many of them first-time candidates, were on the general-election ballots in House races.
11:45 p.m.: Beto O'Rourke drops an f-bomb on live TV during concession speech
Rep. Beto O'Rourke didn't go quietly to defeat.
Thanking his campaign supporters for their spirited challenge to Sen. Ted Cruz, he said on live television Tuesday: "All of you, showing the country how you do this. I'm so f---ing proud of you guys."
The Texas Democrat has been known to drop f-bombs in public throughout the fierce campaign. But this time, he was broadcast on MSNBC, prompting anchor Brian Williams to apologize as the network cut away from the speech.
Cruz held off the Democratic rising star to win re-election. O'Rourke attracted a national following, shattered fundraising records and picked up several celebrity endorsements, including Beyonce posting pictures of herself Tuesday on Instagram wearing a Beto baseball cap.
11:40 p.m.: Two Muslim women in U.S. House among historic midterm wins
The House is getting its first two Muslim women and Massachusetts is getting its first black congresswoman while Arizona and Tennessee stand to elect their first woman senators in Tuesday's midterm elections.
The high-profile midterm cycle that produced a record number of women contenders and candidates of color meant several winners will take office as trailblazers, marking firsts for their race and gender.
11:18 p.m.: Democrat Spanberger ousts GOP incumbent Dave Brat in Virginia
Democrat Abigail Spanberger of Virginia was elected to the U.S. House, defeating Republican incumbent Dave Brat.
10:56 p.m.: Republican Bryan Steil easily defeats "Iron Stache" to keep Paul Ryan's House seat red
Wisconsin Democrats thought they finally had a shot at outgoing House Speaker Paul Ryan's 1st Congressional District seat since his decision against seeking re-election after 20 years in Washington.
The party pinned its hopes on Racine ironworker Randy Bryce but Republican attorney Bryan Steil defeated him easily. Bryce had built a national following, branding himself "Iron Stache," a play on his occupation and his thick mustache.
10:51 p.m.: Republican Josh Hawley beats incumbent Democrat Sen. Claire McCaskill in Missouri
Republican challenger Josh Hawley ousted two-term Democratic Sen. Claire McCaskill in a hotly contested race.
Missouri was once considered a bellwether state, but Republicans now control the state Legislature and almost every statewide seat. McCaskill's is one of two statewide offices held by Democrats.
10:35 p.m.: Republican Attorney General Mike DeWine elected Ohio governor
Republican Attorney General Mike DeWine defeated Obama-era consumer protection chief Richard Cordray in the race for Ohio governor on Tuesday, leading a GOP sweep of statewide nonjudicial offices and dashing Democrats' hopes of riding an anti-Trump wave into power in a key swing state.
DeWine, one of the state's most well-known politicians, beat Cordray to succeed term-limited Republican Gov. John Kasich. He was bolstered by strong support across rural Ohio as Cordray did best in the state's urban Democratic strongholds.
10:29 p.m.: Democrat Laura Kelly elected Kansas governor, beating Kris Kobach
Democrat Laura Kelly has defeated a prominent ally of President Donald Trump to win the Kansas governor's race.
Kelly defeated Republican Secretary of State Kris Kobach on Tuesday to flip the governor's office from red to blue.
Kobach had built a national profile as an advocate of tough immigration policies and strict voter photo ID laws. He served as vice chairman of Trump's now-defunct commission on voter fraud.
10:03 p.m.: Republican Ron DeSantis beats Democrat Andrew Gillum in Florida governor race
Ron DeSantis was elected governor of Florida on Tuesday, fueled by the power of President Donald Trump and propelled by the votes of Trump supporters.
By electing DeSantis, Florida voters demonstrated their support for the president, who championed the Republican nominee and repeatedly trashed Democrat Andrew Gillum, who lost.
Gillum conceded just before 11 p.m.
—South Florida Sun-Sentinel
9:48 p.m.: Democrat Sen. Heitkamp falls in North Dakota
Republican Kevin Cramer has ousted North Dakota Democratic Sen. Heidi Heitkamp.
Heitkamp narrowly won her first term in the sharply conservative state. She sought a second by portraying herself as a maverick who wasn't afraid to buck her own party — or President Donald Trump.
She warned that Trump's trade war would damage North Dakota farmers and that Cramer's health care policy would hurt North Dakotans.
But Cramer, a three-term congressman, argued that Heitkamp wasn't the conservative the state needs. He stood strongly with Trump, who remains popular in North Dakota.
A race that was already difficult for Heitkamp appeared to become even harder after she voted against Brett Kavanaugh's nomination to the Supreme Court.
9:32 p.m.: Republican Sen. Ted Cruz holds off Beto O'Rourke in Texas
Republican Sen. Ted Cruz fended off rising-star Democrat Beto O'Rourke to win re-election in a much-watched Texas Senate race that began as a cakewalk but needed a visit from President Donald Trump to help push the incumbent over the top.
Cruz finished a surprising second in the 2016 Republican presidential primary and began the Senate race as a prohibitive favorite.
But O'Rourke visited fiercely conservative parts of the state that his party had long since given up on, while shattering fundraising records despite shunning donations from outside political groups and pollster advice.
9:20 p.m.: Republican Gov. Larry Hogan appears to have fended off Democrat Ben Jealous
Republican Gov. Larry Hogan appeared to win a second term Tuesday, lifted by Democrats who crossed party lines to vote for his centrist approach to governing despite their anger over President Donald Trump.
Tom Perez, chairman of the Democratic National Committee, acknowledged the party’s nominee had lost. “I’m proud of @BenJealous for the incredible race he ran — one focused on issues, progress, and the people of Maryland. Though he came up short, I’m grateful for his commitment to putting our fellow Marylanders first.”
9:17 p.m.: Democrat Whitmer wins Michigan governor race, breaking GOP stranglehold
Democrat Gretchen Whitmer has won the Michigan governor's race to break a Republican power bloc that had been a top target for Democrats.
Whitmer is a former state legislative leader and defeated Republican Attorney General Bill Schuette in Tuesday's election. She will succeed term-limited Republican Gov. Rick Snyder.
Republicans had controlled the governor's office and both chambers of the Michigan Legislature since racking up big victories in the 2010 midterm elections during Democratic President Barack Obama's tenure. The GOP used that trifecta of power to enact congressional and state legislative maps that favored Republicans.
9:15 p.m.: Blackburn becomes first female senator from Tennessee, keeping seat in GOP hands
Republican U.S. Rep. Marsha Blackburn won a grueling, expensive contest Tuesday to become the first female U.S. senator from Tennessee, keeping a key midterm seat under GOP control.
The congresswoman defeated Democratic former Gov. Phil Bredesen by closely aligning her bid with President Donald Trump, who drummed up support for her during three visits to the state that he won by 26 percentage points, including a rally in Chattanooga two days before the election.
Blackburn's win represents a rightward shift from the GOP senator she will replace, Bob Corker, who fell in line with Tennessee's historical preference for more-centrist senators and at times was a vocal critic of Trump.
9:08 p.m.: Florida passes ballot measure to restore felons' voting rights
Potentially altering the election landscape in a key swing state, Florida voters Tuesday approved a ballot measure that will enable more than 1 million ex-felons to regain their voting rights.
Floridians also approved a measure aimed at phasing out greyhound racing in the state, the last stronghold of the sport in the U.S.
Those were the first notable results as voters in 37 states considered an array of intriguing ballot measures — ranging from marijuana legalization to boosting the minimum wage to civil rights protections for transgender people.
9:06 p.m.: Former GOP presidential nominee Mitt Romney wins Utah senate seat
Former Republican presidential candidate Mitt Romney has handily won a U.S. Senate seat in his adopted home state of Utah after a campaign where he backed off his once-fierce criticism of Donald Trump.
Romney clinched the win Tuesday as he defeated Democrat Jenny Wilson, a member of the Salt Lake County council.
Romney was the heavy favorite to win the seat in conservative Utah, where he holds near-celebrity status as the first Mormon presidential nominee from a major party.
He replaces longtime Republican Sen. Orrin Hatch, who chose not to seek re-election.
9:02 p.m.: Democratic Sen. Tammy Baldwin retains Wisconsin seat
Democratic U.S. Sen. Tammy Baldwin has won a second term, fending off a challenge from a Republican who ran as a staunch supporter of President Donald Trump.
Baldwin led Leah Vukmir in fundraising and polls throughout the race.
Baldwin is one of the most liberal members of Congress. The differences between her and Vukmir were stark. They disagreed on almost every issue.
Baldwin made the campaign largely about health care and Vukmir's opposition to the Affordable Care Act. Baldwin argued for keeping the law and its guarantee of insurance coverage for people with pre-existing conditions.
It was Wisconsin's first Senate race where both major party candidates were women.
8:57 p.m.: Democrat Alexandria Ocasio-Cortez wins New York House race
Democrat Alexandria Ocasio-Cortez has defeated a little-known Republican opponent in a district representing part of New York City.
Her victory Tuesday over economics professor Anthony Pappas was widely expected after Ocasio-Cortez scored an unanticipated upset over 10-term U.S. Rep. Joe Crowley in the Democratic primary in June.
At 29 years old, Ocasio-Cortez could become the youngest member of Congress.
She is one of a handful of Congressional candidates who identified as democratic socialists.
Ocasio-Cortez has promised to try and push the Democratic party further to the left.
She supports government-paid health care for all, a $15 minimum wage, free college tuition and the abolition of the federal department of Immigration and Customs Enforcement.
8:35 p.m.: Democrat Joe Manchin retains Senate seat in West Virginia
Democratic Sen. Joe Manchin of West Virginia has turned back a challenge by Republican Patrick Morrisey to win his second full-term in a state carried by President Donald Trump.
Manchin survived the most difficult re-election campaign of his career against the comparative newcomer Morrisey. Manchin is a former governor who has held elected office in West Virginia for the better part of three decades.
Manchin heavily outspent Morrisey and portrayed himself as loyal to his home state rather than party ideology. Manchin was the only Senate Democrat to vote to confirm Supreme Court nominee Brett Kavanaugh.
8:31 p.m.: Republican Mike Braun beats incumbent Democrat Joe Donnelly in Indiana senate race
Republican Mike Braun, a multimillionaire businessman who campaigned as a political outsider, ousted Democratic Sen. Joe Donnelly on Tuesday after a race in which both tried to appeal to Donald Trump supporters.
It's a victory few would have predicted last year when Braun, a two-term state lawmaker, announced he would run in the GOP primary against two congressmen.
But by leveraging his own fortune to loan his campaign more than $10 million, he was able to deluge his Republican rivals under a wave of TV advertisements.
In his concession statement, Donnelly said he was honored to serve the state.
"It has been one of the greatest honors of my life to represent Indiana in the Senate," Donnelly said. "I wish Mike the best, and I hope he makes every single Hoosier proud as our senator."
8:08 p.m.: Republican incumbent rep Andy Barr beats former fighter pilot in Kentucky
Republican U.S. Rep. Andy Barr has won a fourth term in Kentucky's 6th Congressional District.
Barr defeated Democrat and former Marine fighter pilot Amy McGrath on Tuesday. She was considered Barr's toughest challenger since he arrived in Congress in 2012. President Donald Trump won the central Kentucky district by double digits in 2016.
The district includes Lexington and capital Frankfort, and the seat there has switched parties five times since 1978. Both parties saw this race as close. Barr hosted a rally with President Donald Trump, and McGrath campaigned at a high school gym with former Vice President Joe Biden.
8:01 p.m.: Sen. Bob Menendez fends off GOP challenger in New Jersey
New Jersey Democratic Sen. Bob Menendez fended off his wealthy Republican challenger and a barrage of ads about his tossed-out corruption charges to win re-election.
Menendez, 64, wins a third term Tuesday after a grueling campaign against Republican Bob Hugin.
Polls showed Hugin, 64, and Menendez much closer than expected in overwhelmingly Democratic New Jersey.
Hugin tapped his deep pockets for at least $27.5 million and spent on TV ads attacking Menendez over the 2017 trial on charges that he helped a friend with Medicare billing in exchange for lavish gifts.
The charges were dropped this year after a mistrial.
7:40 p.m.: Kentucky clerk who refused to issue gay marriage licenses loses job
The Kentucky clerk who went to jail in 2015 for refusing to issue marriage licenses to same-sex couples has lost her bid for a second term.
Republican incumbent Kim Davis was defeated by Democrat Elwood Caudill Jr. in Tuesday's election for clerk of Rowan County in northeastern Kentucky.
Caudill is well known in the county, having worked for the county Property Valuation Administrator's Office for 21 years. He lost to Davis by just 23 votes in the 2014 Democratic primary. Davis later switched to the GOP.
Davis went from obscure local official to a national figure when she stopped issuing marriage licenses days after the U.S. Supreme Court ruled that the U.S. Constitution guarantees same-sex couples the right to marry. The ruling overturned same-sex marriage bans nationwide. Davis cited her religious beliefs for her action, saying she was acting under "God's authority."
7:37 p.m.: GOP incumbent Comstock falls in Virginia
Republican Rep. Barbara Comstock of Virginia was the first congressional incumbent to lose as voters in her Northern Virginia district expressed their continued dislike of President Donald Trump.
Democratic state Sen. Jennifer Wexton won an easy victory in the wealthy suburban district outside Washington, which Hillary Clinton won by 10 percentage points.
Comstock tried hard to emphasize her independence from Trump, but Wexton, a former prosecutor, portrayed the two-term incumbent as a Trump ally out of touch with the diverse, well-educated district.
7:36 p.m.: Former Clinton Cabinet official flips U.S. House seat in Florida
Donna Shalala has won a U.S. House seat in Florida, making her the first Democrat to flip a GOP seat on Tuesday night.
After serving in President Bill Clinton's Cabinet as Health and Human Services Secretary and running major universities, Shalala is starting a third career with her election to the House.
The 77-year-old Democrat won Tuesday in a Miami district that had long been in Republican hands over former television journalist Maria Elvira Salazar. The district was represented for decades by GOP Rep. Ileana Ros-Lehtinen, who is retiring.
7:30 p.m.: Elizabeth Warren among group of early Democratic Senate winners
Sen. Elizabeth Warren of Massachusetts, a potential 2020 White House contender, is among a group of six Democratic lawmakers who have easily won re-election to the Senate.
Sens. Sherrod Brown of Ohio, Chris Murphy of Connecticut, Ben Cardin of Maryland, Tom Carper of Delaware and Sheldon Whitehouse of Rhode Island also won. They were heavy favorites in their races.
7:14 p.m.: Indiana approves amendment for balanced budget
Voters have approved an amendment to the Indiana Constitution obligating the General Assembly to adopt balanced budgets unless two-thirds of the members of both chambers vote to suspend the requirement.
The amendment twice cleared the General Assembly after Vice President Mike Pence first proposed it in the 2015 State of the State address when he was Indiana's governor.
Republican Rep. Todd Huston of Fishers sponsored the resolution in the Indiana House. He said the amendment forces lawmakers to fund pension responsibilities and bonding responsibilities.
The constitution already largely banned the state from incurring debt, except in times of war. Under the amendment, the General Assembly would be required to pass a balanced budget unless supermajorities vote to suspend the rule.
6:59 p.m.: Tim Kaine defeats Corey Stewart in Virginia senate race
Democrat Tim Kaine, Hillary Clinton's running mate in the 2016 presidential election, retained his Senate seat on Tuesday, defeating Republican Corey Stewart.
Stewart, a die-hard Trump supporter, is a conservative provocateur best known for his outspoken support of Confederate imagery and hard-line views on immigration. He struggled to raise money and was ignored by national GOP groups.
6:23 p.m.: Voters, including governor candidate, face malfunctions, long lines in closely watched Georgia race
Widespread reports of technical malfunctions and long lines at polling stations came in from across Georgia, with some voters reporting waits of up to three hours to cast ballots.
Republican Brian Kemp and Democrat Stacey Abrams are competing for governor in one of the signature contests of the 2018 midterm elections.
Kemp, the state's elections chief wasn't immune to the issues: When he went to cast his ballot, he had an issue with his voter card, but it was fixed quickly. He walked by reporters and said: "Take Two."
Abrams, a 44-year-old Atlanta attorney, former lawmaker and moonlighting romance novelist would be the first black woman in American history elected governor in any state and the first woman or nonwhite governor in Georgia history.
Kemp, a 54-year-old businessman and veteran secretary of state is vying to maintain the GOP's hold on a state that is nearing presidential battleground status courtesy of its growth and diversity.
6:10 p.m.: Bernie Sanders re-elected to Senate
Independent Sen. Bernie Sanders defended his Vermont seat on Tuesday, beating Republican Lawrence Zupan.
Sanders easily won his third term in the Senate, outpacing Zupan and seven other candidates.
6:00 p.m.: Guam elects territory's first female governor
Former Democratic lawmaker and current Bank of Guam President Lou Leon Guerrero has been elected the first female governor of the U.S. territory.
"We are extremely grateful for the opportunity given to us to make a positive change for all our people," Leon Guerrero said, according to Pacific Daily News.
With all 67 precincts counted, Leon Guerrero and Joshua Tenorio, her running mate, received 50.7 percent of the votes cast for governor of Guam, defeating incumbent Republican Lt. Gov. Ray Tenorio and Tony Ada, who received 26.4 percent of the vote. Leon Guerrero won by more than 8,600 votes.
The margin is large enough to avoid a runoff, according to final unofficial results released at 7 a.m. Wednesday.
Leon Guerrero will be the ninth elected governor of Guam and will be limited to two four-year terms.
Guam is about 4,000 miles west of Hawaii, with a population of more than 160,000 people.
5:05 p.m.: First polls close in Indiana, Kentucky
Polls closed in eastern Kentucky and parts of Indiana as the nation votes in the first midterm elections of Donald Trump's presidency.
4:15 p.m.: Trump, health care, immigration high on voters' minds
Health care and immigration were high on voters' minds as they cast ballots in the midterm elections, according to a wide-ranging survey of the American electorate conducted by The Associated Press.
Twenty six percent named health care as the most important issue facing the country, followed by 23 percent who cited immigration.
AP VoteCast also shows nearly two-thirds of voters said Trump was a reason for their vote, while about a third said he was not.
A majority of voters overall say the country is headed in the wrong direction. Still, about two-thirds say economic conditions are good.
In all, the survey included interviews with more than 113,000 voters nationwide.
2:50 p.m.: Homeland Security Secretary Kirstjen Nielsen says U.S. ready for cybersecurity trouble
Homeland Security Secretary Kirstjen Nielsen says cybersecurity officials are hoping for the best in the midterm election but preparing to react to the worst.
Nielsen says that the election will be the most secure in the modern era. She was speaking Tuesday at a command center where state and local officials are working with federal agents to share information on possible interference from foreign or domestic agents.
States run elections, but Homeland Security is the federal department tasked with both cybersecurity and protecting the country's election infrastructure.
Voters were managing long lines and malfunctioning machines, but those problems weren't because of any foreign interference.
Nielsen says no voting machines have been compromised, but there has been a misinformation effort by foreign groups eager to sow discord.
1:55 p.m.: For voters, Election Day presents a big test for Trumpism
There were first-time voters and straight-ticket voters and some who, this go-around, switched sides. They went to the polls considering the caravan of migrants trudging across Mexico, their health insurance and their paychecks, an impotent Congress and the nation's poisonous political culture that has divided even families and friends along party lines.
More than anything on this Election Day in America, in a midterm contest like no other before it, voters cast their ballots with one man in mind: President Donald Trump.
12:57 p.m.: Voters face long lines, machine snafus, 'mosh pit' crowds
Long lines and malfunctioning machines marred the first hours of voting in some precincts across the country today. Some of the biggest problems were in Georgia, a state with a hotly contested gubernatorial election, where some voters reported waiting up to three hours to vote.
Across the United States, even before today's vote, there were a wide variety of concerns with voting and registration systems around the country — from machines that changed voter selections to registration forms tossed out because of clerical errors.
Election officials and voting rights groups have feared that voter confidence in the results could be undermined if such problems become more widespread on Election Day, as millions of Americans decide pivotal races for Congress and governor.
12:18 p.m.: President Trump to spend Election Day out of public eye
President Donald Trump's usually active Twitter feed was quiet for most of the morning as voting booths opened across the country. He returned to the White House after headlining final campaign rallies in Ohio, Indiana and Missouri, and planned to spend Election Day at the White House all but out of public view.
He and first lady Melania Trump voted in New York via absentee ballot several weeks ago, the White House said.
Press secretary Sarah Huckabee Sanders said Trump would spend the day making telephone calls, monitoring congressional and gubernatorial races and meeting with his political team. In the evening, family and friends were joining Trump and first lady in the White House residence to watch the election returns.
Trump broke his Twitter silence mid-day, tweeting a link to votegop.com before praising U.S. Senate candidate Bob Hugin.
10:50 a.m.: Pelosi says midterm elections are 'about health care'
House Democratic leader Nancy Pelosi says the midterm elections are basically a referendum on Republican efforts to scrap Obamacare.
The California Democrat says at a morning press conference that the election is "about health care."
Pelosi credits Democratic politicians and activists across the country with helping to fend off attempts to repeal the Affordable Care Act following 2016 election results that left Republicans in control of Congress and the White House.
Pelosi says that after 2016 Democrats "didn't agonize, we organized."
She forecasts Democratic victories across the country, but with a small overall margin of victory. Pelosi says that as few as 25,000 votes nationwide could swing the results.
Pelosi has remained noncommittal amid speculation that she would step aside to make way for new leadership, regardless of the election results.
10:41 a.m.: Migrants camp at Mexico City stadium as U.S. votes
Thousands of Central Americans dreaming of getting to the United States awoke this morning to donations of fruit and hot coffee at a sports stadium in Mexico's chilly capital as the U.S. held midterm elections in which President Donald Trump has made the migrant caravan a central issue.
Authorities counted more than 2,000 migrants at the Jesus Martinez stadium late yesterday, and a steady flow continued into the night.
Trump has seized on the caravan and portrayed it as a major threat, though such caravans have sprung up regularly over the years and largely passed unnoticed. He ordered thousands of troops to the Mexico-U.S. border, threatened to detain asylum seekers and insinuated without proof that there are criminals or even terrorists in the group.
10:25 a.m.: Moscow hopes U.S. election will ease tensions
Russia's Foreign Minister Sergey Lavrov says he hopes the outcome of the U.S. midterm election will ease domestic tensions in the United States and enable Washington to focus on global issues.
Speaking to reporters in Madrid, Lavrov lamented that Russian-American ties have become "hostage to internal political squabbles in America."
Lavrov said he is hopeful that the election will help stabilize domestic politics in the U.S. "so that Washington could concentrate on some positive steps on the international arena."
Lavrov also reiterated Moscow's position that it is not meddling in U.S. elections.
He said, "All the accusations that we will be meddling in today's elections turned out to be empty statements."
9:01 a.m.: Election Day storms, wind could affect turnout
Severe weather in several Southern states could affect voter turnout on Election Day.
A line of storms moved through the Deep South overnight and early this morning, knocking down trees and power lines from Louisiana to South Carolina. There were no serious injuries but an estimated 11,000 residents were left without electricity.
A separate storm front in central Tennessee overnight killed one person, injured two others and also left thousands without power.
The National Weather Service warned of a possibility of high winds, severe thunderstorms and possible tornadoes today around Baltimore, Washington, D.C., and the Mid-Atlantic region.
Dry weather was forecast for the West and Southwest, but significant snow accumulations were expected across the northern Rockies.
7:39 a.m.: Facebook blocks 115 accounts ahead of elections
Facebook said it blocked 115 accounts for suspected "coordinated inauthentic behavior" linked to foreign groups attempting to interfere in today's U.S. midterm elections.
The social media company shut down 30 Facebook accounts and 85 Instagram accounts and is investigating them in more detail, it said in a blog post late yesterday.
The company took action after being tipped off Sunday evening by U.S. law enforcement officials, who notified the company about recently discovered online activity, "which they believe may be linked to foreign entities," Facebook's head of cybersecurity policy, Nathaniel Gleicher, wrote in the post .
