Democratic presidential candidate Hillary Clinton will call for new gun control measures on Monday, including the use of executive action to tighten loopholes if Congress won't act, a campaign aide said.
Outlining her ideas just days after the mass shooting at an Oregon college, Clinton is set to use appearances in New Hampshire on Monday to say that her administration would press lawmakers to pass background check legislation and to repeal a 2005 law that prevents gun manufacturers and dealers from being sued for crimes perpetrated with their guns.
If Congress does not act, Clinton is expected to say she would use executive action as president to require dealers selling a significant number of weapons to be considered "in the business," a designation that would require background checks for those sellers.
"This would ensure that high-volume gun sellers are covered by the same common sense rules that apply to gun stores -- including requiring background checks on gun sales," an aide said.
Dan Gross, president of the Brady Campaign to Prevent Gun Violence, praised Clinton for the plan on Monday.
"Just four years ago it seemed unthinkable that a major presidential candidate would make gun violence prevention a cornerstone of his or her platform," Gross said. "This is a major victory for the 90 percent of Americans who support expanding Brady background checks to all gun sales and is further evidence that we are at a tipping point on this issue."
Both Clinton and former Maryland Gov. Martin O'Malley have sought to distinguish themselves on the issue from Vermont Sen. Bernie Sanders, who voted against the 1993 Brady Bill that established background checks. O'Malley used a speech in New Hampshire on Sunday to call on Clinton to release a more specific gun control plan.
Maryland was one of the first states to respond to the Sandy Hook Elementary School shooting in 2012, passing a law that lowered magazine capacity and increased state regulations for gun dealers.
"We had to take on people in our own party who had some cultural affinities with North Carolina that were closer than their affinities with North Baltimore," O'Malley said, according to a transcript of his speech provided by his campaign. "But we did it. We never gave up."
