Sen. Elizabeth Warren, D-Mass., on Wednesday endorsed the bid of Rep. Keith Ellison, D-Minn., to become the next chairman of the Democratic National Committee, adding to the congressman's early momentum in the race to lead the party.
In a statement, Warren praised Ellison's work in Congress "try to hold Wall Street accountable" and praised his leadership as a co-chairman of the Congressional Progressive Caucus.
"I admire Keith's values, his grit, and his dedication to making this country work not just for some of our kids but for all of them," Warren said in a statement.
Meanwhile, former Maryland governor Martin O'Malley took himself out of the running for the post Wednesday after announcing five days ago that he was taking a "hard look" at it.
"While I'm grateful to the friends who have urged me to consider running for DNC Chair, I will not be seeking our Party's Chairmanship," O'Malley said in a statement.
Ellison and O'Malley, who ended a 2016 presidential bid following a poor showing in the Iowa caucuses, are among several people who have publicly expressed interest in the job since Hillary Clinton's stunning defeat to President-elect Donald Trump last week.
Others eyeing the job include former Vermont governor Howard Dean, South Carolina Democratic Party Chairman Jaime Harrison and the DNC's national finance chairman Henry Muñoz III.
The candidacy of Ellison, D-Minn., who supported Sen. Bernie Sanders, Vt., over Clinton in the Democratic primaries, has generated the most buzz.
Warren's support adds to a list of liberal lawmakers, including Sanders, who have coalesced around Ellison. He has also picked up the support of several others in the party's establishment, including outgoing Senate Minority Leader Harry Reid, D-Nev., and Sen. Charles Schumer, D-N.Y., his likely successor.
The next chairman is scheduled to be picked early next year by DNC members across the country, who may or may not take their cue from elected officials. The party's bylaws call for a chairman to be chosen by March 1 to succeed interim chairwoman Donna Brazile, a longtime Democratic operative who stepped in after Rep. Debbie Wasserman Schultz, Fla., announced her resignation in July.
