Sen. Elizabeth Warren (D., Mass.) held out on endorsing Hillary Clinton or Sen. Bernie Sanders (I., Vt.) for the Democratic nomination for president Monday, telling reporters that she is unsure when she will announce who will win her endorsement.
"No endorsements now," Warren said in Springfield, Massachusetts, according to MassLive.com. She added that she believes the Democratic candidates are doing a "terrific" job and "talking about the issues."
Warren made her comments just as Clinton, Sanders, and former Maryland Gov. Martin O’Malley met in the Iowa Democratic caucus Monday night. The first early voting state offered a tight battle between Clinton and Sanders, who were separated by less than a percentage point in the polls.
Clinton claimed victory over Sanders early Tuesday, but it wasn’t until that afternoon that the Associated Press declared Clinton the winner with a 0.2 percentage point lead. O’Malley suspended his campaign with about a quarter of the votes still uncounted Monday night when he was polling at under 1 percent.
Warren would not rule out that her endorsement could come soon, indicating that she could announce her support following the Iowa caucus.
Warren has in the past expressed criticism of Clinton for her ties to Wall Street. Sanders has seized on similar critiques when challenging the former secretary of state for the Democratic nomination. The Massachusetts senator would not say Monday whether she intends to support Sanders over Clinton.
When pressed on her concerns about Clinton’s financial industry connections, Warren said that she has "concerns about everybody’s relationships with Wall Street."
"This is a rigged game and it’s rigged because Wall Street makes sure that in every decision that gets made they’re there," Warren said. "They make sure they’ve got their lobbyists and their lawyers so that everything tilts just a little bit more their direction. This is what I’m fighting everyday in the United States Senate."
Clinton has received about $2.5 million in campaign contributions from Wall Street, according to OpenSecrets.
Clinton held a private meeting with Warren in December 2014 as she was preparing to launch a presidential run, soliciting policy ideas and advice from the progressive senator. Still, Warren has so far refrained from endorsing Clinton.
