After dropping out of the race on Thursday, Sen. Elizabeth Warren declined to formally endorse any of the other candidates left in the Democratic presidential primary.
Warren said Thursday that she would ultimately endorse a candidate, but "not today."
"Let's take a deep breath and spend a little time on that," Warren said, speaking outside her home in Cambridge, Massachusetts. "We don't have to decide that this minute."
The Massachusetts senator has reportedly received calls from both Joe Biden and Bernie Sanders, who are both still in the running for the Democratic nomination, although it is unclear if either candidate asked Warren for her endorsement.
