"I want to start with the news. I want all of you to hear it first, and I want you to hear it straight from me: Today, I’m suspending our campaign for president," Warren said, according to a transcript of a call she had with her staffers that was published by the campaign on Medium.
Warren picked up 65 delegates throughout the Democratic primary process, but she trails frontrunners Joe Biden (596) and Sen. Bernie Sanders (531) by hundreds of delegates.
Warren told reporters in a press conference at her home Thursday that she will "take some time" before she makes an endorsement.
Warren also told reporters that when she entered the race, she believed there was more room in the race for the Democratic nomination for a candidate outside of the "moderate lane" and the "progressive lane."
"It turns out, that wasn't the case," Warren said.
On top of a likely insurmountable lead, Warren finished in a disappointing third place in her home state of Massachusetts on Tuesday.
Warren's deicision comes after she announced on Wednesday she would reasses her campaign. She's the second candidate to drop out following Super Tuesday, following in the footsteps of Mike Bloomberg. She's the fourth candidate to drop out following Saturday's South Carolina primary — Pete Buttigieg and Sen. Amy Klobuchar (D-Minnesota) ended their campaigns over the weekend.
Biden, Sanders and Rep. Tulsi Gabbard (D-Hawaii) are the only candidates remaining for the Democratic presidential nomination. Gabbard has picked up one pledged delegate throughout the primary process.
