Sen. Elizabeth Warren “came to raise a concern” with Sen. Bernie Sanders after Tuesday's Democratic presidential debate, according to the Sanders campaign. At the end of the debate, Warren and Sanders appeared to exchange some terse words. Sanders briefly offered his hand to Warren as she approached him, only to seemingly be rebuffed. CNN didn’t pick up the sound of their conversation, but the two seemed to be engaged in a rather tense back-and-forth, all while billionaire presidential hopeful Tom Steyer awkwardly stood by and watched. Sanders’s campaign manager Faiz Shakir later told The Washington Post: “She came to raise a concern, and he said let's talk about that later.” Tuesday night’s debate came on the heels of Warren confirming reports that the Vermont senator told her in December 2018 in a private meeting that a woman couldn’t win the upcoming presidential election, a claim Sanders has denied.
