Sen. Elizabeth Warren said in a statement on Monday that fellow presidential hopeful Sen. Bernie Sanders told her in a private meeting in 2018 that a woman could not win the White House.

“Bernie and I met for more than two hours in December 2018 to discuss the 2020 election, our past work together and our shared goals: beating Donald Trump, taking back our government from the wealthy and well-connected, and building an economy that works for everyone,” Warren said in a statement. “Among the topics that came up was what would happen if Democrats nominated a female candidate. I thought a woman could win; he disagreed.”

Sanders blasted the report, and his allies were furious, describing it as a desperate effort by Warren staffers and the mainstream media to blunt his momentum ahead of the Iowa caucuses.

“It’s sad that, three weeks before the Iowa caucus and a year after that private conversation, staff who weren’t in the room are lying about what happened. What I did say that night was that Donald Trump is a sexist, a racist and a liar who would weaponize whatever he could. Do I believe a woman can win in 2020? Of course! After all, Hillary Clinton beat Donald Trump by 3 million votes in 2016.”
