The two agreed that if they ultimately faced each other as presidential candidates, they should remain civil and avoid attacking one another, so as not to hurt the progressive movement. They also discussed how to best take on President Donald Trump, and Warren laid out two main reasons she believed she would be a strong candidate: She could make a robust argument about the economy and earn broad support from female voters.
Sanders responded that he did not believe a woman could win.
That evening, Sanders expressed frustration at what he saw as a growing focus among Democrats on identity politics, according to one of the people familiar with the conversation. Warren told Sanders she disagreed with his assessment that a woman could not win, three of the four sources said.
Sanders denied the characterization of the meeting in a statement to CNN.
"It is ludicrous to believe that at the same meeting where Elizabeth Warren told me she was going to run for president, I would tell her that a woman couldn't win," Sanders said. "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."
