Sen. Elizabeth Warren’s (D-MA) presidential campaign finance director resigned over her insistence that she would not hold high-dollar fundraisers, CNN and The New York Times reported Sunday.

Warren first announced in late February that “my presidential primary campaign will be run on the principle of equal access for anybody who joins it. That means no fancy receptions or big money fundraisers only with people who can write the big checks.”

The Times reported that Warren made that decision “only after a robust debate inside her campaign that led to the resignation of her finance director, Michael Pratt, who strenuously objected to the idea.”

That debate occurred on Valentine’s Day, per the Times. The paper reported, citing unnamed Democrats briefed on the conversation, that Pratt urged Warren to consider the campaign cash high-dollar donors could provide, as well as their powerful networks.

“But Mr. Pratt lost the argument to two of Ms. Warren’s closest advisers, Dan Geldon and Joe Rospars, who made the case about standing apart from the field and freeing up her schedule,” the Times reported.

CNN reported that Pratt’s decision to leave the campaign was a “recent” one.

An unnamed Warren campaign aide told the network that Pratt was “still a consultant but winding things down and transitioning out since we made the decision not to have (Warren) do high dollar events.”
