Molly Prince of the Daily Caller details allegations that could hurt any attempt from Vermont Sen. Bernie Sanders to repeat his 2016 presidential run.

As Independent Sen. Bernie Sanders gears up for a potential 2020 presidential run, allegations regarding the mistreatment of women on his 2016 campaign may hinder his chances at the White House.

Former staffers on the Sanders campaign have been detailing instances of sexism and sexual harassment while working on his presidential bid in 2016, according to a New York Times report published Wednesday.

After a letter circulated in December referring to a “dangerous dynamic” between the men and women on Sanders’ 2016 presidential campaign, claims of rampant “sexual violence and harassment” have been on the forefront of discussions among former Sanders supporters.

The letter, which was signed by more than two dozen women, requested to sit down with the Vermont senator and his closest advisers to discuss the issue at hand.

The Sanders campaign has also been hit with accusations of sexism stemming from the pay disparity between genders. Salary records reportedly show that male staffers earned thousands of dollars more than female staffers for the same jobs.

“Was it too male? Yes. Was it too white? Yes. Would this be a priority to remedy on any future campaign? Definitely, and we share deeply in the urgency for all of us to make change,” Jeff Weaver, Sanders’ campaign manager, told The NYT.
