A newly released Politico report claims six minority women resigned from Sen. Elizabeth Warren’s Nevada campaign team after complaining about a toxic work environment. The women said they felt like tokens in a competition meant to showcase minorities and were not acknowledged for their ideas.

Three of the women took their complaints to the Warren campaign’s human resource department, but said the situation didn’t change and in some cases only got worse. Megan Lewis, a former Warren field organizer, told Politico she knew there was something wrong with the toxic culture.

“During the time I was employed with Nevada for Warren, there was definitely something wrong with the culture. I filed a complaint with HR, but the follow-up I received left me feeling as though I needed to make myself smaller or change who I was to fit into the office culture,” Lewis said.

On MSNBC, Warren blamed America’s history of racism and oppression for the problems her minority staff members faced.

“I believe these women without any equivocation,” Warren said. “But, I’m also very aware that racism and oppression in this country have left a long legacy and it creates the kind of toxicity where power-structures, people take advantage of other people.”

Warren concluded she takes responsibility for this situation and is working with her team to fix it.
