Some might call her a nasty woman.

Michigan Rep. Rashida Tlaib took a moment to voice her personal displeasure with Hillary Clinton, loudly booing the former Secretary of State and 2016 presidential candidate during an event in Iowa Friday.

“You all know I can’t be quiet,” Tlaib told audience members during a campaign rally for Bernie Sanders in Clive, Iowa. “The haters will shut up on Monday when we win.”

Tlaib was joined onstage by House colleagues Washington state Rep. Pramila Jayapal and Minnesota Rep. Ilhan Omar — both of whom could not contain their laughter at Tlaib’s comments. The three congresswomen are part of a handful of progressive lawmakers in Congress who are backing Sanders’ bid for the nomination.

Tlaib walked back the remarks just hours later.

“I allowed my disappointment with Secretary Clinton’s latest comments about Senator Sanders and his supporters get the best of me. You all, my sisters-in-service on stage, and our movement deserve better,” she said on Twitter.

After an October heart attack left many believing his candidacy was DOA, the 78-year-old Vermont socialist has rocketed to the top of the polls in Iowa and New Hampshire. The good news comes despite Sanders skipping out on late campaigning in the early states to fulfill his responsibilities as a juror in President Trump’s Senate impeachment trial

The Iowa caucus will officially kick off Monday.
