Democratic Michigan Rep. Rashida Tlaib incited a crowd at a campaign event for Independent Vermont Senator Bernie Sanders to boo Hillary Clinton Friday night.

Tlaib was in Clive, Iowa assisting Sanders’ Democratic presidential campaign as a participant on a panel discussion with Democratic Minnesota Rep. Ilhan Omar and Democratic Washington Rep. Pramila Jayapal, The Hill reported.

Tlaib decided to voice her discontent over the former secretary of state who has become increasingly critical of Sanders and his presidential candidacy.

Activist Dionna Langford reminded the crowed that Clinton has continued to snipe at Sanders, recently saying that “nobody likes him.” That comment provoked boos from the audience. Langford attempted to calm the group down by saying, “We’re not gonna boo, we’re not gonna boo. We’re classy here.” (RELATED: Democrats Who Want To Stop Bernie Are Worried That He Could Be There Party’s Trump)

But Tlaib seemingly did not agree as she egged on Sanders’ supporters: “I’ll boo. Boo.”

“You all know I can’t be quiet,” Tlaib added. “The haters will shut up on Monday when we win.”

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