Rep. Rashida Tlaib (D-Mich.) booed Hillary Clinton s name Friday during a live campaign event for Sen. Bernie Sanders (I-Vt.) in Iowa.

Haters will shut up on Monday when we win, she added.

She booed Clinton during a panel discussion that also included Reps. Ilhan Omar (D-Minn.) and Pramila Jayapal (D-Wash.) at a Sanders Caucus Concert ahead of the Iowa contest, the first of the primary season.

The moderator, Iowa activist and former school board member Dionna Langford , noted that Clinton recently claimed that nobody likes Sanders, which drew boos from the audience. Langford cautioned: Were not gonna boo. Were classy here.

Thats when Tlaib booed.

You all know I cant be quiet, she added. The haters will shut up on Monday when we win.

Tlaib infamously said of President Donald Trump shortly after her own election, impeach the motherfucker.

Clinton complained in a podcast interview Friday that Sanders didnt do enough to unite the Democratic Party after he lost the 2016 primary and that it affected the general election.

All the way up until the end, a lot of people highly identified with his campaign were urging people to vote third party, urging people not to vote, Clinton said in an interview with Emily Tisch Sussman on her podcast Your Primary Playlist . It had an impact.

Rashida was trending on Twitter Friday night. Reactions were mixed.
