Rep. Shri Thanedar, a Michigan Democrat facing a contested primary next year, made a splash Tuesday by forcing a House vote on articles of impeachment for President Donald Trump.

And some of his colleagues are furious about it.

The vote, scheduled for Thursday, has almost no chance of success. Instead, House Democrats privately told Axios, Thanedar’s decision will only endanger Democrats in competitive districts.

“This is the dumbest fucking thing. Utterly selfish behavior,” one House Democrat told the outlet.

Another said of Thanedar, “What a dumbshit.”
