Republican Rep. Thomas Massie introduced a measure to impeach Defense Secretary Pete Hegseth on Monday, roughly one week after the unpopular Iran war the Pentagon chief championed fueled a midterm defeat for President Donald Trump’s Republican Party.

Massie launched his new bid to oust Hegseth as the House of Representatives resumed work following the midterm elections. He posted his resolution outlining charges against Trump’s defense secretary on social media earlier in the day, and introducing the measure on Monday sets up a floor vote on the motion as soon as Wednesday.

“The reality is, we’re not indicting him for being bad at his job. In fact, he was very effective at killing school children in Iran,” Massie told reporters Monday. “He was very effective at extrajudicial killings. There’s no argument in these impeachment articles that he’s ineffective. The argument here is that he’s broken laws, and he’s violated the Constitution. And so, that’s the question put in front of my colleagues.”
