Which Republicans might back Hegseth impeachment push?

Republican Congressman Thomas Massie is pushing for a House vote to impeach Defense Secretary Pete Hegseth over the Iran war, accusing him of violating the Constitution by continuing military operations without congressional approval. Massie introduced articles of impeachment, citing hostilities in Iran lasting over 90 days without authorization. Republican Representatives Don Bacon and French Hill have expressed concerns, while Senator Thom Tillis has been a vocal critic. House Democratic leader Hakeem Jeffries signaled support, though Massie's effort faces long odds. Hegseth dismissed the threat, saying he is not worried. Massie argues removing him now would prevent Democrats from launching harsher proceedings when they take control of Congress in January. Impeaching a cabinet secretary is rare, with only two such cases in US history.
