Rep. Thomas Massie (R-KY) on Wednesday appeared to threaten to pursue the impeachment of President Biden if he started a war with Iran.

Massie posted a video from 2007 on X of then-Senator Biden threatening President George W. Bush with impeachment if he went to war with Iran without congressional approval.

“I made it clear to the president that if he takes this nation to war in Iran without congressional approval, I will make it my business to impeach him,” Biden said in the video.

In his post, Massie wrote: “In 2007, Sen. Biden put the President on notice that he would impeach him for going to war with Iran without Congressional approval. Consider this your notice [President Biden].”
