Rep. Mark Green resigns from Congress, leaving Speaker Johnson with an even narrower Republican majority in the House

Rep. Mark Green, R-Tenn., announced his official resignation from Congress on Friday, a move that was expected but one that could, at least for now, shrink Republicans’ already narrow majority in the House.

“To my constituents across Tennessee’s 7th District—thank you. The trust you put in me is humbling. I will look back fondly on my years of serving as your voice in Washington,” Green wrote in a post on X.

With his resignation, Republicans are down to a 219-212 majority in the House, at least until his seat in the solidly red district is filled.

His resignation will be effective July 20, Fox News reports from a letter Green sent to House Republican leadership.

Green’s resignation is a blow to House Speaker Mike Johnson’s already narrow majority in the lower chamber, a fact that was on stark display this week as he was trying to pass President Donald Trump’s “big, beautiful bill.”
