House Homeland Security Committee Chair Mark Green (R-Tenn.) speaks alongside House Speaker Mike Johnson (R-La.)
after the House passed budget reconciliation legislation at the U.S. Capitol on May 22, 2025.
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.
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.
Johnson struggled to coalesce his conference around the megabill, and the narrow majority gave him little wiggle room for defections. »
