The GOP majority in the House is about to shrink even further with Rep. Mike Gallagher’s (R-WI) sudden decision to resign from Congress.

In an announcement on Friday, Gallagher revealed that he has decided against his initial plan to not seek reelection when his term ends and will now be leaving next month.

“After conversations with my family, I have made the decision to resign my position as a member of the House of Representatives for Wisconsin’s Eighth Congressional District effective April 19, 2024. I’ve worked closely with House Republican leadership on this timeline and look forward to seeing Speaker Johnson appoint a new chair to carry out the important mission of the Select Committee on the Chinese Communist Party,” he wrote.

“My office will continue to operate and provide constituent services to the Eighth District for the remainder of the term. Four terms serving Northeast Wisconsin in Congress has been the honor of a lifetime and strengthened my conviction that America is the greatest country in the history of the world,” the statement read further.

Gallagher’s planned resignation from Congress follows recent exits by House Republicans, the latest being Rep. Ken Buck (R-OH).

With his departure now, Gallagher would be reducing the Republican majority in the House to 217-213, giving the party just one single defection in order to maintain its majority when voting. As little as two defections would mean a 215-215 tally.

The Wisconsin lawmaker did not reveal his plans for the future. However, there are reports that he will be taking up a job at defense contractor Palantir, a company that specializes in surveillance and data management.
