Two high-ranking House Republicans announced on Friday that they will be stepping down from their positions as committee chairs, setting off a leadership scramble to fill the powerful vacancies.

Just hours after the passage of the final fiscal 2024 spending bill, Appropriations Committee Chairwoman and retiring Rep. Kay Granger (R-TX) wrote a letter to House Speaker Mike Johnson (R-LA) asking the conference to select a new chairperson “as soon as possible.” Another member who planned to retire at the end of this Congress, Rep. Mike Gallagher (R-WI), announced he would be leaving the chamber and his position as chairman of the House Select Committee on the Chinese Communist Party early in April.
