Ohio GOP Rep. Bill Johnson will resign from Congress on Jan. 21 to become the new head of Youngstown State University, a move that will further shrink the tight House GOP majority.

Johnson’s departure, coming on the heels of the resignation of Rep. Kevin McCarthy (R-Calif.) and the expulsion of Rep. George Santos (R-N.Y.), means Republicans will control just 219 seats. Once he leaves, the GOP can only lose two members of their conference for a vote to pass.
