What happens next after Kevin McCarthy ousted as speaker of the House
Excerpt:
Separately in January, McCarthy also appointed members to act as speaker pro tempore to sign enrolled bills. These names were made public in the Congressional Record, offering a look at who McCarthy trusts in his absence. But it is important to note, this is not the list that would be consulted in the case of a vacancy.
McCarthy chose Reps. Patrick McHenry and Richard Hudson of North Carolina; Rep. Adrian Smith, of Nebraska; Rep. Robert Wittman, of Virginia; Rep. Andy Harris, of Maryland; and Reps. John Joyce and Guy Reschenthaler, of Pennsylvania to act as Speaker.

Andy Harris is a conservative fighter. Only R from Maryland in seems like forever.
