The White House is losing GOP support for the nomination of Paul Ingrassia to a key watchdog post, with at least one Senate Republican vowing to oppose him due to his sympathy for Jan. 6 Capitol rioters.

Sen. Thom Tillis (R-NC) told the Washington Examiner he will vote “no” on Ingrassia, tapped to lead the Office of Special Counsel in May, should his nomination be brought to the Senate floor.
