President Donald Trump is scheduled to travel to South Carolina on Friday to campaign for Sen. Darline Graham. Graham, a political novice, is seeking a six-year U.S. Senate term to replace her late brother, Sen. Lindsey Graham.
The visit comes as a last-minute appeal ahead of a Republican runoff next week, where Graham is facing Rep. Ralph Norman to replace her brother on the ballot in November.
The trip serves as a test of the president's political clout in a heavily Republican state. This endorsement arrives as Trump's influence is under scrutiny following the recent losses of several other candidates he supported.
