On August 21, 2026, President Trump held a rally in Myrtle Beach, South Carolina, with Darline Graham ahead of the special primary runoff to fill the Senate seat vacated by her late brother, Lindsey Graham. Trump endorsed Graham, who is facing Rep. Ralph Norman, and urged voters to treat the contest as an extension of his own influence. Graham had failed to secure a majority in the initial primary and stumbled on a foreign policy question in a prior debate.
