Thune says he won’t endorse ‘at the moment’ in South Carolina Senate race

Senate Majority Leader John Thune (R-S.D.) told reporters he won't endorse a primary candidate to replace the late Sen. Lindsey Graham (R-S.C.) for a full term. "I'm not endorsing at the moment," Thune said. Graham's sister, Darline Graham, was sworn in to temporarily fill the seat.
