Sen. Lindsey Graham (R-S.C) has won re-election against Democrat Jaime Harrison in a highly competitive and closely watched race for the U.S. Senate, AP projects.

Graham is chairman of the Senate Judiciary Committee and led the controversial push to confirm Supreme Court Justice Amy Coney Barrett a week before the election.
