President Trump on Sunday formally endorsed Sen. Lindsey Graham (R-S.C.), one of his closest allies on Capitol Hill, ahead of the South Carolina primary.
Trump urged voters in a tweet to back Graham in his Senate primary race set to take place on Tuesday.
“Senator @LindseyGrahamSC is a good friend and strong voice for the people of South Carolina,” Trump posted. “He’s helped us confirm GREAT Judges, rebuild the Military, and keep our Country SAFE. Strong on Life and our Vets. Lindsey has my Complete and Total Endorsement!”
The president included a link to the Graham campaign’s donation website.
The South Carolina Republican has been a vocal supporter of Trump throughout his administration, which has further inspired the state’s Democratic movement to unseat him.
Graham will run against three other Republicans in the primary. But his biggest challenge is expected when he faces likely Democratic nominee Jaime Harrison, the former chairman of the South Carolina Democratic Party, in the general election.
The state primaries for Georgia, Nevada, North Dakota and West Virginia and the presidential primaries for Georgia and West Virginia are also scheduled for Tuesday.
