Sen. Lindsey Graham (R-S.C.) said today that he is suspending his campaign for president.
His announcement, in a video posted to his campaign website Monday morning, comes a day before the filing deadline for the South Carolina presidential primary ballot.
Graham, who has been one of the lowest-polling GOP candidates, said his campaign goal was to bring national security to the forefront of the Republican field.
“I got in this race to put forward a plan to win a war we cannot afford to lose and to turn back the tide of isolationism that was rising in our party,” Graham said in today’s video. “I believe we have made enormous progress in this effort.”
The race for the Republican nomination now has 13 candidates.
