Sen. Lindsey Graham (R-S.C.), who was a long shot to win the Republican presidential nomination but didn't really seem to mind, announced Monday that he is suspending his campaign.
"I’ve hit a wall here,” Graham told CNN's Kate Bolduan.
Graham, who is known for his hawkish foreign policy views but is more moderate than other Republicans on some issues, entered the campaign on June 1 in his hometown of Central, South Carolina.
