Trump projected to win South Carolina Republican primary
The Associated Press, ABC News, NBC News and Fox News made the projection just a few minutes after polls closed in the southeastern US state on Saturday at 7 p.m. local time, Xinhua news agency reported.
The defeat delivered a crushing blow to Haley, who was born in the state and served as its governor from 2011 to 2017.
A growing number of Republican figures have urged Haley to drop out so that they could focus on the fight against the Democratic Party.
In a speech earlier this week, Haley vowed to continue her 2024 presidential campaign beyond Saturday's contest.
