March 3 (UPI) -- Nikki Haley, the former governor of South Carolina, has won the District of Colombia's Republican primary, securing her first victory over front-runner Donald Trump and making her the first woman to win a GOP primary race.
Nineteen delegates were up for grabs in the district Sunday night. The Republican Party of Washington, D.C., said Haley, who is also the former U.S. ambassador to the United Nations, secured nearly 63% of the vote.
