Former U.N. Ambassador Nikki Haley notched her first victory of the 2024 primary campaign, besting former President Donald Trump in Washington D.C.

Haley won the contest with nearly 63% of the vote, according to an Associated Press call of the race shortly after polls closed Sunday. The results mean the former South Carolina governor will walk away with 19 delegates.

Washington D.C. represented Haley’s possible best shot at notching a victory and ending Trump’s undefeated primary streak. While Trump won the district in an uncontested 2020 primary, he finished a distant third behind Sen. Marco Rubio of Florida and former Ohio Gov. John Kasich during the 2016 primary. The district also leans heavily towards Democrats, with President Biden garnering 92% of the Washington D.C. vote in the 2020 Election.
