Republican presidential candidate Nikki Haley defeated former President Donald Trump in Sunday's Washington, D.C. primary.
Haley defeated Trump by nearly 30 points last night, marking her first primary win this election season.
However, Haley faces an uphill battle against the former president as Trump has secured 247 of the 1,215 delegates required for the Republican nomination.
Haley commented on her Sunday win in an X post.
"Republicans closest to Washington's dysfunction know that Donald Trump has brought nothing but chaos and division for the past 8 years," she wrote. "It's time to start winning again and move our nation forward!"
Earlier Sunday, Haley indicated she may not abide by her pledge with the Republican National Committee (RNC) to support the eventual nominee.
"I think I’ll make what decision I want to make,” Haley said.
Critics of Haley noted her Washington win was indicative of their aversion to her candidacy.
"The only GOP primary Nikki Haley will win is Washington, D.C.," wrote podcaster Benny Johnson. "If that doesn't tell you everything you need to know, then I don't know what does."
"Finally the deep state won one," wrote Zerohedge.
"Any questions on if the Swamp supports her or not, you have your answer," wrote journalist and political strategist Matt Couch. "It's the only place she can win."
Trump, who has dominated state primaries this election season, commented on Haley's Washington win in a Truth Social post.
"I purposely stayed away from the D.C. Vote because it is the 'Swamp,' with very few delegates, and no upside," he wrote. "Birdbrain spent all of her time, money and effort there. Over the weekend we won Missouri, Idaho, and Michigan - BIG NUMBERS - Complete destruction of a very weak opponent.
"The really big numbers will come on Super Tuesday. Also, WAY UP ON CROOKED JOE!" Trump concluded.
"Birdbrain is a loser, record low performance in virtually every State," the former president continued in another post. "DeSanctus easily beat her in Iowa for a VERY DISTANT second place, and then she ran up to the podium, before he had a chance to do so, and claimed victory."
"I enjoy watching the Bird disavow her PLEDGE to the RNC and her statement that she would NEVER run against President Trump ('A great President')," he continued. "Well, she ran, she lied, and she LOST BIG!"
Trump and Haley will face off in 16 more state primaries tomorrow.
Haley has vowed to remain in the race through Super Tuesday regardless of her performance.
