Former South Carolina Gov. Nikki Haley on Tuesday announced her 2024 presidential campaign, making her former President Donald Trump's first opponent for the Republican nomination.

Haley, who served as ambassador to the United Nations for two years in the Trump administration, is expected to deliver her in-person announcement speech Wednesday in Charleston.

“It’s time for a new generation of leadership — to rediscover fiscal responsibility, secure our border, and strengthen our country, our pride and our purpose.” Haley said in her video announcement.

Haley accused the "socialist left" of seeing "an opportunity to rewrite history."

"China and Russia are on the march. They all think we can be bullied, kicked around," Haley said. "You should know this about me: I don’t put up with bullies. And when you kick back, it hurts them more if you’re wearing heels. I’m Nikki Haley, and I’m running for president.”
