Florida Gov. Ron DeSantis lashed out at former South Carolina Gov. Nikki Haley one last time as he dropped out of the presidential race this week.

DeSantis blasted Haley as a representative of "corporatism" and emphasized his endorsement for former President Trump. Haley is now the sole remaining challenger to Trump in the GOP primary.

"I signed a pledge to support the Republican nominee and I will honor that pledge. He has my endorsement because we can’t go back to the old Republican guard of yesteryear – a repackaged form of warmed-over corporatism – that Nikki Haley represents. The days of putting Americans last, of kowtowing to large corporations, of caving to woke ideology, are over," DeSantis said.

DeSantis dropped out of the 2024 Republican presidential race and endorsed former President Donald Trump on Sunday, just two days before the New Hampshire primary.

The Florida governor announced his decision to suspend his campaign in a social media video on X, formerly known as Twitter.

"If there was anything I could do to produce a favorable outcome, more campaign stops, more interviews, I would do it," DeSantis said in the video. "But I can't ask our supporters to volunteer their time and donate their resources if we don't have a clear path to victory."

"Accordingly, I am today suspending my campaign," said DeSantis, who was a distant third in the single digits in the latest polls in New Hampshire.

DeSantis highlighted that he's had "disagreements" with Trump but believes that the former president is a better leader than Biden.

"It's clear to me that a majority of Republican primary voters want to give Donald Trump another chance," DeSantis continued. "They watched his presidency get stymied by relentless resistance, and they see Democrats using lawfare this day to attack him."

Trump himself said on Sunday that he is "honored" to receive DeSantis' endorsement.

"Very honored to have his endorsement," Trump told Fox News Digital. "I look forward to working together with him to beat Joe Biden, who is the worst and most corrupt president in the history of our country."
