Not too long ago, former South Carolina governor and U.N. ambassador Nikki Haley was standing her ground as the last GOP candidate in the not-so-competitive presidential primary race against her former boss, Donald Trump. Also the first high-profile primary candidate to challenge Trump for the 2024 Republican nomination, Haley waited until after Super Tuesday to suspend her campaign.

These days, she’s sending fundraising emails on her former rival’s behalf. “I served under President Trump in his administration as the Ambassador to the United Nations,” Haley wrote in one Trump-Vance fundraising email blast that went out Friday morning. “It was clear then as it is now that the United States and the World are safer and stronger with President Trump in the White House.”

This fundraising pitch comes after Haley said she planned to vote for Trump in May at an event hosted by the Hudson Institute, where she now serves as the conservative national-security think tank’s Walter P. Stern chair. Then in July, she took the stage at the Republican National Convention in Milwaukee and urged her supporters to support his candidacy. “We should acknowledge that there are some Americans who don’t agree with Donald Trump 100 percent of the time. I happen to know some of them,” Haley said in her GOP convention speech. “You don’t have to agree with Trump 100 percent of the time to vote for him.”

It’s unclear at this point in the race whether the 2024 GOP ticket plans to have Haley appear at Trump-Vance campaign events in the lead-up to Election Day. Earlier this month, Haley told CBS’s Face the Nation that she’s “on standby” to campaign for the GOP nominee.
