If I recall (and correct me if I'm wrong), but she didn't exactly support him in the end. So, she's changed her tune?
Nikki Haley says she won't run against Trump if he mounts presidential bid in 2024Former South Carolina Gov. Nikki Haley said Monday that she would not run for the presidency in 2024 if former President Donald Trump mounts another campaign for the White House.
Haley served in the Trump administration as U.S. ambassador to the United Nations from 2017 to 2018. She is considered a potential contender for the GOP’s presidential nomination in 2024. When asked if she would support Trump if he runs again, Haley responded, "Yes."
"I would not run if President Trump ran and I would talk to him about it," Haley told the Associated Press. "That’s something that we will have a conversation about at some point, if that decision is something that has to be made. But yeah, I would, absolutely."...........
