Former President Donald Trump wouldn’t commit to supporting the 2024 Republican nominee for president if he loses the primary contest.

In an interview with conservative radio host Hugh Hewitt on Thursday, Trump said “it would depend,” when asked if he would support the nominee if he loses.

“I would give you the same answer I gave in 2016 during the debate. … It would have to depend on who the nominee was,” Trump added.

Trump officially announced his run for president in 2024 last November. In his interview with Hewitt, Trump signaled that he’s unlikely to endorse any of his potential opponents in the race.

He called his former U.N. Ambassador Nikki Haley, who is expected to announce she is running for president on Feb. 15, “overly ambitious.”

“She said, ‘I’ll never run against my president. He’s a great president. He’s been our greatest president. I’ll never run. I’ll never run,’” Trump said. “But Nikki suffers from something that’s a very tough thing to suffer from. She’s overly ambitious.”

He also accused Govs. Ron DeSantis and Glenn Youngkin of being ungrateful for not giving him enough credit for their victories. He also claimed he took former Secretary of State Mike Pompeo “out of nothing”.

Asked whether he thought his former allies should not run against him, Trump said: “Yeah, I would say that, but I know how life works. And I know how politics works. And politics is a microcosm, but even more vicious, of life.”
