Trump and DeSantis could end up in a competitive primary for the 2024 GOP presidential nomination.
Now, Trump says he might reveal unflattering information about DeSantis if that happens.
"I think he would be making a mistake, I think the base would not like it — I don't think it would be good for the party."
If he runs, he runs," Trump went on to say.
Casey DeSantis, the Florida governor's wife, is "really running his campaign," Trump also said, according to a Wall Street Journal report.
