DeSantis wouldn't comment on Trump when asked about him during a press conference in Key Biscayne.
When reminded Trump was a Florida resident, DeSantis shot back: "I also got 22 million others."
Trump has been living in Palm Beach, Florida, at Mar-a-Lago, his home and private club, since leaving the White House.
The criticism starting even before Election Day, when Trump nicknamed DeSantis "Ron DeSanctimonious," and said DeSantis should show more gratefulness after Trump supported DeSantis for governor in 2018, rocketing him to the GOP nomination.
Reporters haven't asked DeSantis about the dinner in the two press conferences he held in Florida this week, but other prominent Republicans, including potential 2024 rivals, have condemned the meeting.
