Orban only shared a quick handshake with US President Joe Biden while sharing the stage with him at the NATO summit in Washington.
"Can confirm," the source said when asked about reports of the Trump-Orban meeting.
Orban will travel to Florida after attending the final day of the NATO Washington Summit. Orban recently met with Russian President Vladimir Putin and Chinese President Xi Jinping as part of his diplomatic effort to open up lines of communication to resolve the conflict in Ukraine.
White House National Security Adviser Jake Sullivan told reporters earlier that Orban's travels have not been aligned with US foreign policy.
