Donald Trump will meet with Hungarian Prime Minister Viktor Orbán in Florida on Thursday, according to people familiar with the matter, less than a week after he met with Russian President Vladimir Putin in Moscow.

The visit is likely to fan concerns that the Hungarian leader is working as an intermediary between Putin and Trump.

Trump and Putin professed a fondness for one another during the U.S. president’s first term—often garnering bipartisan criticism. More recently, the Republican leader has said he believed he could convince Putin to end his war in Ukraine and release Americans detained in Russia if he were elected to a second term.

Orbán will travel to Trump’s Mar-a-Lago resort after the conclusion of the NATO summit in Washington. His visit to Moscow became a central point of discussion at the gathering, where other allies pledged additional air defenses for Ukraine in its continuing campaign against the full-scale Russian invasion that began in 2022.
