Andrew Tate and his brother, Tristan Tate, the online influencers who decamped last month to the United States while facing human-trafficking charges in two European countries, were set to return on Friday to Romania ahead of a criminal proceeding, one of them said Friday.

The British American siblings were expected to arrive at night in Bucharest, Romania’s capital, a representative for them told The New York Times.

The pair, who have millions of followers on social media and are known for their misogynistic views and for flaunting their wealth, arrived in Florida on Feb. 27 after a Romanian court lifted travel restrictions against them.

“Spending 185,000 dollars on a private jet across the Atlantic to sign one single piece of paper in Romania,” Andrew Tate wrote Friday on X. “Innocent men don’t run. THEY CLEAR THEIR NAME IN COURT.”

The Tates’ visit to the United States was polarizing and spawned speculation about whether President Trump, with whom the brothers have openly aligned themselves, had used his influence to allow them to travel. But Mr. Trump said he knew nothing about it.

They received a chilly reception from two top Florida officials, with Gov. Ron DeSantis saying that they were not welcome there and the state’s attorney general, James Uthmeier, also a Republican, opening a criminal investigation into them.
