FBI Director Kash Patel is planning to visit Russia later this year, likely in mid-October, the Politico reported, citing a U.S. official and a person familiar with the situation.

Axar.az reports according to publication, it would be an unusual and sensitive trip for an FBI chief to one of America’s top adversaries.The plans come as Washington and Moscow continue to be at odds over the war in Ukraine, with U.S. lawmakers demanding the imposition of heavy new sanctions on Russia.

According to the U.S. official familiar with the travel plans, Patel is scheduled to visit Russia on Oct. 14-15, first stopping in Moscow and then St. Petersburg. His host is likely to be the FSB, the Russian security service that is heir to the Soviet-era KGB, the official said.

It’s not clear if Patel will meet with Russian leader Vladimir Putin or any of his senior political aides. Also unclear is what is on his agenda for discussion.

As with any such plans by U.S. officials, they are tentative and subject to change.
