FBI at Russian oligarch's home for 'law enforcement' action

WASHINGTON: Federal agents conducted "law enforcement activity" on Tuesday at a Washington mansion owned by Russian oligarch

Oleg Deripaska

, a close ally of Russian President Vladimir Putin.

The agents were carrying out "court-authorized law enforcement activity," an agency spokesperson said. Officials would not provide any additional information about the circumstances surrounding their presence or any information about potential investigations involving Deripaska.

The wealthy Russian who made his money in the aluminum business is a close ally of Putin and was mentioned multiple times in special counsel Robert Mueller's report on interference in the 2016 presidential election.

Deripaska also had ties to

Paul Manafort

, former President Donald Trump's former campaign chairman, who was convicted of eight financial crimes as part Mueller's investigation. Manafort was later pardoned by Trump.

The

Treasury Department

, under the Trump administration, had also lifted financial sanctions on three companies connected to Deripaska. Officials said at the time they had done so because Derapaska's direct and indirect shareholding stake in the three companies had been reduced to the point that he no longer has control over them.
