Oleg Deripaska, who was sanctioned in 2018 by Washington, is a tycoon linked to the Russian energy sector.
The FBI searched the Washington DC home of Russian oligarch Oleg Deripaska on Tuesday, linked to Russian President Vladimir Putin, US media reported.
After speaking with an FBI spokesperson, the television network NBC News was the first to report the search, who did not specify the reasons.
Deripaska is an energy sector magnate related to Putin and one of the Russian figures sanctioned in April 2018 by the US Treasury Department, who accused him of bribery and threatening competing business people.
The Treasury said at the time that the oligarch had "bribed a government official, ordered the murder of a businessman and had links to a Russian organized crime group. "
Deripaska also has financial ties to Paul Manafort, the former head of former President Donald Trump's 2016 election campaign who was convicted of fraud due to special counsel Robert Mueller's investigation into the so-called Russian plot.
Manafort was one of the people from Trump's environment who were indicted in the framework of those investigations for his consulting work in Ukraine.
During the process against the former campaign manager, court documents came to light, detailing that Manafort received a loan of 10 million dollars from Deripaska in 2005.
The mogul sued the United States government over the sanctions imposed on him in 2018. Still, a federal judge dismissed the case last June.
According to NBC, the US authorities have repeatedly been denying him a visa from the country in recent years because of his alleged ties to organized crime.
However, the Russian government recently granted him diplomatic status, which allowed him to enter the US and have diplomatic immunity, the network said, citing officials and former officials from the country.
In 2019, the Donald Trump administration lifted sanctions on the Russian aluminum giant Rusal and its subsidiary En +, two controlled companies, Deripaska.
At the time, the Treasury Department explained that the two companies had reduced Deripaska's share and agreed to welcome independent individuals from the United States and the European Union to their board of directors.
Under the agreement, the tycoon will reduce his shares in those companies below 50%, and his voting rights will be around 35%.
