The top Republican and Democrat on the Senate Intelligence Committee signaled Wednesday that they do not oppose the Treasury Department’s decision to loosen sanctions on three companies owned by a Russian oligarch with links to Russian President Vladimir Putin and key players in Ukrainian politics, including former Trump campaign chairman Paul Manafort.

Congress has 30 days to nix the deal Treasury Secretary Steven Mnuchin has struck with Oleg Deripaska, who currently owns the largest non-Chinese aluminum producing company in the world and two other multibillion-dollar energy companies.

Deripaska, who is close with Putin and for years bankrolled Manafort’s political consulting work in Ukraine, will cede business control and his majority ownership stakes in the companies in exchange for sanctions relief, the Treasury Department announced Wednesday.

Deripaska’s net worth shrank by nearly 50 percent after the Trump administration enacted a congressional sanctions package in April that included a robust response to Russia’s 2016 election interference.

Two of his companies took multibillion-dollar hits to their value.
