The Trump administration has lifted sanctions on three companies, including the aluminum giant Rusal, linked to Russian oligarch Oleg Deripaska. Democrats had led a push in Congress to continue the restrictions.

Earlier this month, Senate Republicans blocked an effort to keep the sanctions on Rusal, En+ Group and JSC EuroSibEnergo.

Some lawmakers from both parties have said it is inappropriate to ease sanctions on companies tied to Deripaska, an ally of Russian president Vladimir Putin, while special counsel Robert Mueller investigates whether Trump’s 2016 presidential campaign colluded with Moscow.

Deripaska had ties with Paul Manafort, Trump’s former campaign manager. Manafort pleaded guilty in September 2018 to attempted witness tampering and conspiring against the United States.
