A bipartisan group of U.S. lawmakers plans to pressure Treasury Secretary Scott Bastian at the NATO summit in Ankara to revive a stalled Russia sanctions bill.

Introduced by Senators Lindsey Graham and Richard Blumenthal, the bill would give the president authority to impose sanctions and tariffs on countries trading with Russia, including buyers of Russian oil and uranium. Lawmakers also want Bastian to refuse to extend additional waivers for Russian oil.
