The top Democrat in the Senate said in a Sunday television interview that he plans to introduce legislation that would give Congress a say in whether President Trump can ease sanctions against Russia.

“Senator Cardin and I are introducing legislation this week to say that, before the president could reduce any sanctions on Russia, that it would have to be passed by Congress,” Senate Minority Leader Charles E. Schumer (D-N.Y.) said on ABC’s “This Week with George Stephanopoulos.”

In a recent interview with the Wall Street Journal, Trump said he was open to lifting sanctions on the Russian government if Russia proves helpful to the United States in some areas.

“That would be horrible,” Schumer said on ABC.

The Democratic leader said his legislation would have bipartisan support from Sens. John McCain (R-Ariz.) and Lindsey O. Graham (R-S.C.).

“We need more sanctions against Russia. We should not relax them,” McCain said in an interview on the same program.
