Senate leaders struck an agreement Monday to roll out additional sanctions on Russia and make it difficult for the President to lift them.

The Senate Foreign Relations and Banking Committee announced a deal that had the support of the committee’s top Democrats and Republicans that’s expected to attract wide bipartisan support.

The proposal would provide for a congressional review process if the executive branch eases current sanctions on Russia. And it imposes new sanctions in a number of categories, including those “conducting malicious cyber activity on behalf of the Russian government” and “supplying weapons to the Assad regime.”

The measure would also authorize assistance for European countries concerned about Russian aggression, and require a study on the “flow of illicit finance involving Russia and a formal assessment of US economic exposure to Russian state-owned entities.”

The legislation is expected to be attached as an amendment to an unrelated bill involving sanctions on Iran.

Sen. Bob Corker, chairman of the Senate foreign relations committee, had previously been hesitant to take up a Russia sanctions bill in his committee. But he said last month that he wanted to see progress with Russia or else he would move a sanctions measure.

Despite mixed signals from the President and his administration this year over sanctions, a senior source on Capitol Hill said the White House is not fighting congressional efforts to push through the measure.
