A bipartisan Senate contingent has introduced what Republican Lindsey Graham has called the “sanctions bill from hell,” targeting Russia and President Vladimir Putin.

The legislation, which was introduced just as senators were departing for a shortened August recess on Wednesday, targets Russian oligarchs and Putin family members for additional sanctions, and it would seek to require a two-thirds vote of the Senate for any attempt by the U.S. to abandon NATO.

“We must confront this challenge — not as Republicans or Democrats, but as Americans. Because ultimately, Putin’s true aim is to undermine all of us — our country, our freedom, and all that America stands for,” said Armed Services Chairman John McCain of Arizona, who has joined in the Graham-led legislation.

Graham, a Republican from South Carolina, teamed up with Foreign Relations ranking Democrat Robert Menendez of New Jersey in leading the latest legislative push.

Menendez noted in his statement that President Donald Trump and his administration has not used all of the tools at its disposal to counter Russian efforts to interfere in American democracy.
