A bipartisan group of senators reintroduced a bill Wednesday to increase pressure on Russia through strong sanctions in the face of what they call “Kremlin aggression” toward the U.S. and its allies.

Sens. Bob Menendez, D-N.J., Lindsey Graham, R-S.C., Cory Gardner, R-Colo., Ben Cardin, D-Md., and Jeanne Shaheen, D-N.H., co-signed the Defending American Security from Kremlin Aggression Act which “seeks to increase economic, political, and diplomatic pressure on the Russian Federation” for it’s interference in democratic processes and recent actions in Syria and Ukraine.
