From the Document: "Sanctions are a central element of U.S. policy to counter and deter malign Russian behavior. The United States has imposed sanctions on Russia mainly in response to Russia's 2014 invasion of Ukraine, to reverse and deter further Russian aggression in Ukraine, and to deter Russian aggression against other countries. The United States also has imposed sanctions on Russia in response to (and to deter) election interference and other malicious cyber-enabled activities, human rights abuses, the use of a chemical weapon, weapons proliferation, illicit trade with North Korea, and support to Syria and Venezuela. Most Members of Congress support a robust use of sanctions amid concerns about Russia's international behavior and geostrategic intentions."
