All these requirements [the requirement to register RT as a foreign agent] contradict the American principles of freedom of speech.
The US doesn’t prohibit RT broadcasting in America, but requires this television company to: submit periodic
disclosures outlining its agreements with the foreign principal, disclose income from and expenditures on behalf the principal, and have
business records of its activities available for inspection by the United States Department of Justice (DOJ). In addition, a foreign agent must ensure that all informational materials it distributes are conspicuously labelled and filed with the DOJ. http://www.atlanticcouncil.org/publications/reports/agent-of-influence-should-russia-s-rt-register-as-a-foreign-agent
During the Cold War, representatives of Soviet news outlets (TASS, ‘Pravda’, ‘Izvestia’ and others) were registered agents,” ( http://www.newsweek.com/time-shine-light-putins-american-propaganda-arm-542642 ).
