"Our journalists have no choice here. They are working in the country, where slogans do not match the deeds. The conditions for the operation [of media outlets] are constantly deteriorating.

"There should be no doubts that retaliatory — adequate and proportionate — measures will follow," the spokesperson added.
Several Russian outlets have come under pressure in the United States, as lawmakers and intelligence community claimed that the media may have been involved in Russia’s alleged 2016 US presidential election meddling.
Earlier, RT America and Sputnik Radio's partner Reston Translator that rebroadcasts radio programs had to register as a foreign agent in the United States under the FARA, after Justice Department's request.
