That was part of the NDAA Act of 2016, IIRC. The stated reason was to allow Voice of America type broadcasts to be heard in Detroit and other locations of Foreigners.
The argument was that if everyone else in the world can hear them, why not inside the USA. They also set up a “ministry of truth” - I forget which Govt. Agency that was assigned to.
Since they have been propagandizing and lyin’ for decades with mockingbird media, can’t really blame that on the law that just passed. It’s the censorship that’s being made legal. Soon we’ll have our very own Bagdad Bob.
Actually the date on the propaganda may have been earlier. I know they passed some sort of sneaky stuff into 2016, but I can’t remember what went where. That NDAA is always around Christmas, it seems and sneaky as all get out.
