For once I have to agree with Washington Post.
This is an incredibly great video on the Foreign Agents Registration Act.
In particular, FARA requires any foreign entity of any kind operating inside USA to disclose the fact that it is a foreign entity – especially in any communications it diseminates. That includes any advertising or public relations.
Russian news outlet RT was operating in the US illegally for years without such registration.
Will Trump crack down on the Indian Mafia in the US and force them to comply? Or not?
