Agents of a foreign power must register. Otherwise illegal.
“FARA mandates that you must register before acting as an agent of a foreign principal. Under Section 612(a) of FARA, parties must file a registration statement within 10 days of having agreed to act as an agent of a foreign principal. A party may not begin to act as an agent of a foreign principal before registering.”
“Agents of a foreign power must register. Otherwise illegal.”
Agreed.
However, it is not sufficient to show that somebody is representing the ideas and interests of a foreign government, it must be proved they are being paid by that government to pursue its interests.
Enforcement is wildly selective and varied to the extent you gotta have somebody dead to rights. Or it’s thrown out.
After they spend all their money on lawyers and lose their job.
