It has been suspected strongly
In 1960s until 1968 the SDS (communist college group) worked to destroy America/Capitalism. Chomsky, Allen Ginsberg (bro to Ruth), Clintons, and other now politicians, professors, and other Democrats decided to infiltrate important positions and destroy America....hence, what we see now!
There was a resurgence of the SDS (Students for Democratic Society (Marxism) on college campuses taught by old members in past 20 yrs. Combined with SOROS Org & his paying demonstrators make them a danger. Antifa must be one of his payoffs. I think they should be declared a terrorist org.
