Michael Morell (former CIA director), Michael Hayden (former head of both CIA and NSA), James Clapper (former National Intel director), John Brennan (former CIA director) and Dan Coats (Trump’s own director of national intel) have all either explicitly stated or at least very heavily implied Trump is a Russian asset. These are not exactly libtard conspiracy theorists.
And Russia and Trump have largely accomplished this by operating within the law, not by breaking it. America is a country where massive amounts of money can be laundered through real estate, anonymously, at virtually 0 risk, after all.
