John Brennan was the American progenitor of political espionage aimed at defeating Donald Trump. One side did collude with foreign powers to tip the election — Hillary’s.
Seeking to retain his position as CIA director under Hillary, Brennan teamed up with British spies and Estonian spies to cripple Trump’s candidacy. He used their phony intelligence as a pretext for a multi-agency investigation into Trump, which led the FBI to probe a computer server connected to Trump Tower and gave cover to Susan Rice, among other Hillary supporters, to spy on Trump and his people.
John Brennan’s CIA operated like a branch office of the Hillary campaign, leaking out mentions of this bogus investigation to the press in the hopes of inflicting maximum political damage on Trump
