A phony dossier manufactured by Trump hating British intelligence operative Christopher Steele with help from unnamed Russians, and paid for by the Hillary Clinton campaign, was taken to James Comey by John “sneaky-Pete " McCain and a State Department official, most likely John Kerry, in order to smear the reputation of Donald Trump and subvert the election.
Ironically, the same phony dossier was used by the Obama administration's Justice Department and FBI to obtain secret FISA warrants to spy on Donald Trump's campaign. The phony dossier was also used as grounds to open a relentless and never-ending investigation into Trump-Russian collusion. It should be obvious to anyone with common sense that the primary goal of the investigation is take down the Trump administration.
