I recall that Rush or Mark Steyn said he didn’t understand all the hullabaloo around McCain jetting to Russia to return with the document. It was already in the hands of the Obama Administration.
…Anyway, talk about collusion!
McCain did not travel to get dossier.
He sent someone to England to pick up the Dossier (that at least is the story).
Then he “said” he hand delivered it to Comey.
But yes, Comey and ComDems surrogates already had it.
