But Trump didn't know that. This is a man who believes that Barack Obama went back in history and paid off not just the registrar of births in Honolulu but the Births and Deaths writers at the local newspaper. He also thinks that a black bible-thumping congregation agrees with him that he knows the Gospel, that millions of wetbacks voted illegally for Someone Not Donald Trump, and that he has a seven handicap in golf (with scores kept on the honor system, by a man with no honor).
He believed, which is why he asked for them, just as the vaunted Congressional committees believed.... that buried in those emails was going to be an email from Hillary to Obama saying, "Well, **** 'em. We can always get a new ambassador. We can't send in troops to Benghazi because our best friend the Ayatollah won't like it."
Collusion and conspiracy do not require that there was actually anything of value in those emails, just that The Donnies thought there was.
