1. A single official document naming Donald J. Trump under any investigation criminal or otherwise.
2. Any of his whitehouse or campaign under any criminal investigation for collusion with Russia that influenced the election.
3. Proof that The third party source the reporters are quoting is 100% reliable .
4. That Trump did anything at all other then being liked more then Hillary.
1. I think a memo written by the FBI director is an official document.
2. Unless you believe the FBI is investigating the letterhead used during the campaign. It"s safe to assume his campaign staff is under investigation, especially considering the memo in point one, outlines that Trump asked the FBI director to stop, wait for it....... The investigation into Flynn talking to the Russians during the transition.
3. Most of those third party sources get subsequently validated by a tweet by the president.
4. He did say sexuall assault on woman is OK if you're him. It's on tape. He did say he fired Comey because among other things, he didn't like how the investigation was run. It's on tape.
He did admit to give the Russian information. It's on HIS twitter account. So yea he did more than something.
