interesting how your standards shift on proving things false.
The Flynn thing - Comey testified a couple interesting things: 1) he never felt Trump was ordering him to do anything, he never felt pressured and it was never brought up again. 2) the context that the lying charges against Flynn were suspect (per Comey's testimony the agents didn't think Flynn was lying). The WH knew all this (as documents have shown) at the time of Trump's request. It was a "come on man, could you stop jerking him around, he's a good man" comment explaining why Comey didn't take it as an order or even serious request.
A few facts have been proven wrong - some names and dates. More importantly, the FBI has not been able to verify the information. So does it need to be proven false to be considered not of material use?
How can collusion occur if no information was provided? Can you show me anywhere that documents material information was provided and used in the election? Besides, most of the collusion accusations center on the Wikileaks/DNC stuff which was not connected to the TT meeting (at least I haven't seen anything linking them).
Also you are ignoring the Comey, Mueller and members of Gang of 8 comments saying Trump is the not the target of the investigation. Everything in the 3 areas above has been known for quite some time and predates comments from those in the know that Trump is not the target.
Look, I won't convince you but maybe you see how IMO proven is a world different from actually proven.
