Dear morons, for starters it isn't illegal to visit Prague even if he met Putin himself there to begin with. But more importantly, this has already been debunked. It was a different Michael Cohen that a "third party" searching the FBI database found. The problem with that is months before the FISA court made a ruling that this access was illegal. So whoever the 3rd party was not only was given illegal access after this ruling they obtained illegal data and also got the wrong person.
About the ruling..
