A tweet from NBC News reporter Tom Winter:
Sounds like whatever was lawfully seized during the raid is extremely incriminating. And many articles have come out speculating that Cohen has audio tapes of his conversations with clients. If he has Trump colluding and/or obstructing on tape, that would be devastating.
Whatever the documents and/or records are, it’s a good sign that a raid is successful when the target screams, “hey — you can’t look at that!”
I’m not a lawyer, but I can’t imagine this legal argument succeeds very often.
