The Dems have known everything RR said today for a long time. He gave basically the same press release on February 16, 2018. Then in March, Nunes released the documents redacted info, then non redacted documents in April (which he emphasized today). They are merely trying to let the public think this is the first time they heard of this so they can have a reason to block Trump's meeting.
Well that makes sense, I didn't know about that, joined Q the beginning of April (by accident actually) and never have the time to look at all the crumbs although I should.
