Giuliani, Trump's lawyer, did an interview on CNN in which he discusses this whole thing.
http://transcripts.cnn.com/TRANSCRIPTS/1807/26/CPT.01.html The other people in the room during the alleged Russian Dirt conversation matter, as they can verify if Cohen is telling the truth or if Trump/DonJr is telling the truth. Two interesting bits:
CUOMO: Well, hold on a second. If the president knew about that meeting at Trump Tower in advance --
GIULIANI: He didn't.
CUOMO: If he did, it matters Rudy. It does.
GIULIANI: It does. It's not a smoking gun. It matters.
Already shifting to the narrative to, well, if Trump knew his campaign was attempting to collude with Russian agents against a political opponent, that's not a smoking gun! It's fine! Also:
GIULIANI: He didn't know about it. I know that. I've been over this in great detail. I've talked to the corroborating witnesses. This guy is walking into a trap. But --
CUOMO: You've talked to the other people that were in the room?
GIULIANI: Of course I did. Months ago. A month ago. Two months ago.
CUOMO: And you know what they say the president was told and not told by his son?
GIULIANI: I know what they say, yes.
So Giuliani talked to the witnesses who were in the room during this particular conversation, about this exact subject, two months
prior to Cohen making this allegation. To my ear this sounds like the campaign
knew this allegation might come up about this particular conversation once they found out Cohen had been raided and would be pinched for info, which coincidentally, happened.....about two months ago. If this conversation was invented out of whole cloth by Cohen, how and why would Giuliani have conversations with these very witnesses about this very topic two months ago if, as he claims, nothing of importance was ever said during this conversation to begin with? Stinks like rotten fish.
