Transcript for Mike Flynn's links to the Russia puzzle

Backed general plan for just the second and this is this a potential immunity. Look his lawyer has said he has a story to tell and he wants to talent right we know. That he is past interactions with the Russian officials and is actually failure to disclose those. Is what led to his departure from the White House in the first place vote. What is it exactly that we think we might learn from his testimony which parts of the narrative are they looking to fill in from general plan. There's a couple of the questions regarding general plan one is what was he talking to the Russian ambassador now now that we know that he had those communications now that he know that we had those conversations despite his. Denials during the transition. Out what exactly was being communicated did talk of Russian sanctions come off. Our doorstep accomplice talked to Vladimir Putin's right hand man today on Good Morning America. And there was no denial about the possibility of that conversation only about whether they would have been inappropriate. For them to have it now. The official Russian position is that what wouldn't be because that would be the decision makers console like sanctions. Anyway so that's one item another big one is the financial ties between Flint and Russia. We know that he accepted a large sum of money to come over give a speech to RT formally Russian T Russia to today which is at an arm of the Russian government he net flattener potent. On that trip this is that they believe two years ago so what was communicated and that have any connection to any official actions and did he talk to anyone else involving the Russians that he get any direction from Donald Trump or others. On the what's intriguing to me is that it is a couple possibilities and asking for immunity one is he knows he's in trouble of some sort. And that he's looking to find some legal copper the other which is what his lawyer says is that it's such a frenzy political environment. He wants to make sure that he's protected and the question becomes. What information does he hat is it is it information that is exculpatory that makes Donald couple good in the top associates and makes all seem innocuous. In which case it's hard to imagine what you need immunity for is it something that would reflect on any of his superiors there are many superiors. In that orbit other than the president of the United States himself and I would just add that the that the Flint involvement. To my mind is different than the other day's paper like Roger Stone on Matta for. Because Flynn was actually. The national security advisor for a short period time but for several weeks so in an and during our transition people knew he was in line for top post so. His contacts are potentially much more interest they. Much more intriguing to investigators that something that happened last summer that would have had something do with with business relationships the other thing that that I. It was interesting today from Sean Spicer is that he is creating almost an alternate reality for journalists to to try to tend to. In talking about the clintons' ties to Russians and a suggestion that has no basis in fact that maybe that Hillary Clinton herself at inappropriate. Contacts with the Russians. And the in creating the use of the wiretapping story line and in looking around the trading information. That is a big focus from the White House to be a shockingly big focus of the White House right now they want to talk about that they wanna make it about that despite the fact that. Here we are at the end of march this month has been consumed by a trump tweet that had no basis in fact. And to keep going on this on that I also thought it was interesting that Sean Spicer Brett white house Press Secretary asked point blank. Is there anything that you are concerned about about what general Flynn might saying he had a one word answer that answer was no. Just like that they're not worried about what general Flynn might say.
