Was told russias agenda in an email that was sent to set up a Campaign Meeting with a russian lawyer. Margaret brennan is at the white house with the next move for trump jr. Margaret, good morning to you. Reporter good morning. Well, donald trump jr. Has hired a lawyer to help with all matters related to russia and this ongoing fbi investigation. Though he has not been formally asked, trump jr. Said he is willing to cooperate with congress. Rest assured, donald trump jr. Will be somebody that we want to talk to. Reporter Senate IntelligenceCommittee Vice chairman mike warner called for donald trump jr. To share details with his meeting last june with natalia veselnitskaya, a Russian National who indicated she could offer damaging information on Hillary Clinton. According to the New York Times, donald trump jr. Had been explicitly told via email that the meeting was part of a russian government effort to aid his fathers campaign. In response to that allegation a lawyer for trump jr. Told cbs news quote, this is much ado about nothing. Don jr. Had no knowledge as to what specific information, if any, would be discussed. His father knew nothing about it. This is the first time the public has seen clear evidence that senior level officials of the Trump Campaign met with potentially an agent of a Foreign Government to try to obtain information that would discredit Hillary Clinton. Reporter donald trump jr. s account has evolved since the meeting was first revealed by the New York Times. On saturday trump jr. Told the times the meeting was primarily about adoptions. Later he admitted damaging information about Hillary Clinton was the pretext for the encounter. He insisted it was nothing unusual posting a sarcastic twitter message. Obviously im the first person on the campaign to ever take a meeting to hear info about an opponent. The revelation about the meeting contradicts several accounts from white house officials. This was Kellyanne Conway in december. Did anyone have any contact with russians trying to meddle with the election . Absolutely not and i discussedthat with the president elect last night. Those conversations never happened. Reporter in february when the president was asked directly whether anyone on the campaign had contacts with the russians he answered for himself only. Well, i had nothing to do with it. I have nothing to do with russia. Reporter former Campaign ChairPaul Manafort as well as the president s soninlaw, jared kushner, were also present in that meeting. Something that kushners representatives say he initially overlooked but did recently disclose as part of a background check for his security clearance. Charlie . Thanks, margaret. Cbs news chief washington correspondent and face the nation anchor John Dickerson joins us now. Good morning. Good morning. Lay out the risk for donald trump jr. And donald trump sr. Well, the first risk is on the question of collusion. The big part of this investigation, it doesnt necessarily show that there was collusion in the scheme but it shows that don jr. Was collusion curious. So he was apt and anxious to meet with this person who said they might have damaging information and if the New York Times is right they were coming in at least one of emails propsing it was coming from the russian government. The second big problem is there were these blanket denials that margaret talked about that have now been undone and so it just adds even more skepticism to the official comments coming from the white house. Now, in terms of the president , this is obviously closer to him. He has never been at the center of the collusion story. And this is obviously moves it closer to him, that not only was his son involved but the highest levels of his campaign went to this meeting. Donald trump jr. s lawyer says this is much ado about nothing. What do you make of that characterization . And how unusual is it for a campaign to meet with the Opposing Side to get negative intel . Well, campaigns do lots of underhanded things with opposition research. Thats absolutely true. Usually they pawn it off to lower level staffers or theres somebody who nobody sees out in the daylight who takes care of this stuff. This would be three of the arguably the most top people involved in the campaign participating in a meeting where if you believe the accounts was was set up just as a meeting from somebody coming from russia with bad information. Thats a pretty flimsy pretext for a meeting to get that kind of high level attendance. This doesnt usually happen in campaigns. You go back to 1968 when the Nixon Campaign worked with both sides of the vietnam war to slow things down because they thought that would help humphrey but thats a long time ago. There have been instances in the 2000 campaign, al gores top aide got information that was secret about the bush debate preparation. He immediately turned it over to the fbi. So this has happened but not that often. And thats exactly my question. There are at least three sources in the New York Times who say this was in an email. I mean, there is proof of this that that email said this is part of a russian government effort to aid the Trump Campaign. Thats what this meeting was about. Shouldnt Law Enforcement have been alerted immediately . Well, you would you would hope so. You know, on the other and so thats the point. This is not just any country. This is an adversary or an enemy of the United States offering this information. On the other hand, if there was a collusion that was going on, a connection between the russians and the Trump Administration or the Trump Campaign, youd think they would have had Better Communications than just this email that sort of came in over the transom. So theres much to investigate here, but the the reaction is definitely not the one you would you would expect and not the one you would want if you knew people would someday be looking at it. Is it possible we may see donald trump jr. Testify in congress . He said hed cooperate so presumably that would be the expectation of cooperation would be to testify and answer questions from both parties have asked for that. Thats right. Thank you so much.
