Just hours ago President Trump met with pope francis at the vatican and toured the basilica and the Sistine Chapel then new developments in the Russian Investigation and learning that President Trump is expected to hire a private legal team to deal with the special counsel in congress and more on that in a moment. First to rome where senior White House Correspondent cecilia vega has more on the pope and the president. Good morning, cecilia. Reporter hi, george. Good morning from rome. As you know these are two leaders who dont see eye to eye on a number of issues. They had that very public feud during the campaign over immigration. But today that first facetoface at the vatican and both seem to genuinely get along. President trump at the vatican this morning, a ceremonial arrival complete with the red carpet and swiss guards. His first meeting with pope francis, first lady melania wearing a veil here too. A slow procession to meet the holy father, President Trump seeming to take it all in. Because he will come out in honor of you. Reporter the president s entourage including daughter ivanka and soninlaw jared waiting outside as the poresidet entered the popes Public Library before they got down to business. Welcome. Thank you very much. Reporter the meeting lasting about 30 minutes. At times the president beaming alongside a very serious pope. This facetoface comes after their very public feud last year. The pope called building a border wall unchristian then candidate trump took him on. A religious leader to question a persons faith is disgraceful. Reporter but today the two sides hoping to find Common Ground. Even on areas of disagreement like the environment, the pope gifting the president with a book of his writings on the subject, also a medal, a sim bolling of peace. We can use peace. Reporter the entire white house delegation invited in to meet him. The first lady asking the pope to bless a rosary. Ivanka trump said she was humbled and the two men who so publicly clashed today ending their meeting in a handshake. I wont forget what you said. Reporter yes, so there were no cameras inside for the meeting between the president and pope but we are hearing about what they discussed and talked about the situation in the middle east and the protection of Christian Communities around the world, a number of International Affairs issued talked about here. Later today President Trump heads to brussels where he has that meeting on nato. All important. All right, cecilia, thank you. More on the russia investigation. Former skai director john brennan testifying on capitol hill saying he was troubled by Trump Campaign associates and the russians and this as the president is expected to hire a private attorney. Mary bruce has those details for us. Reporter good morning. Despite his repeated claims he is not under investigation, the president is now expected to hire a private attorney to represent him in the special counsels investigation as the former cia director says definetively he knew during the campaign there were interactions between the two and told the russians to back off. It should be clear to everyone that russia brazenly interfe interfered. Reporter blunt talk on capitol hill tuesday. Former cia director john brennan. For the first time brennan reviling that during the president ial campaign, i confronted his russian counterpart about their meddling in the u. S. Election. I told that if russia had such a Campaign Underway it will be certain to backfire. Reporter brennan making a bold statement saying he was so concerned about potential ties between the trump team and the russians, he felt the fbi should investigate. It raised questions in my mind again whether or not the russians were able to gain the cooperation of those individuals. Reporter he stopped short of calling it collusion and the white house took notice. In a statement the administration stressing that despite a year of investigation there is still no evidence of any russia Trump Campaign collusion but that is still under investigation and now the Washington Post reports President Trump asked two of his top intelligence officials to publicly deny any coordination between his campaign and the russians. We are in a phase where there is a new revelation every two or three days. Reporter one of those officials, the director of national intelligence, would neither confirm nor deny. Its not appropriate for me to comment publicly on any of that. Reporter now, in response, the white house continues to point out that so far no one has presented any evidence of collusion and they still insist that the real story here are the leaks coming from the white house. George. Okay, mary, thanks. More on that from our chief White House Correspondent jon karl and a lot of news in director brennans testimony and basically learned why the fbi investigation got started, his concern about these contacts, the white house choosing to emphasize other parts of his testimony. Reporter yeah, although it was striking, george, to hear him give that testimony and use the word treasonous to describe the underlying allegation here. He said that its even possible that it could have been unwittingly treasonous if there had been americans tied with the campaign colluding with the russian, in other words, they might not have known they were dealing with russian operatives but what the white house is focusing on is that even john brennan who has a clear political interest here, clearly tied to democrats, you know, one of Barack Obamas top advisers even back in his campaign, even john brennan says he has seen no evidence, no hard evidence of any collusion between the Trump Campaign and the russians thats what theyre focusing on but its also settling in on the white house that theyll have to be in for the long haul, special counsel is going to do his work. Congress is going to do its work and a lot of these things that they are now blaming on leaks are going to become public. Reporter absolutely, george. And you see the president is now retaining outside counsel and soon will have his own outside law firm to deal wit. Inside the west wing senior staff have been notified, warned, anything can be subpoenaed. Even their text messages. Only a matter of time before you see that senior staff needing to lawyer up, big legal bills. This is something that is daunting on the white house and realize this investigation is for the long haul and its going to affect all of them. Jon karl, thanks very much. Boy, that is something to see up close, once those investigations start in the white house it has a Chilling Effect on all the work and thats why the president is trying to hire an outside counsel to try to contain it as best he can. And you know that. Lets go to rob marciano with the Severe Weather threat across the southeast. 38 Million People are in its path and, rob, there were 11 thats right michael across three states.
