And protecting with a style all his own. Not a lot of people are aware of the power they have to make someone happy, to bring a smile to someones face. This is the cbs evening news with scott pelley. Pelley late today, attorney general Jeff Sessions recused himself from the f. B. I. s investigation of russian meddling in the u. S. President ial election. This comes after the Justice Department acknowledged that sessions met with the Russian Ambassador to the united states, Sergey Kislyak, during the campaign. Sessions did not disclose this when he was asked at his confirmation hearing about contacts between the campaign and the russian government. Sessions was a campaign adviser. U. S. Intelligence has concluded the russians tried to influence the election. Now, the f. B. I. Is investigating whether Trump Campaign associates colluded with russian operatives. Last month, the president fired National Security adviser michael flynn, after flynn lied to the Vice President about contacts he had with ambassador kislyak. No Administration Official has been accused of collusion, but questions are being asked about why top Trump Officials have been evasive in explaining their meetings with ambassador kislyak. Jeff pegues has todays developments. In retrospect, i should have slowed down and said, but i did meet one russian official a couple of times. Reporter u. S. Attorney general Jeff Sessions said that he would have no involvement in any investigation related to the Trump Campaign. The announcement came less than a day after sessions acknowledged having two meetings with Russian AmbassadorSergey Kislyak last year, something he did not reveal while under oath at at his confirmation hearing when he was questioned by minnesota democrat al franken. And if there is any evidence that anyone affiliated with the Trump Campaign communicated with the russian government in the course of this campaign, what will you do . Senator franken, i am not aware of any of those activities. I have been called a surrogate at a time or two in that campaign, and i didnt have did not have communications with the russians. Make America Great again reporter in february, 2016, sessions became the first senator to endorse thencandidate trump. He defended mr. Trumps positive comments about russia. Donald trump is right. We need to figure out a way to end this cycle of hostility that is putting this country at risk. Reporter in july, he had a conversation with kislyak at the Republican National convention in cleveland. Then, in september, the two met in the alabama senators capitol hill office. Sessions says the Russian Ambassador initiated the meeting. Less than a month later, u. S. Intelligence agencies would publicly blame the russian government for a wave of cyberattacks targeting the u. S. Election. Ultimately concluding the attacks were designed to help President Trump. The f. B. I. Counterintelligence unit continues to investigate contact betweens Trump Associates and russian operatives. During his confirmation process, sessions was asked in a written questionnaire if he had any contact with the russian government about the 2016 election. He responded, no. He repeated that assertion today. I never had meetings with russian operatives or russian intermeadaries about the Trump Campaign. And the idea that i was tart of a continuing exchange of information during the campaign between trump sursurrogates and intermeadaries for the russian government is totally false. Reporter eric oneill, a former counterintelligence officer for the f. B. I. , says everyone at the Russian Embassy is part of the kremlins spy network. But there has to be that understanding that youre not just talking to a politician or a diplomat. Youre talking to someone who will feed into intelligence. Reporter we now know other Trump Associates also met with kislyak, either during or after the campaign. They include michael flynn, adviser carter page, and mr. Trumps soninlaw, jared kushner. Scott, today, the white house described the kushner meeting as an inconsequential hello. Pelley jeff pegues, thanks. Investigations are also under way on capitol hill where we find nancy cordes. I do think he should recuse himself. Reporter dozens of republicans concluded today that sessions was simply too close to the Trump Campaign to be in charge of investigating it. I would recuse myself if i were in his shoes right now. Reporter Democratic Leaders in the house and senate went further, calling on sessions to resign after 22 days on the job. The top cop in our country lied under oath. There is something very inappropriate to dramatically mislead congress. Reporter why isnt it enough for him to recuse himself . Why does he have to resign . Look, the attorney general is the chief Law Enforcement officer of the land, and already his integrity and independence has been questioned. Reporter sessions served in congress for 21 years and has many Close Friends here. Hes a man of integrity. Reporter they argued today he didnt mean to mislead and had every right as a member of the Armed Services committee to meet with a foreign diplomat. Idaho republican jim risch in the last couple of years, ive probably met with a highranking official of half the countries on the face of the earth. Reporter but given tensions with russia, meetings with that nations envoys arent as common. Oklahoma republican jim inhofe has served on Armed Services for two decades. When is the last time you met with the Russian Ambassador . I dont think i ever have. Reporter committee chair, john mccain, has kept his distance from ambassador kislyak since 2014. I was sanctioned by vladimir putin. And so i doubt if that would be a very pleasant encounter. Reporter democrats say sessions, a former prosecutor, should have known that his testimony was leaving a false impression that he never met with any russian officials. Some republicans, however, scott, say it was just an honest mistake made in hour 11 of a very tense confirmation hearing. Pelley nancy cordes on capitol hill. Attorney jan crawford is our chief legal correspondent. Jan, as you might expect, democrats accused sessions today of perjuring himself before congress. What is is the law on that . Reporter scott, that is var high bar and i see now way attorney general session would be prosecuted for his testimony. To be convicted of lying to congress, you have to give testimony that you know is false, and sessions said this afternoon he was thinking the question related to whether he had contacts in connection with his role as a campaign surrogate, not as a u. S. Senator. So, in that context, and when you look at the actual questions, his statements would not be considered false under the law. Pelley now that sessions has recused himself, what does that mean to the continuing investigation . Reporter well, i mean, democrats are saying that sessions recusal is just not enough, and its a little late since hes been in office for three weeks. And theyre calling for a special prosecutor nowrng a spokesperson for session says he will not be involved in those discussion which means it will fall to the acting attorney general, dana boente, who was nominated by president obama, to decide whether or not a special prosecutor should take over the investigation. Remember, sessions choice for deputy has not yet been confirmed by the senate. And, scott, youre also seeing some calls for an independent, 9 11style commission to investigate any wrongdoing that might not rise to the criminal level. Pelley and the special prosecutor, of course, would take want investigation outside the Justice Department. Jan crawford for us tonight. Jarng thank you. Today, President Trump promised more warships, planes, and weapons to a visit to americas new aircast carrier the gerald r. Ford. Mr. Trump praised the ship but he has been harshly critical of its cost. Reporter nothing sim blielz American Military might more than an aircraft carrier, which is why the president went aboard the navys newest carrier, the gerald r. Ford to promote his plans for the a military buildup. We will give you the tools you need to prevent war and if required to fight expwar only do one thing. You know what that is . Win with. Win were going to start winning again. Reporter but as the most expensive ship ever built, the ford which will begin its sea trials next month, stands for Something Else as well. Ford say poster chyle for how you dont build a ship. Reporter garcia de rayos should know. They were designing the ford while they were building it. Not a good way to build a ship. This is just a dumb way to build any kind of ship, but particularly something as big and complicated as a carrier. Reporter started during the bush administration, the ford incor Incorporated New technologies, including an electromagnetic launch system to replace the trouble catapult. No only price went through the roof, but the schedule just became terrible because because there were so many new technologies and it was so ununproven. Reporter the ford is expected to cost just under 13 billion and thats not counting the aircraft it will carry, including the f35 joint Strike Fighter alcohol cost the navy close to 100 million a copy. Under the current schedule, the ford will not be ready for combat until 2021, which means donald trump will have to get elected to a second term before he can send it into action. Scott. Pelley david martin terpentagon. David, thank you.

Reporter after three years representing Church Sex Abuse survivors on that vatican panel, colquitt, citing a culture of resistance at the vatican. These men, they thrive on secrecy and coverup, and i thought it was time to to move out and be able to speak about it and to let it be known. Reporter councils does not blame pope francis but rather members of the vatican curate, or church administration, saying the lack of cooperation is shameful. They have the same sort of attitude as the Church Leadership here had 20 years ago when i was trying to bring my abuser to justice. And its soul destroying. Its heartbreaking to see that there are still men with those same attitudes. Reporter boston cardinal, sean omalley, who heads the commission said, he will certain listen carefully to all that marie wishes to share with us about her concerns. You tried to convince her to stay. Yes, i tried to convince her. Reporter father hans zollner is part of the same panel set up by pope francis. We need to talk about it, we need to face it, but many people are afraid and are reluctant to touch this because this is ugly. This is horrific. Reporter and that can lead to this lack of cooperation within the vatican curate . Yeah, yes, of course, because you you deal with something that that you better dont look at. Reporter this is not first highprofile keparture. Peter saunders, the only other sex victim on the panel, was sidelined last year. The it is up for discussion as to whether other sex Abuse Victims will be invited to join the panel. Father zollner told us collins resignation may be a tbletion disguise because it focuses attention on the issue. Scott, he told us, even he is if you straighted by the pace of change.
