They know how to play this game. They will have been sizing up the administration expertly over the last little while, looking for any opportunity to strengthen those links, hoping that the candidate they clearly favored in the u.

Reporter blum represents a district that twice voted for barack obama but turned red in november. In marshaltown blum was repeatedly forced to defend the president. No proof so far of any collusion between the Trump Campaign and russia. Reporter among the Trump SupportersMaurice Mcwhirter was not worried that firing the fbi director might impede the bureaus investigation. One guy even if its the head guy doesnt make any difference to whether or not that investigation goes forward or not. Reporter fellow trump supporter veridee hand was even less concerned.

Homeland Security Officials briefed the airlines today on a proposal to expand the ban on laptops to include more foreign flights coming to the u. S. Cbs news was first to report on the plan. Heres transportation correspondent kris van cleave. Reporter the proposed ban is based on growing concern about an explosive getting past airport scanners. The ban, already in place at ten airports in the middle east and africa, prohibits electronics larger than a cell phone in the passenger cabin. If expanded it could potentially impact all of the 60 european airports with direct flights to the u. S. The bottom line is keeping terrorists with explosives off planes.

It presents a challenge, how do you do that in a way that is efficient and effective .

And thats the overnight news for this friday. For some of you the news continues. For others check back a little later for the morning news and cbs this morning. From the Broadcast Center in new york city im anthony mason. Announcer this is the cbs overnight news. Welcome to the overnight news. Im jericka duncan. James comey may be gone, but the investigation into russian influence on the president ial election and possible collusion with President Trumps associates continues. Comeys replacement, Andrew Mccabe, went before the Senate Judiciary committee, and he wasted little time dispelling much of the white house rationale for comeys sudden firing. Jeff pegues begins our coverage. Reporter inside fbi headquarters there are growing concerns the white house is trying to get in the way of the bureaus russia investigation. In the wake of james comeys firing one federal Law Enforcement official tells cbs news, there is a whole lot of interfering happening. The person added, this is a crisis. We consider it to be a highly significant investigation. Reporter on capitol hill acting fbi director Andrew Mccabe told the Senate Intelligence committee the investigation is on track. You cannot stop the men and women of the fbi from doing the right thing. Reporter despite a request last week by comey for more resources, mccabe told the senators today agents have the manpower and money they need to determine whether Trump Campaign officials were coordinating with the russians during the 2016 campaign. Mccabe also pushed back on white house claims that comey was unpopular. Democrat martin heinrich. Is it accurate that the rankandfile no longer supported director comey . No, sir. That is not accurate. I hold director comey in the absolute highest regard. I have the highest respect for his considerable abilities and his integrity. And it has been the greatest privilege and honor of my professional life to work with him. I can tell you also that director comey enjoyed broad support within the fbi. And still does to this day. Reporter at the white house today Spokesperson Sarah Huckabee Sanders said she had proof fbi agents were happy to see comey go. You personally have talked to countless fbi officials, employees. Really . Like so are we talking between like email, text messages, absolutely. 50 . Yes. 60 . 70 . Look, were not going to get into a numbers game. I have heard from a large number of individuals that work at the fbi that said that theyre very happy with the president s decision. President trump gave his first interview since firing comey. The president insists that comey told him on three different occasions that he is not the subject of the russia election scandal investigation. Major garrett has that. Hes a showboat. Hes a grandstander. The fbi has been in turmoil. You know that. I know that. Everybody knows that. Reporter President Trump said today he was going to fire james comey no matter what advice he received from attorney general Jeff Sessions or Deputy Attorney general rod rosenstein. I was going to fire comey. Theres no good time to do it, by the way. Because in your letter you said i accepted their recommendation. So you had already made the decision. Oh, i was going to fire regardless. Reporter that directly contradicts the process outlined by Vice President pence, counselor kellyanne conway, and Deputy Press SecretarySarah Huckabee sanders, who said the president acted tuesday after receiving a memo from rosenstein. And i personally am grateful that we have a president whos willing to provide the kind of decisive and strong leadership to take the recommendation of the Deputy Attorney general. He acted decisively today. He took the recommendation of his Deputy Attorney general. The Deputy Attorney general made that recommendation. Reporter the president also said he asked comey if he was a target of the bureaus russia investigation. They spoke about it three times. Over dinner at the white house and twice on the phone. I actually asked him, yes. I said if its possible would you let me know, am i under investigation . He said you are not under investigation. President s typically try to avoid the appearance of interfering with or influencing an investigation. Today sanders defended the president s actions. I dont see that as a conflict of interest and neither do the many legal scholars and others that have been commenting on it for the last hour. Nancy cordes now with the view from capitol hill. I trusted jim comey. Reporter the president s showboat comment about comey drew instant pushback today from the leaders of the Senate Intelligence committee. I found him to be one of the most ethical, upright, straightforward individuals ive had the opportunity to work with. Reporter comeys firing has consumed the capitol. This is an astonishing chain of events. Reporter prompting rare bipartisan agreement. I do have questions about both the rationale and the timing and certainly have communicated that to the white house. Reporter but the two sides still part ways over the need for a special independent prosecutor. We need the support of republican members of congress. Reporter utah republican orrin hatch. Every time we have any controversy around here they call for a special prosecutor. We have a Justice Department thats very capable. Reporter ultimately it isnt up to congress. Its up to Deputy Attorney general rod rosenstein, who wrote that critical comey memo. Democratic leader Chuck Schumer sent rosenstein a list of 27 questions today. Did the president or anyone else direct you to write your memo . Were you aware when you drafted it that it would be used to justify comeys firing . Rosenstein came to capitol hill today. Not to answer questions but to meet with the leaders of Senate Intelligence. Did mr. Rosenstein confirm that he threatened to quit over the handling of the comey firing . And did you ask him about that . We didnt ask him about it. He didnt share it with us. We were focused on deconfliction. The fcc is considering new tactics to crack down on those annoying robocalls. More than 29 billion robocalls bombarded Americans Last year. Thats 90 calls for every man, woman, and child in america. Anna werner has that story.

Have some explaining to do. A pregnant woman was tested last year for the zika virus and was told she was clean. Now it turns out she was infected. Theres no word if the baby was hurt, but the virus can cause severe birth defects, and theres an outbreak right now in texas. Dr. Jon lapook reports. Reporter when we first met 23yearold roseio morado of brownsville, texas last month she was 36 weeks pregnant and doctors were seeing problems with her baby on ultrasound. We do see some what we call kalsifications in the brain. Reporter morado tested positive for zika infection. The virus is carried by mosquitos both in brownsville and across the border in mexico, where she visited family early in her pregnancy. Im kind of sad. But i know everything is going to be okay. Reporter this is her baby, hugo. How are you feeling right now as a new mother . I feel so happy. Im so in love with him. Reporter hugo was born almost three weeks ago with the small head characteristic of microcephaly and faces an uncertain future in terms of his development. For right now hes doing okay.

Reporter of the 18 pregnant women who tested positive for zika infection, one other baby born last month also has microcephaly. Seven babies appear normal. And nine pregnancies are ongoing. I dont know what to tell patients that live here in brownsville. That want to have a family. What do you tell those moms . And theyre definitely at risk of having babies that potentially could be damaged. Reporter those people behind me are crossing over from mexico over there to the United States over here. With so many people going back and forth between mexico and the u. S. Every day, its hard to know when somebody tests positive for zika exactly where they picked it up. The virus can be spread both by mosquito bites and sex. With no vaccine available, Health Officials are focusing on prevention through Mosquito Control and patient identification because once a pregnant woman is infected there is no treatment to protect the baby. In the meantime, well keep watching and screening. Watching and screening and feeling helpless. Scottw warmer weather comes mosquito breeding season, and a big question is whether the virus will now spread more widely to mosquitos along the gulf coast. A vaccine is not expected to be ready until next year at the earliest. The u. S. Military spends about 4 billion a year building new submarines. The latest generation are technological marvels.

Still, says captain brian sidlow, no country carries the international influence of the United States navy. The United States through our submarine force for nearly 100 years now has gained and maintained a strong undersea advantage. Reporter 2 billion is a lot of money, but one of the reasons why it isnt more than that is the unique way those ships are constructed. Theyre built in modular sections which are then combined.
