gases. the e.p.a. notified fiat-chrysler today and said failing to disclose the software amounts to a clear and "serious violation of the clean air act," and could "result in harmful pollution in the air we breathe." >> why these are there, what they do, and why they have to be designed the way they are. >> reporter: david clegen is with the california air resources board, which issued a similar warning to the automaker today. >> they did not disclose them to the regulatory agencies that were certifying the vehicles. and the second is, when these things are activated, they do put out more emissions than the law allows. >> reporter: the diesel vehicles are still safe to drive, but the allegations are similar to those leveled at volkswagen. yesterday, the german automaker agreed to plead guilty to three felony counts for its use of software that circumvented u.s. emission standards. one executive has been arrested. that scandal has cost v.w. at least $20 billion and prompted additional e.p.a. scrutiny of disease dooezle vehicles, leading to today's action against fiat-chrysler. in a t

reporters, fiat-chrysler c.e.o. sergio marchionne angrily denied the charges and said, "anyone that tries to drawt comparison between us and v.w. is smoking illegal material." now, v.w. -- skews me-- fiat-chrysler faces up to $$4.6 billion in potential fines. scott, it's already had an impact on the company's stock price, closing down more than 10% today. >> pelley: and no word yet on what owners of these vehicles are supposed to do. kris van cleave, thanks very much. cbs news has learned that the japanese company takata is negotiating a billion-dollar settlement over its handling of the air bag ruptures. the company is also expected to plead guilty to fraud. takata's air bag inflators can explode, shooting metal through the car. 11 deaths and 180 injuries have been reported in the u.s. as many as 69 million air bags have been recalled.

in u.s. history. sources tell cbs news that f.b.i. director james comey personally briefed president-elect trump last friday about scandalous tales about mr. trump that were never proven and were nonetheless attached to an official u.s. intelligence report. makehas been looking into this. >> reporter: cbs news has confirmed that christopher steele, seen in this photo, produced the memo containing unsubstantiated claims that russia had compromising personal and financial information about president-elect donald trump. steele is a former british intelligence officer who works for orbis business intelligence, a private investigation firm in london. orbis was originally hired by fusion g.p.s., a d.c.-based research firm working for an unknown client. the unverified claims circ laipted widely in political and media circles

last week, the u.s. intelligence community included a summary of the information in a classified briefing with mr. trump who said the memo was phony. >> i think it's disgraceful, disgraceful, that the intelligence agencies allowed any information that turned out to be so false and fake out. and that's something that nazi germany would have done and did do. >> reporter: director of national intelligence, james clapper, phoned mr. trump last night. in a statement, clapper said he expressed hills "profound dismay" at the leaks and emphasized the unverified document is not a u.s. intelligence community product. president obama and vice president biden also received the briefing. on msnbc, the vice president was asked if including the claims was appropriate. >> it was their obligation to inform not only us but the president-elect that this was out there. so that it didn't come out of the blue and have any impact o on-- on the conduct of

>> reporter: house speaker paul ryan told cbs news he understands mr. trump's frustration, calling the leaks and subsequent media frenzy unfair. but, scott, the speaker said he would not have suggested u.s. intelligence agencieses use nazi tactics in this or any other matter. >> pelley: major garrett, thanks. at his confirmation hearing today for secretary of defense, retired general james mattis broke with mr. trump's conciliatory position on russia. mattis called russia america's number one threat. dr. ben carson, who has been nominated for housing secretary, told senators that he understands the needs of the poor after growing up in inner-city detroit. well, just when you thought you had heard the last of hillary clinton's emails, a new investigation was opened today. this time, it's the inspector general of the justice department looking into how the f.b.i. and f.b.i.

here's our justice correspondent jeff pegues. >> reporter: the inspector general's probe goes to the heart of the investigation into secretary clinton's private email server. it will examine allegations that policies and procedures were not followed by f.b.i. director can james comey. it will also look at whether a certain official should have recused themselves, and if nonpublic information was inappropriately given to the clinton campaign and the media. >> this is going to be an unusual statement in at least a couple of ways. >> reporter: comey broke with f.b.i. protocol when he publicly announced in july that secretary clinton would not face charges. >> we did not find clear evidence that secretary clinton or her colleagues intended to violate laws. >> reporter: then, 12 days before the election, the director wrote to congress that he had reopened the investigation after agents discovered emails on a laptop used by clinton aide huma abedin that appeared to be pin

election, he sent another letter, once again clearing clinton and closing the probe. >> correct, i don't-- especially in a public forum. >> reporter: at a senate hearing tuesday, comey declined to discuss any potential investigations into president-elect donald trump or his associates, prompting this response from maine senator angus king: >> the irony of your making that statement here i cannot avoid. >> reporter: comey says that he will go cooperate with the investigation. scott, in a closed door meeting on california today, he was grilled by some democratic senators who blame the f.b.i. director in part for secretary clinton's loss. >> pelley: jeff pegues, thanks. well, with his last day in office a week from tomorrow, president obama sat down with steve kroft of "60 minutes." >> reporter: you didn't change washington. >> i changed those things that were in direct-- my direct contro

fact with two weeks to go, we're probably the first administration in modern history that hasn't had a major scandal in the white house. in that sense, we changed some things. i would have liked to have gotten that one last supreme court justice in there. i'd like the supreme court to take a look. >> reporter: couldn't even get a hearing. >> but we couldn't even get a hearing. trying to get the other side of the aisle to work with us on issues, in some cases that they professed originally an interest in and saying to them, "hold on a second. you guys used to think this was a good idea. now just because i'm supporting it, you can't change your mind." but they did. and what that did i think made me appreciate-- i have said this before but it's worth repeating because this is on me-- part of the job description is also shaping public opinion. and we were very effective-- and i was very effective-- in shaping public opinion around my campaigns. but there are big

while governing where even though we were doing the right thing, we weren't able to mobilize public opinion firmly enough behind us to weaken the resolve of the republicans to stop opposing us or to cooperate with us. there were times during my presidency where i lost the p.r. battle. >> pelley: steve kroft's interview with president obama this sunday on "60 minutes." today, the senate voted to fast track the repeal of obamacare, but republicans have yet to offer a replacement. millions of americans who depend on obamacare are now wonder what happens next. here's don dahler. >> how we doing with this. >> reporter: small business owner can julie mansfield has a clear vision of what a lack of health insurance would mean to her. >> that would mean going mind. that would lawyer literally mean going blind. >> reporter: 49-year-old restaurateur has a very rare

autoimmune disease that attacks her retinas. she says the specialists and drugs that maintain her sight cost more than she can afford but under obamacare she only pays a $10 coway. >> when the a.c.a. came around it was a bletion. >> reporter: bus others are not so happy with the affordable care act. some maul smallbusiness owners say insuring their employees is financially crippling. and when 59-year-old kevin mccarthy of california signed up in 2014, his premiums increased. >> when we signed up with the new health care act, not only did it cost us 50% more in monthly premiums, but as it turns out, we were also getting 50% less. >> reporter: this year premiums increased an average of 25% but americans continued to sign up. 83% of them receive tax credits. mansfield worries about talk of repealinth

plan to replace it. if you could talk to congress and explain to them whycyw whatr replaces the a.c.a. has to be at least as good as the a.c.a., what would you say to them? >> my health is not about politics. my health is about my life and my livelihood, and it's not to be played with. it's not to be a political pawn. >> reporter: one question many are pondering is whether the replacement would keep some of the more popular aspects of the a.c.a.-- coverage of preexisting conditions, for example, or adult children being allowed to stay on their parents' policy. scott, the deadline for signing up for 2017 coverage is this sunday, but no one knows if obamacare will survive the year. >> pelley: don dahler for us tonight. don, thank you. well, today, vice president joe biden never saw it coming. he was speaking at an event when he was surprised by president obama who had an even bigger surprise in mind.

>> reporter: president obama liked to joke that he and his vice president made up for each other's shortcomings. >> our styles are so different, as well as our experience. and so when he asked me to join him, i asked him why, and he said, "i want you to help me govern because you know the system." >> reporter: they were a generation apart in age. where the president came across as cool, even aloof, joe biden played politics as a contact sport. the president sometimes complained joe talks too much. early on in the administration, his loose lips upstaged the unveiling of the president's health care reform when a mic caught his whispered comments. (bleep) a moment the president recalled today. >> all told, that's a pretty remarkable legacy, an amazing career in public service. it is, as joe once said a big deal. ( laughter ) >> reporter: over eight years, the bond between them seemed to ow

>> this also gives the internet one last chance to talk about our bromance. ( laughter ) >> reporter: the president grieved with him when biden's son, beau, died of cancer. >> to know joe and the rest of the biden family is to understand why beau lived the life he did. >> reporter: biden often said he and the president had each other's back, but today, the president pulled a fast one on him with an unexpected honor. >> the presidential medal of freedom. >> reporter: that's the highest award a president can give a civilian. >> i don't deserve this, but i know it came from the president's heart. i'm indebted to you. i'm indebted to your friendship. >> reporter: joe biden never made it to the nation's highest office, but today, at least, that was all right by him. >> i just hope that the asterisk in history that is attached to my name when theyk

this presidency is that i can say i was part of, part of the journey of a remarkable man who did remarkable things for this country. ( applause )
