investigation found more than 3,000 election-related ads, tsting more than $100,000, paid for by a russian company with links to the kremlin. facebook said, "the vast majority of ads didn't specifically reference the u.s. presidential election or a particular candidate, but sppeared to focus on amplifying divisive social and political messages." the ads have not been made public but will now be turned over to congressional investigators. for months, however, facebook denied there was any evidence that russians had paid for election-related advertising. senator mark warner is vice chairman of the senate intelligence committee. >> i feel like facebook finally has been responsive, but the proof will be in the extent of the materials they give us next week, and then will they continue to work with us to identify other sites that may have originated in russia. they've identified one russian troll farm. >> reporter: the identity of ad buyers should not have been a

mystery to facebook says this security expert. >> they should know those addresses are coming from in this case an enemy nation state, russia. >> reporter: zuckerberg will make it easier for users to identify who is paying for political advertising on facebook. >> we can't prevent all governments from all interference, but we can make it harder. >> reporter: the issues raised in the ads and the fact that they were targeted at specific parts of the country has raised suspicion the russians may have had some help from n the united states. anthony. >> mason: john blackstone, thanks, john. the special counsel russia's investigation has cast a wide net for documents. could they include the "spicer files?" chief white house correspondent major garrett has been looking into that. te reporter: this associated press photo of then-white house press secretary sean spicer appears to validate new reporting from the website axios that spicer kept copious notes during the campaign and while at the white house.

those notes have drawn the attention of special counsel robert mueller. but the portion of spicer's notes visible on close-up in the picture refer to top administration officials. ad.p." for then-chief of staff reince preibus. rex for secretary of state rex tillerson. the photo was shot at an april press conference with president trump and the secretary general of nato. contacted by cbs, spicer refused comment on the photo or the euggestion his notes could become part of mueller's investigation into russian meddling and the trump campaign. on abc this morning, spicer deflected all mueller-related questions. >> has the mueller team reached out to you at all? >> i'm not going to discuss that issue at all. >> have you hired a lawyer? >> i'm not going to discuss that issue at all. >> so you haven't been subpoenaed? >> i'm not going to discuss that issue at all. >> did you ever here inside the white house that mueller should be fired? >> i'm not going to discuss that issue at all. >> reporter: as press secretary, spicer tried several ways to undercut the russia story.

>> if the president puts russian tlad dressing on his salad tonight, somehow that's a russian connection. >> reporter: cbs news has confirmed mueller is likely to request an interview with spicer. we also learned interviews with white house officials past and present could begin as early as ndxt week. anthony. >> mason: major garrett, thank you, major. a study out today says former football star aaron hernandez had a severe form of c.t.e., the degenerative brain disease found in people who have received repeated blows to the head. hernandez took his own life in prison this year. james brown, host of the "n.f.l. today" and a special correspondent for cbs news, has more on this. h reporter: aaron hernandez was once on top of the world. five years ago, he was considered one of the best young stars in the n.f.l. >> guilty of murder in the first degree. r: reporter: but by this past april, he was a convicted murderer, serving a life sentence when he killed himself in prison.

his family decided to donate his brain to the boston university c.t.e. research center, and seday his lawyer, jose baez, released the results: >> aaron hernandez had an advanced, stage three, of c.t.e., which is usually found in the median age of a 67-year- old man. >> reporter: hernandez was 27 when he died. according to researchers, symptoms of chronic traumatic encephalopathy include depression, aggression, and suicidal tendencies. hernandez's family blames the n.f.l. for his death, suing the league and the new england patriots for an unspecified eyount of money, claiming the league did not disclose to players what it knew about head injuries. t> our client may have been able t understand what was actually happening to him, and that could have ultimately prevented his death. >> reporter: hernandez displayed a history of violence dating back to 2007 when as a freshman at the university of florida he allegedly punched a worker at a restaurant.

in 2013, he was convicted of murdering a friend, oden lloyd. he had just been acquitted in a different double-murder case when five days later, he committed suicide. >> when hindsight is 20/20, you look back and there are certain things we may have noticed, but you don't know. ut reporter: 110 out of the 111 brains of former n.f.l. doayers donated to research at oston university were found to have c.t.e. anthony, you might recall that the n.f.l. agreed just about four years ago to a $1 billion settlement in a brain injury lawsuit brought by a group of former players and their families. aaron hernandez was not part of that lawsuit, but researchers tday said hernandez had the most severe case of c.t.e. ever hund in someone his age. anthony. >> mason: a tragic story. thank you, j.b. te earthquake death toll in mexico rose today to at least 273. more than two days after the

magnitude 7.1 earthquake reduced buildings to rubble, survivors are still being rescued. manuel bojorquez is there. >> reporter: at the start of the day, rescuers believed a 12- year-old girl was still trapped in this crumbled school. ooe drama riveted a traumatized nation as crews used thermal cameras to figure out a way to reach her. ( whistle ) later they brought a teacher to the scene, believing the girl might hang on if she heard a familiar voice. but by late afternoon, the government announced the signs of life were likely an adult, possibly a janitor, not a student after all. elsewhere in the capital, crews mounted seemingly impossible rescues through small cracks in the rubble. pulling survivors to safety. ( applause ) others mourned. near the epicenter, 11 members of one family were killed when a church collapsed during a baptism.

t e violent quake struck on the exact anniversary of the catastrophic 1985 quake that killed nearly 10,000 people. but this time, the city's seismic warnings sounded, and people ran into the main square. engineering professor sergio alcocer says it's a new line of defense, as are stronger building codes. >> i would say the type of structure now being used in mexico city now is a structure where more walls are being used aside from just columns and beams. and that makes the structure stiffer and stronger. >> reporter: stricter building codes did not prevent this collapse. guadalupe salinas is still searching, waiting for her son, listavo. do you wish you could be in there yourself, searching yourself for him? her son is among more than 40 people listed as missing from

the collapsed office building behind me. and you can see from the wet roads here that a thunderstorm rolled through this evening, hampering the rescuers' efforts. anthony. >> mason: manuel bojorquez in mexico city. great reporting there, manny, thanks. t 's been a day of rescues in another natural disaster, hurricane maria in puerto rico. david begnaud is there. >> reporter: in the small town of toa baja, hundreds of residents were rescued by the national guard. most packed into trucks, while scores of others waded through eto feet of water, carrying what's left of their possessions. in the san juan suburb of cantano, residents forged through flooded streets, heading to the only open grocery store. only five were allowed in at a time to avoid chaos. maria inflicted damage on 80% of the homes here, and like the rest of the island, there is no power or phone service. we rode with the mayor as he

surveyed the damage and watched these young men help police rescue a 91-year-old man in a kayak. outside that man's house, his neighbors wept. his home was surrounded by chest-deep water. "how are you feeling?" i asked him. "i'm good, thanks to the virgin mary," he said. it wasn't any different in levittown, where teams went house to house, rescuing the sick and elderly. s this shelter, residents nervously checked makeshift lists, looking for names of family members who are safe. a nice longoria has been looking for her 77-year-old aunt since yesterday. >> she's an elderly person, so i don't know how she--... it's hard. >> reporter: and for those families who were able to reconnect, words can't describe. the governor of puerto rico says tho-thirds of this island are a disaster zone tonight.

the airport in san juan reopened today, but only for military and emergency operations. erd amid this misery, you should know we've seen resilience. as one man told us with a smile on his face, "we're used to this." anthony. >> mason: david begnaud, thank you, david. it wasn't a missile this time. tonight, kim jong-un shot off his mouth calling president trump a "mentally deranged doter," and warning he'll pay dearly for his threats which you'll recall, include wiping north korea off the map. earlier in the day, mr. trump slapped new economic sanctions on the north, but his efforts to get kim to the bargaining table may be jeopardized by his threats to scrap the nuclear atal with iran. here's white house and senior foreign affairs correspondent margaret brennan. >> reporter: president trump wants to renegotiate the 2015 atreement that froze iran's nuclear program in exchange for lifting financial sanctions. >> that deal is an embarrassment to the united states, and i

don't think you've heard the last of it. >> reporter: he wants a longer, more-stringent deal and is trying to force the issue by accusing iran of not complying with the terms of the existing deal, even though all five other signatories, including russia and china, say otherwise. so does the secretary of state. >> iran is in technical compliance of the agreement. >> reporter: iranian president hassan rouhani said his country will not renegotiate, and warned a u.s. pullout would have broader implications. is there a diplomatic way out? "talking would be a waste of time," he said, "and in the future, no other government would be willing to negotiate with a country that tramples on les commitments." "alking away from the iran deal may also complicate u.s. attempts to get north korea to agree to give up its nuclear weapons. senior national security iontributor michael morrell: >> so if we back away in any way ayom our nuclear agreement with iran, we send a signal to north korea that a future president might unravel their deal, too.

so it is a disincentive, strong disincentive for north korea to come to an agreement with the united states. >> reporter: secretary of state rex tillerson said he is optimistic that the u.s. can handle both threats. >> the threat's the same, but fhe nature of the agreements are going to be quite different in terms of what's necessary to achieve the objective to denuclearize north korea and iran that never pursues nuclear weapons. >> reporter: i asked u.n. ambassador nikki haley if walking away from the iran nuclear deal makes it harder to broker one with north korea. her response: "it doesn't undermine u.s. credibility, but shows the president is looking rit for the american people." anthony. >> mason: thanks, margaret. and coming up next on the cbs evening news, the impact of flint's tainted water on the health of women and babies.

problems. eyan reynolds is in flint. >> reporter: when 41-year-old nikyea wakes looks at the thtrasound images of the twins she lost two years ago, her anger is evident. >> i believe the flint water crisis, the lead in the water, caused me to have my miscarriages in 2015. >> reporter: back then, she was drinking and bathing in the water pumped to her home by the city of flint. to save money, the city had switched its water source to the flint river because it was eteaper than the water it had been getting from detroit. but it was so corrosive it leached lead from her pipes right into her faucet, and last year when she had her water tested, lead concentrations of 1,100 parts per billion were found. the e.p.a. says safe levels should be no higher than 15 parts per billion. >> we were taking showers and baths and was breaking out with- - i don't know what it was. like, they weren't scabs but they were, like, bumps and stuff all over our bodies.
