>> pelley: in a presidential campaign more about insults than ideas, it has come to this-- the biggest issue today of a beauty queen of 20 years ago, and donald trump's treatment of her. in the wee hours of the morning, while most of us were sleeping, trump was wide weak launching a twitter tirade. can hillary clinton was quick to fire back, and here is major garrett. >> tweets began at 3:20 a.m. eastern with donald trump condemning unsourced reporting about his campaign as lieses. at 5:15 a.m., to the dismay and bafflement of his top advisers, trump turned to alicia machado, and the week-long debate over trump's mocking of the 1996 miss universe winner's post-pageant weight gain. trump called machado "disgusting" and urged his nearly 12 million twitter followsers to look for a sex tape of machado, the first time a presidential nominee recommended pornography to his voters. trump said:: machado has appeared twice in mexico's "played boy "magazine. trump's allegation of a sex tape appears to be a reference to a spanish-language reality tv show. on instagram, machado responded writinwriting in spanish trump s intimidating her with cheap slander and lies what have no foundation. during a brief tour today of the gerald ford presidential museum: >> mr. trump, why did you go on a late-night tweet storm last night. >> reporter: trump ignored questions about his predawn twitter antics and at a later rally tried on return attention to his adversary. >> mr. president, will you pledge not to issue a pardon to hillary clinton and her coconspirators for their many crimes against our country? ♪ high enough >> reporter: but clinton has seized on the machado story, telefoang the beauty queen today and on twitter asking, "what kind of man stays up all night to sneer a woman with lies and conspiracy theories?" >> he called this woman "miss piggy." >> reporter: it was clinton who brought up machado at monday's debate in hopes of worsening trump's image with female voters and she hit the same point again today in florida. >> i mean, his latest twitter meltdown is unhinged, even for him. it proves yet again gathat he is temperamentally unfit to be president and commander in chief. >> reporter: at this rally, trump said his debate performance was uneven at times because of a faulty microphone. and today the bipartisan debate commission admitted trump's voice was distorted in the debate hall but not for the television audience. privately, senior trump advisers conceded on his day he garbled his best anti-clinton attack lines admitting the microphone had nothing to do with it. >> pelley: major garrett, thanks. well, with a clear microphone we trust, let's bring in john heilemann, comanaging editor of bloomberg politics. john, our clinton campaign correspondent nancy cordes told us today when a candidate is digging a hole for himself his opponent should just stand back and watch. but today, clinton brought a shovel, why? >> well, you know, up to help in should cases. the thing is, the other candidate, if your opponent is digging a hole for himself, you let him keep digging but occasionally you want to throw dirt on top of him and hope to bury him and that's what the clinton campaign is trying to do right now with donald trump. he had a not very good debate on monday night and over the course of the next four days he made things worse for himself, and worse for himself as news cycle unfolded and hillary clinton is trying to put a stake in his heart at the end of this week. >> pelley: and she's picking up some momentum in the polls again. it seems like any other candidate would change the subject as quickly as possible. >> right. >> pelley: but with this, with the family of the fallen soldier, with the judge in the trump university case, trump keeps these controversies going for days. >> right. he does not like to be attacked. he does not like to have his credibility undermind. he can't resist taking the bait. and in these cases it's really dangerous, scott, because those are all instances-- the ones you mentioned-- instans of a presidential nominee taking on a citizen. voters have tolerance for politicians attacking each other but they don't have tolerance for attacking people like them can and that's how they see people like alicia machado. they're just average people trying to get along their lives and when big, powerful politicians decide to dump on them in this way, it leaves a really bad impression. >> pelley: john heilemann, bloomberg politics, thanks for being with us. >> thanks, scott. . >> pelley: the next debate ised it. it will be between the vice presidential candidates. the moderator will be my colleague elaine quijano of our streaming news service, cbsn. our coverage will begin at 9:00 eastern time. well, we have just been briefed by the national transportation safety board yesterday's commuter train crash in new jersey. one person was killed. of the 108 injured, only seven remain in the hospital tonight. kris van cleave has the breaking news. >> reporter: national transportation safety board investigators have starred interviewing the crew of the new jersey transit train that crashed into the hoboken station yesterday. the engineer, 48-year-old thomas gallagher, is said to be cooperating, and has provided a blood sample that will be screened for drugs and alcohol. investigators recovered the data recorder from the rear of the train, but are still waiting to access the front cab. n.t.s.b. vice chair bella dinh-zarr: >> once the n.t.s.b. has a successful download, investigators will use that information to validate speed and get that information about train. >> reporter: investigators will examine the train for signs of mechanical failure, including any brake problems. investigators are also gathering and reviewing multiple sources of video. lead investigator jim southworth: >> because of the asbestos, because of the unsettled structures that we're not sure about, i'm not allowing anybody to go in there, okay. none of the evidence that's in there is perishab. >> reporter: gallagher is a 29-year transit employee described as an experienced engineer. sources tell cbs news so far the investigation has found no red flags in his background, work, or medical history. he was treated and released from a hospital hours after the crash. >> it takes a very quick minute, maybe, for this to happen and it takes quite some time to unravel, particularly with the amount of data we get. >> reporter: while investigators stress it is too early to know what caused this accident, scott, over the last 20 years, nearly a third of all derailment accidents have been blamed on human error. in new jersey, that number jumps to nearly 60%. >> pelley: kris van cleave for us tonight. kris, thank you. police have interviewed and cleared two men seen handling one of the bombs left on the street? of in new york earlier this month. both worked for egypt air. hay found a suitcase with a pressure cooker bomb inside. apparently, they uponned the bag, so they took the bomb out and left it on street. the bomb did not explode, but blocks away, a bomb allegedly left by ahmad ramadi, wounded 31. late today, police in el cajon, california, released videos showing tuesday's fatal police shooting of a black man. 38-year-old hollandeo is seen pointing an object at officers. he was immediately shot and tased. what he was holding turned out to be an electronic cigarette. his sister called the police because he was acting erratically. the shooting near san diego was followed by three nights of protest can which turned vice president last night. this evening, 275,000 civilians are under attack, according to the i united nations. they're besieged in eastern aleppo, which rebelled against the syrian dictatorship more than five years ago. russian and syrian warplanes are trying to finish them off. today, rescue workers pulled a child from a collapsed building. the miracle and the exhaustion were overwhelming. one the of the most experienced reporters on the syrian war is our elizabeth palmer. >> reporter: for nearly two weeks, it's been like it this-- russian and syrian warplanes and artillery pounding eastern aleppo. they're targeting islamic fighters who control much of this side of the city, at least that's what the russians and the the syrians say. but can their aim really be this bad? one after another, civilian targets have been hit-- a bakery, the vat of dough still rising, people's homes, and two of east aleppo's remaining hospitals, which has left doctors utterly overwhelmed. rarely have conditions been this bad, says dr. rick brennan of world health organization. >> children and other civilians are being treated on the floor in corridors. there aren't enough intensive care beds. four children died in the last few days because the spencive care unit in one of the hospitals was full. >> reporter: in the last 48 hours, there's been some ground fighting, as iraqi and iranian militias have joand assad's depleted army. but there's no reason to think they're going to retake eastern aleppo any time soon, which simply puts terrified civilians trapped in the city in the lean of even more fire. the bombing this week, scott, does look like a deliberate campaign of terror to force civilians to flee. the united nations certainly didn't pull its punches. it called it a war crime. >> pelley: elizabeth palmer in our london newsroom tonight. liz, thank you. today, israel buried its last founder. shimon peres helped build israel's military and then worked half of his life for peace. holly williams is in jerusalem. >> reporter: they came from all over the world to jerusalem to pay their final respects to a man who tried to bring peace to his people and to the middle east. president obama called shimon peres a giant. >> the last of the founding generation is now gone. shimon accomplished enough things in his life for 1,000 men. >> reporter: palestinian leader mahmoud abbas was also here, and shared a rare handshake with israel's prime minister, benjamin netanyahu. as israel's foreign minister, shimon peres opened secret negotiations with want palestinians, can which led eventually to the oslo accordses in 1993, the first agreement between israel and the the palestinians aimed at ending their conflict. it won peres the nobel peace prize though it didn't deliver lasting peace in the middle east. he was, said bill clinton, our complicated, brilliant friend. >> he lived 93 years in a state of constant wonder over the unbelievable potential of all the rest of us to rise above our wounds, or resent ams, our fears to make the most of today and claim the promise of tomorrow. >> reporter: in a final farewell, they heard one of shimon peres' favorite songs from his childhood in poland, a jewish prayer "our father, our king." shimon peres was laid to rest today atop mount herzl, scott, alongside other israeli leaders, including prime minister yitzhak rabin, with whom he shared the nobel prize. >> pelley: holly williams in jerusalem. holly, thank you. today, alabama's chief justice was suspended without pay for the last two years of his term. roy moore was found guilty of ethics violations for ordering state judges not to issue same-sex marriage licenses. moore of suspended in 2003 after he refused to remove a 10 comams monument from the the court lobby. coming up on the cbs evening news, a new report finds flaws in the poib's background checks for gun buyers. and steve hartman with a and steve hartman with a crime-stopping cowboy "on the road"." wrote existential poetry. and uncle john was an explorer. i inherited their can-do spirit. and their double chin. now, i'm going to do something about it. kybella® is the first of its kind injectable treatment that destroys fat under the chin, leaving an improved profile. kybella® is an fda-approved non-surgical treatment for adults with a moderate amount of fullness... or a bit more. don't receive kybella® if you have an infection in the treatment area. kybella® can cause nerve injury in the jaw resulting in an uneven smile or facial muscle weakness, and trouble swallowing. tell your doctor about all medical conditions, including if you: have had or plan to have surgery or cosmetic treatments on your face, neck or chin; have had or have medical conditions in or near your neck or have bleeding problems. tell your doctor about all medicines you take. the most common side effects are swelling, bruising, pain, numbness, redness, and areas of hardness in the treatment area. find a doctor at mykybella.com did you or anyone in your household work around asbestos-containing gaskets, packing, or equipment?
