good evening. we begin here tonight with a fresh emotional crescendo in america's ongoing reckoning with sexual assault and harassment. a fifth accuser stepped forward to point the finger at roy moore, who is running for senate in alabama. beverly young nelson said moore sexual assaulted her when she was just 16. will moore bow out? leading republicans, including the president, are weighing in. and tonight moore, himself, and his wife are speaking out. >> mr. moore reached over and began groping me and putting his hand on my breasts. i tried to open my car door to leave but he reached over and locked it so i could not get out. >> reporter: beverly young nelson, detailing a sexual assault from roy moore nearly 40 years ago when she was only 16 years old. >> i tried fighting him off while yelling at him to stop.

but instead of stopping, he began squeezing my neck, attempting to force my head on to chrhis crotch. >> reporter: she is the fifth to accuse moore of sexual assault. the women were all in their teens. moore has denied the allegations and defiantly defended himself again tonight with his wife by his side. >> i never did what she said i did. i don't even know the woman. i don't know anything about her. i don't even know where the restaurant is or was. >> these things are false, and it's ugly, it's the ugliest politics i've ever been in in my life. >> tonight moore is fighting for his political life, not a single republican senator has publicly said they remain behind him and senator majority leader mitch mcconnell went a step further today. >> i think he should step aside. >> reporter: do you believe the allegations to be true? >> i believe the women, yes.

>> on capitol hill, other republican senators echoed those sentiments. >> it was appropriate for me to withdraw my endorsement. >> for the good of your state, yourself, step aside. >> there is a strong possibilities the republicans lose a senate seat in the reddest state in the nation. >> even for a republican in the trump era, moore has stood out, f toting a gun at at campaign rally, riding horseback to the polls. he's never been afraid to buck the system. >> i have acknowledged god is the moral foundation of our law. >> moore made headline when is he installed a giant monument of the ten commandments in the rotunda of the alabama state judicial building. >> we allowed it to be taken

from us. >> he was removed from the bench but later reelected only to be removed again when he defied the federal courts on same-sex marriage. >> it is immoral, defined by the law as detestable. >> president trump supported moore's primary opponent but eventually backed moore, though said he would have to step aside if the allegations are true. >> i would probably have taken what he did to me to my grave had it not been for the courage of four other women that were willing to speak out. >> beverly young nelson, who says she was a trump supporter was the first to come forward with the attorney gloria allred by her side. she said she was working as a waitress at a local restaurant where she said moore was a regular and often flirtation. >> he would speak to me and sometimes pull the ends of my long hair as i walked by him.

>> she said moore, a 30-year-old deputy district attorney wrote in her year book, "to a sweeter girl, i could not say more merry christmas, love roy moore, old hickory house and he signed it roy moore, d.a. >> about a week or two later, she says moore offered to drive her home from work and then crossed the line. >> he was also trying to pull my shirt off. i thought that he was going to rape me and i was struggling. at some point he gave up and he said "you're just a child," and he said, "i am the district attorney, no one will ever believe you." >> young girls can feel trapped. they can feel nobody is going to believe them so then teens feel that they can't say anything and they simply need to endure the sexual assault as it's happening

and for many years after when they're feeling ashamed and compromised. >> nelson's account the latest in a series of bombshell allegations against moore which began with a report in the "washington post" last thursday. >> the post was in alabama reporting a story related to supporters of roy moore when we heard these rumors that he had pursued teen-age girls decades ago. >> three of the women who ranged in age from 16 to 18 at the time allege moore asked them on dates. a fourth, leigh corfman, said she was molested by him when she was 14 years old. >> there were two times he took her to his house and on one of those times undressed her and undressed himself, touched her over her bra and underwear and had her touch him over his underwear. >> these attacks involve a minor, and they are completely false and untrue.

>> moore not only denied the allegations but painted them as a smear campaign, taking aim at his opponents. >> we do not intend to let the democrats or the established republicans or anybody else behind the story top this campaign. >> he laid the blame at what has become a familiar target, the media, posting this video on his facebook page. >> washington covered another attack on my reputation in a desperate attempt to stop my political campaign. >> even went on the offensive again his accusers. >> isn't it change th-- strange that after 40 years of constant investigation, people have waited till four weeks prior to the general election to bring a their complaints. it's not a coincidence. >> many women and girls will wait a lifetime or many years to report sexual assault. it is not uncommon to wait and

forget about reporting it because you feel like you're the only one. >> in a radio interview with fox news host sean hannity last friday, moore said he knew of two of the accusers who spoke to "the washington post" and that he didn't remember if he had pursued them. >> would it be unusual for you as a 32-year-old guy to have dated a woman as young as 17 or girls 16. >> not generally, no. and if i did, you know, i'm not going to dispute anything but i don't remember anything like that. >> despite the political blowback, some are standing by him. >> the media is the judge, jury and executioner. in judge moore's case, i'm going to support him. but if these allegations are true, obviously he should step aside. if we cannot prove this is just

based off of someone's words from over 40 years ago or 38, 40 years ago, then i think we should apply what we're expecting to happen to all american citizens is that we are innocent until proven guilty. >> tonight in alabama while no major republicans have withdrawn support for moore, several appear to be hesitating, including the governor. for now, though, with the special election just a month away, moore shows no signs of dropping out of this race. >> he is adamantly denying, he has his wife on his side on that. as long as that is the case, he may not be swayed by anyone's testimony. >> and coming up next here on "nightline," new charges in the alleged hazing death of a 19-year-old fraternity pledge at penn state.

afi sure had a lot on my mind. my 30-year marriage... ...my 3-month old business... plus...what if this happened again? i was given warfarin in the hospital, but wondered, was this the best treatment for me? so i made a point to talk to my doctor. he told me about eliquis. eliquis treats dvt and pe blood clots and reduces the risk of them happening again. not only does eliquis treat dvt and pe blood clots. eliquis also had significantly less major bleeding than the standard treatment. eliquis had both... ...and that turned around my thinking.

don't stop eliquis unless your doctor tells you to. eliquis can cause serious and in rare cases fatal bleeding. don't take eliquis if you have an artificial heart valve or abnormal bleeding. if you had a spinal injection while on eliquis call your doctor right away if you have tingling, numbness, or muscle weakness. while taking eliquis, you may bruise more easily... and it may take longer than usual for bleeding to stop. seek immediate medical care for sudden signs of bleeding, like unusual bruising. eliquis may increase your bleeding risk if you take certain medicines. tell your doctor about all planned medical or dental procedures. eliquis treats dvt and pe blood clots. plus had less major bleeding. both made eliquis right for me. ask your doctor if switching to eliquis is right for you.

new charges today in a case that could bring about significant rule changes in fraternity ple fraternity pledging. it involves an 19-year-old pledge overserved alcohol and eventually dying. authorities say they have new evidence, including intentionally deleted video. new information in the penn state death of tim piazza. >> we have new evidence. >> surveillance video that authorities say was destroyed is

now recovered by the fbi. >> this is the video that they clearly did not want seen. >> guess what, guys. now we know. >> they say the footage from the beta theta pi house show them giving the pledge 18 beers in an hour and 22 minutes. >> it's awful what a coordinated effort that this crew took upon themselves to get tim and the other pledges so drunk for the reason of becoming part of their organization. i am glad that the basement video was recovered and we finally know what went on down there. that was the whole defense argument, we don't know. >> piazza's parents reacting to the new charges in this interview. >> reporter: at this point, have you been able to watch that video or are you just not doing that? >> i think we're just not doing that. >> now new charges against a

dozen former fraternity bothers, bringing the total to 26. they say on that night, piazza and 26 other pledges took part in what they call the gauntlet. piazza suffered a catastrophic fall, 15 feet down a flight of stairs. the grand jury reports say no one called 911. instead, previously released video captured hours of piazza in distress, the injured college sophomore trying to get up and repeatedly falling over. four men are seen dragging his limb many bp body upstairs by s his face and pouring water over him. this member tried to get him the help he needed. >> i was saying we should take him to a hospital and call an ambulance, dial 911.

>> it's nice that he had good intentions at the time but i don't know why anybody didn't pick up a phone. >> instead of dialing 911, the report says the brothers were using their phone to search for the phrases "ifalling asleep after head injury" and cold feet and cold hands. >> what's going on today? >> ah, we have a friend that's unconscious. he hasn't moved, probably going to need an ambulance. >> back in may when i spoke to his parents, they said by the time they saw him in the intensive care unit, he was almost unrecognizable. >> he was all covered up with warming blankets. we were trying to find skin to touch. the nurses told me to tell him good-bye. it was hard.

that's what you think of when you close your eyes. >> it looked like he got hit by a car. he was in bad shape, he was on life support. he wasn't there. the nurse brought me in a room to see them and they broke it to me that he wasn't going to wake up ever. >> piazza died from his injuries the next day. medical experts estimate his blood alcohol content at the time of the fall was 0.4. during a preliminary hearing in july, prosecutors say they had evidence that members of the beta theta pi chapter had withheld key information, including these text messages allegedly, changed between the frat brothers. one reads "he looked [ expletive ] dead." another "i think we are [ expletive ], like beyond [ expletive ]." after this, i think we could get kicked off. >> i don't want to go to jail for this.

one brother allegedly urged another to delete a group message that included piazza so there would nobody evidence on tim's phone. another writing, "make sure the pledges keep quiet about last night and this situation." >> these fraternity guys thought that by erases text messages or erasing their searches on their internet browser that they would prevent law enforcement from finding that information, but the reality is that once a text message is sent, once an internet search is conducted, that information can't just disappear. >> prosecutors say the frat brothers thought they could make the basement videos disappear, too. they claimed the videos weren't working and police worked with the fbi to recover the missing video. that studio now charged with tampering with evidence. >> there was a text message

where nor individual had been talking with that person about deleting it. >> there's no question it was intentionally deleted. that will come out in the hearings. >> the d.a. said the discovery unravels the previous defense claim this was all social drinking. >> we know for a fact that no one else -- that tim was not getting his own drinks and that the brothers were continuing to furnish them. >> they are refiling voluntary manslaughter. all 14 men previously indicted have denied the charges. abc news reached out to all 12 of the new defendants. only one of them responded, denying any involvement. >> i think there's been a lot of questions at universities in the last several years about hazing and what it means and who's responsible. it's often more complex when you have young people, you have people drinking, stories change,

stories are not always reliable. >> despite the pain and the heartbreak, tim piazza's parents hope their son's story can help make hazing a thing of the past. >> talk to your children. tell them not to get involved in this nonsense. and if you're potentially one of the people that are about to get hazed, just walk away. have friends with you and make a pact and walk away. >> your life is too important to put it on the line for a brotherhood or a sisterhood. >> coming up next here on "nightline," the legendary gossip columnist liz smith dead at the age of 94. the sad change she said she saw in celebrity culture. >> announcer: abc news "nightline" brought to you by geico. she had so many children she had to buy lots of groceries. while she was shopping for organic fruits and veggies,
