Good evening and welcome. An extraordinary give and take in the u. S. Hours wrangling Supreme Court today, as the nine justices spent nearly three hours wrangling with lawyers over questions of when or whether a former american president is immune from federal prosecution over acts while taken in office. The questions raised during oral arguments are more than academic, but instead sit at the center of the special counsels criminal election interference case against former president trump, and whether a trial can happen before the november election. Mr. Trump claims absolute immunity from prosecution, something the court didnt seem inclined to go along with, yet conservatives on the court sharply questioned the special counsels position, as well. None of that stopping the new york hush money trial, which continued today for mr. Trump, as a key witness testified for a third day. Laura jarrett has details. Reporter tonight, the u. S. Supreme court weighing a monumental question that will decide whether the former president goes to trial for plotting to overturn the last election and win. I think that the Supreme Court has very important arguments before it today. Reporter mr. Trump hoping to persuade the justices to find him immune from federal charges. His lawyers arguing the office of the presidency would be completely hobbled without that protection. Without president ial immunity from criminal prosecution, there can be no presidency as we know it. Reporter the special counsels office indicted mr. Trump on conspiracy and obstruction charges last year, for his efforts to cling to power, accusing the likely gop nominee of pressuring State Officials to reverse the Election Results. Actions doj argues were for purely personal gain and cannot be shielded from prosecution. There is no immunity that is in the constitution unless this court creates it today. Reporter the conservatives expressing concern if future president s have no immunity for actions taken while in the white house. That could open the door to recrimination between political rivals. Will that not lead us into a cycle that destabilizes the functioning of our country as a democracy . Reporter the liberal justices troubled by the prospect of insulating president s from accountability, raising a series of dark hypotheticals to underscore the consequences of adopting mr. Trumps position. If a president sells Nuclear Secrets to a foreign adversary, is that immune . How about if a president orders the military to stage a coup . That sure sounds bad, doesnt it . Im trying to understand what the disincentive is from turning the oval office into, you know, the seat of Criminal Activity in this country. Reporter the fallout over efforts to subvert the Election Results in 2020 stretching beyond washington. In arizona, a grand jury indicted several members of mr. Trumps inner circle wednesday, accusing them of falsely awarding the statesump electors to Congress Electoral votes to mr. Trump, despite his lost to President Biden. The sending of phony slates of protrump electors to congress to disrupt the Election Certification on january 6th looming large at the High Court Today as well, as the justices look to determine the line between a political candidates actions taken for personal gain from a president s official conduct that could be immune from prosecution. Laura, we heard a lot today. What are the possible outcomes here . Reporter well, lester, there is any number of different scenarios that the Supreme Court could take here. It seems most likely based on the questioning that the justices will say the former president is not completely immune from all acts, but he might enjoy some limited immunity for some acts in which case theyre likely to send this case back down to the lower court to do some of that work, to figure out where the line is, lester. But of course that means more delays and it means this case is not going to trial by november. Lester . All r us off, thank you. And mr. Trumps first criminal trial resumed in new york with more telisher of the National Enquirer about that payment to an adult film star. Here is vaughn hillyard. Reporter on his third day on the stand, former National Enquirer publisher of david pecker told the jury he refused to catch and kill Stormy Daniels story about her relationship with then candidate donald trump. Pecker said he told his right hand man at the enquirer not to pay daniels the 120,000 she was seeking, because theyd already shelled out Tens Of Thousands of dollars to keep other stories about mr. Trump quiet. If anyone should buy it, pecker said, it should be donald trump and michael cohen, trumps former fixer. Pecker says when he told cohen, quote, he was upset and responded that the boss thats referring to trump would be furious with me. Pecker said today he believed mr. Trump or his company had paid daniels until cohen told him in December Of 2016 that he was the one who paid her. Prosecutors are seeking to prove mr. Trump doctored internal Business Records to cover up that payment. Pecker also Testified Trump was aghast when he saw Stormy Daniels on 60 minutes. Was It Hush Money to stay silent . Yes. Reporter pecker says trump called him. He said, we have an agreement with Stormy Daniels that she cannot mention any name. Trump later denied knowledge of the arrangement. On crossexamination, mr. Trumps lawyers challenging peckers credibility and business practices. At a Campaign Event earlier in the day, mr. Trump addressed the testimony of his longtime friend. Davids been very nice. A nice guy. Reporter did you give the payment to Stormy Daniels before the 2020 election . Pecker also testifying today about a payment the testimony of his longtime friend. David has been very to former playboy model Karen Mcdougal to keep her alleged affair with mr. Trump quiet. Pecker says he coordinated with cohen because he was concerned paying mcdougal could violate Campaign Finance law. So they worked up an agreement to pay for her contributions to magazines owned by american media, adding he believes trump was aware of the payment. The prosecution asking pecker, was your principle purpose to suppress her story so as not to influence the election . Pecker responding yes, it was. Vaughn, what did mr. Trumps lawyers focus on during david peckers Cross Examination . Reporter lester, for one, that donald trump was not the only celebrity he helped Squash Negative stories for, in exchange for good ones. But instead, that this was a mutually beneficialy here in new Relationship Dating back to the 90s, when donald trump was a celebrity here in new york city. Crossexamination will continue tomorrow. Lester . Vaughn hillyard, thank you. New protests flaring up across the country today as propalestinian demonstrations escalated, and more people were arrested. And with Graduation Season practically here, liz kreutz reports schools are making tough choices. We will not go reporter in an unprecedented move, the university of Southern California tonight canceling this years main commencement ceremony, attended by roughly 65,000 people, citing new Safety Measures put in place amid protests on campus. This stunning decision coming a day after nearly 100 protesters were arrested for trespassing after a contentious rally where propalestinian demonstrators clashed with police. Even if they have to cancel every single commencement, thats up to them. Reporter the tabassum c Schools Administration had already canceled the Graduation Speech for their propalestinian valedictorian asna tabassum, citing safety concerns. Coasttocoast protests growing from George Washington university to northeastern to emory in atlanta, where police in riot gear today clashed with demonstrators. Law enforcement appearing to use zip ties to restrain the protesters, even tasing one person. At columbia, the epicenter of the protests, those camping out given a deadline to disperse by 4 00 a. M. If not, the University Says we will have to consider alternative options for clearing the area. And these protests are now spreading here in california as well. Here at ucla, students have begun gathering, pitching tents in the heart of campus. Many of these students calling on the university to divest from israel. Tonight, these rising tensions igniting a debate about free speech versus hate speech on college campuses. At usc, professor Brittany Friedman criticizing the university for escalating what she said have been peaceful protests. You believe these students First Amendment rights are being violated . Absolutely, absolutely. They are criticizing a nation state for their actions in war, not criticizing a faith, a faith that is very close to me. Reporter but some jewish students say they feel the demonstrations have crossed the line. I dont believe that advocating for the rights of the Palestinian People are inherently antisemitic. But some of these chants and some of the ways in which that they attribute and target jewish students, that is antisemitic. And liz joins us now from ucla. Whats the scene there, liz . Reporter well, le lest, there was a moment where things got pretty contentious here. Campus security has now showed up, and these protests, at this encampment, they say they plan to stay here until the university meets their demands. Lester . Liz kreutz in los angeles, thank you. Now to that startling reversal today in that new york rape case that sent former film mogul Harvey Weinstein to prison. The States Top Court overturning his conviction. Here is kate snow. Reporter for the more than 100 accusers of Harvey Weinstein, it was a shock. This today is an act of institutional betrayal. Reporter in a 43 decision, the New York Court Of AppealsFinding Weinstein is entitled to a new trial. His spokesperson speaking to nbcs chloe melas. What he did might have been insensitive, might have been unethical, but it wasnt a crime. In order to bring it back, theyre going to have to find witnesses to come forward with actual crimes. Reporter weinstein was charged with crimes in new york involving three women and convicted in 2020 of rape and sexual assault. But that trial also included testimony from three other women who made allegations that never led to charges. Today, the majority in the Court Of Appeals Concluding The Trial court made egregious errors, erroneously admitting that testimony, calling it unnecessary. The jury was able to look at that and probably infer that he was guilty in the past. So he must be guilty now. Reporter and thats what this higher court said cant be allowed . Thats right. Reporter the State Court Of Appeals also said the trial court abused its discretion when it said weinstein could be crossexamined about those other three women. And even if he denied them, just the fact of being accused of them could allow the jury to infer his guilt based on prior behavior. Reporter he then decided not to testify. One of those women was dawn dunning. Today, she said, people have asked me if i regret having testified, was this all for naught, and my answer is a resounding no. We spoke with other weinstein accusers not involved in the trial. All of the fear and the panic and the confusion from the original trauma comes back. Im deeply concerned. Its a setback for justice for survivors. Reporter in a dissenting opinion, three justices wrote, men who serially sexually exploit their power over women will reap the benefit of todays decision. Weve already heard this refrain about me too has gone too far. I think theres going to be some people out there thinking, oh, good. So, now weve regressed the balance. And i dont think me too ever went far enough. So kate, what happens now . So, the manhattan district attorneys office, lester, says they will do everything in their power to retry the case. Weinsteins representative says for now he will remain in new york. And remember, weinstein is appealing a 16year sentence for rape in california. His l. A. Attorney tonight says the new york decision has a Significant Impact on that pending appeal, saying the l. A. Trial judge, quote, made the same errors as the new york trial court. Lester . All right.
