This is the cbs evening news. Mason good evening. Im Anthony Mason. It was all very familiar. Millions of americans glued to their televisions, waiting to hear the fate of o. J. Simpson. But it was two decades later, two decades after simpson was acquitted of murder charges in the trial of the century. Today the question was whether simpson would be granted parole after serving nine years in a nevada prison in an unrelated case, an arm robbery in las vegas. Heres John Blackstone with the verdict. Mr. Simpson, i do vote to grant parole when eligible, and that will conclude this hearing. Thank you. Reporter his relief was obvious. O. J. Simpson, now 70 years old, would soon be free on parole. It was a serious crime and there was no excuse for it. Reporter the hearing Via Video Conference lasted more than an hour as commissioners asked simpson how prison had changed him. Are you humbled by this incarceration . Oh, yeah. Sure. Reporter while expressing regret, he insisted it was others who decided to bring guns the day in las vegas they robbed two memorabilia dealers of items simpson believed had been stolen from him. I am no danger to pull a gun on anybody. You know, i never have in my life. Ive never been accuse of it in my life. Reporter one of the dealers robbed that day, bruce fromong, told the parole board simpson served enough time. This is a good man. He made a mistake. He truly is remorseful. Reporter simpsons oldest daughter arnelle. We just want him to come home so we can move forward for us. Quietly. Im in the a guy who lived a criminal life. You know, im a pretty straight shooter. Reporter but hanging over the hearing was the accusation in 1994 that simpson had brutally murdered his exwife nicole and her friend ron goldman. Ive always thought ive been pretty good with people, and i basically. Its been a conflictfree life. Reporter one of the least selfaware moments that i have ever heard. Reporter law professor laurie levinson. There are a lot of things you might say about o. J. Simpson, and you might even say that acquittal was fair, but to say that hes led a conflictfree life, i dont think so. Reporter simpson will remain in prison until at least october 1st. He said he wants the return to florida where he lived before his nevada conviction, but parole officials in both states must agree. Anthony . Mason John Blackstone outside the prison in lovelock, nevada. President trump has had a very public falling out with attorney general jeff sessions. The first member of the senate to endorse his run for the white house. Heres chip reid. Reporter President Trump was once enamored with attorney general jeff sessions. I am pleased to endorse donald trump for the presidency of the united states. Reporter but not anymore. In an extraordinarily candid interview with the New York Times, the president gave sessions an angry public scolding for recusing himself from the russia investigation. Sessions should have never recused himself, and if he was going to recuse himself, he should have told me before he took the job, and i would have picked somebody else. Its extremely unfair, and thats a mild word, to the president. Reporter sessions was asked today if hes considering resigning. I have the honor of serving as attorney general, and i plan to continue to do so as long as that is appropriate. Reporter the president also criticized special Counsel Robert Mueller for accepting the job as head of the russia investigation just one day after interviewing with mr. Trump to be f. B. I. Director. What the hell is this all about . You talk about conflicts, he was interviewing for the job. Reporter and he again unleashed his fury at former f. B. I. Director james comey. In june Comey Told Congress that mr. Trump instructed other advisers the leave the oval office, then asked comey to drop the investigation of former National Security adviser michael flynn. But the president told the times he did not shoo people out of the room. I dont remember even talking to him about any of this stuff. His testimony is loaded up with lies. Reporter in a long, rambling interview, the president also reminisced about his recent trip to paris and to napoleons tomb, and he gave a History Lesson about how napoleon and hitler lost major battles against russia because their armies froze to death. The president seemed fascinated, mentioning it more than once, that french president Emmanuel Macron has a fondness for holding hands. People dont realize he loves said, and thats good as far as that goes. A white house spokesperson said today that, yes, President Trump is disappointed in attorney general sessions, but he has not lost confidence in him and has no plans to fire him. Anthony . Mason chip reid at the white house, thank you, chip. The special counsel is now looking into the trump Business Empire in the investigation of russian meddling in the u. S. Election and whether anyone in the Trump Campaign was involved. Heres julianna goldman. Reporter in that New York Times interview, President Trump had a warning for special Counsel Robert Mueller. Investigating his finances and his familys finances would cross a red line. I think thats a violation, he said. This is about russia. But investigators are already examining the financial dealings of mr. Trump and his associates, not limiting themselves to possible collusion with russia in the 2016 election. Mr. Trumps business ties to russia go back decades. The special counsels mandate is broad and allows him to investigate any matters that arose or may arise directly from the investigation. Cbs news has confirmed mueller is also looking into the business dealings of former Trump Campaign chairman paul manafort, an investigation initiated by prosecutors in the Southern District of new york. Speaking for myself, i own nothing in russia. I have no loans in russia. I dont have any deals in russia. Reporter the head of the public corruption unit at the Southern District, andrew goldstein, recently joined muellers team. He oversaw the manafort probe. Prosecutor Andrew Weissmann is another team member. His expertise, financial fraud. Weissmann helped lead the federal task force that investigated corruption at energy giant enron. With multiple and overlapping probes from the department of justice to capitol hill, some investigators are also looking into purchases in units in trump property. The Senate Intelligence committee is pouring through thousands of pages of financial records from a unit in the Treasury Department that fights money lawbdering. In a New York Times interview, the president also said, its possible theres a condo or something. I sell a lot of condo units and somebody from russia buys a condo, who knows. He also said he doesnt make money from russia. Anthony . Mason julianna goldman, thanks. We turn now to john dickerson, our chief washington correspondent and anchor of face the nation. John, these are pretty unusual remarks for a president to make about his attorney general, arent they . What do you make of them . What, what makes these comments so unusual is the president is not criticizing a policy decision an attorney general made. Hes making claims about the attorney generals character. He says it was unfair that the attorney general didnt tell him that he would recuse himself from the russia investigation. Now, the attorney general deals with right and wrong, so questioning his fairness is different than if you were questioning another cabinet official. And the president also didnt seem to believe attorney general sessions testimony about why he was not immediately forthcoming about his meetings with the russian ambassador. The president said sessions was asked, simple questions and that his answers should have been simple answers but they werent. Mason this interview comes as we mark six months now of the trump administration. Where do you think this fits in in the scope of his presidency . Well, at six months in, President Trump in this interview is the same person as candidate donald trump. He is free wheeling, full of hyperbole, there are inaccuracies, and hes saying exactly what is on his mind, even if it breaks the normal rules. Whether those rules are about criticizing an attorney general or criticizing special counsel mueller, even though that criticism could be considered interference in the investigation, which is one of the things the president is being investigated for. And all of this to the New York Times, which the president has criticized regularly. The office has not changed the man. Mason john dickerson, thank you very much, john. The Treasury Department fined exxonmobil 2 million today for violating u. S. Sanctions in 2014 when it signed contracts with a blacklisted russian oil executive. Rex tillerson was exxons c. E. O. At the time and called sanctions ineffective. Now secretary of state tillerson supports keeping them in place until russia gives back crimea. John mccain, the sixterm senator from arizona, 2008 republican president ial candidate, and vietnam war hero is fighting the biggest battle of his life. The enemy, an aggressive form of brain cancer. Heres chief Congressional Correspondent nancy cordes. Were rooting for you, dear friend. If anybody is going the bet a disease like this, its going to be john mccain. Reporter senator mccain put up with the emotion for about 12 hours. The last straw was this tribute from his friend Lindsey Graham. I cant think of anything ive done since 1999 politically, in many ways personally that was worth doing without john. Reporter mccain recovering in phoenix intervened. He has called me three times this morning. No more whoa is me, lindsey. He is yelling at me to buck up. Reporter i greatly appreciate the outpouring of support. Unfortunately for my sparring partners in washington, ill be back soon. Tough talk from man who survived five and a half years as a prisoner of war in vietnam and has spent three decades honing a takenoprisoners style on capitol hill. Its really embarrassing to hear you Say Something like that was waste of time because they had no information. Its unfair. Its bizarro. Reporter that Straight Talk has endeared him to both sides. Many senators pointed today to this moment in his run against thensenator obama. Hes an arab. No, maam, hes a decent family man. He said, im feeling good. I may have some chemo to get through. Reporter arizonas junior senator jeff flake spoke to mccain last night. John mccain is a tough guy. This is a very tough form of cancer. It is. He knows that. His family certainly knows that. Reporter mccain has experienced battling cancer. He had four melanomas removed between 1993 and 2002. And anthony, were told it was Lindsey Graham who noticed that mccain seems run down lately and urged him to go get checked. Mason nancy cordes at the capitol. Thank you, nancy. Joining us now, our chief medical correspondent dr. Jon lapook. Jon, what exactly is the senator up against here . Reporter anthony, the problem is that glioblastoma is a really rough tumor to treat, and what happens is even though you think youre taking out the tumor and it look like you have, microscopically, its already spread to other parts of the brain, so it tends to come back, and, in fact, the median survival is only about 15 months. 10 of people live five years or longer. This is the same cancer that killed senator ted kennedy. Mason what are the Treatment Options for the senator then . Reporter well, he had surgery. Then hes going to get chemotherapy and radiation. After this there are exciting new possibilities, one adresses the fact that cancer tends to hide from the immune system. It cloaks itself in a check of invisibility. The idea is to strip away that cloak. At duke university, theyre taking inactivateed polio virus and injecting it directly into the cancer to stimulate the immune system to come and kill it. Theyre having some really interesting results from that. Mason so ive heard getting medicine into the brain can be very difficult, though. Reporter thats right. Its called the bloodbrain barrier. Its hard for drugs to get in. One really interesting approach is to use nanoparticles. You put the medication inside those and use it to sneak into the brain, and then it gets released and hopefully will fight the cancer, but at the end of the day, this is a tough cancer. The senator is certainly in for a big fight, and we need a ton more research. Mason all right. Dr. Jon lapook, thank you.
