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. i've 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: simpson's oldest daughter arnelle. >> we just want him to come home so we can move forward for us. quietly. >> i'm in the a guy who lived a criminal life. you know, i'm a pretty straight shooter. >> reporter: but hanging over the hearing was the accusation in 1994 that simpson had brutally murdered his ex-wife nicole and her friend ron goldman. >> i've always thought i've been pretty good with

basically... it's been a conflict-free life. >> reporter: one of the least self-aware 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 he's led a conflict-free life, i don't 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. here's chip reid. >> reporter: president trump was once enamored with attorney general jeff sessions. >> i am pleased to endorse donald trump for the

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. it's extremely unfair, and that's a mild word, to the president. >> reporter: sessions was asked today if he's 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 jamesom

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 don't 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 napoleon's 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. said, "and that's 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

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. here's julianna goldman. >> reporter: in that "new york times" interview, president trump had a warning for special counsel robert mueller. investigating his finances and his family's finances would cross a red line. "i think that's 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. trump's business ties to russia go back decades. the special counsel's 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

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 don't have any deals in russia. >> reporter: the head of the public corruption unit at the southern district, andrew goldstein, recently joined mueller's 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, "it's possible there's a condo or something. i sell a lot of condo units and somebody from russia buys

condo, who knows." he also said he doesn't 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, aren't 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. he's making claims about the attorney general's character. he says it was "unfair" that the attorney general didn't 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 didn't 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 weren't." >> mason: this interview me

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 he's 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 exxon-mobil $2 million today for violating u.s. sanctions in 2014 when it signed contracts with a black-listed russian oil executive. rex tillerson was exxon's c.e.o. at the time and called

ineffective. now secretary of state tillerson supports keeping them in place until russia gives back crimea. john mccain, the six-term senator from arizona, 2008 republican presidential candidate, and vietnam war hero is fighting the biggest battle of his life. the enemy, an aggressive form of brain cancer. here's chief congressional correspondent nancy cordes. >> we're rooting for you, dear friend. > if anybody is going the bet a disease like this, it's 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 can't think of anything i've 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

he is yelling at me to buck up. >> reporter: "i greatly appreciate the outpouring of support. unfortunately for my sparring partners in washington, i'll 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 take-no-prisoners style on capitol hill. >> it's really embarrassing to hear you say something like that was waste of time because they had no information. it's unfair. it's bizarro. >> reporter: that straight talk has endeared him to both sides. many senators pointed today to this moment in his run against then-senator obama. >> he's an arab. >> no, ma'am, he's a decent family man. >> he said, i'm feeling good. i may have some chemo to get through. >> reporter: arizona's junior senator jeff flake spoke to mccain last night. john mccain is a tough guy. this is a very tough form

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, we're 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 you're taking out the tumor and it look like you have, microscopically, it's 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 he's going to get chemotherapy and radiation. after this there are exciting

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, they're taking inactivateed polio virus and injecting it directly into the cancer to stimulate the immune system to come and kill it. they're having some really interesting results from that. >> mason: so i've heard getting medicine into the brain can be very difficult, though. >> reporter: that's right. it's called the blood-brain barrier. it's 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. late today the minneapolis police chief spoke for the first time about the fatal police shooting of a yoga instructor from australia. the chief was critical of the officer's actions. jamie yuccs

jamie? >> reporter: minneapolis police chief janea said justine did not have to die. justine damond was shot to death by minneapolis police officer mohamed noor. when she walked up to the squad car at one point after dialing 911 twice thinking that she was reporting a supposed rape behind her home. now, the chief said she talked to justine damond's fianceée don just this morning, and he expressed to her that people are now scared to call 911. she said the department does need to regain the community's trust at this point. and she also reassured her family that she will do everything in her power to make sure justice served for justine. the officer and his partner, matthew harrity, did not have their body cameras rolling at the time. this is an important piece for many in this community. the they are wondering why this happened. the chief understands th.

officer noor has not given a statement yet in the independent investigation, anthony, and we did learn the police chief spoke for the first time today because she was on a backpacking trip until yesterday. >> mason: jamie yuccas with breaking news in minneapolis. thank you. coming up next on the "cbs evening news," it's full speed ahead for self-driving cars. but federal laws are lagging behind. and later, a young boy's ancient discovery. steve was born to move. over the course of 9 days he walks 26.2 miles,

its roads, replacing raised lane markers with six-inch-thick solid lines. they're easier for self-driving cars to see. what's not ready are the rules. scott keogh from audi. >> i think we need definitions. we need the government and the states to set laws that are united and unified around. this and there needs to be a little less p.t. barnumism where everyone is throwing around these terms. >> reporter: right now only 23 states and the district of columbia have laws on the books regarding self-driving cars. >> as this technology gets out on the road, we want the make sure that it is safe, that is truly is ready for prime time. >> the concept behind this bill is to try to create some certainty, some clarity, so people know what those rules are going to be. >> reporter: that could happen in the coming days. republican senator john thune and democrat gary peters plan to present rare bipartisan legislation setting standards for safety, cyber security, and guidelines to determine accident liability if no one is driving. do you feel real deadline pressure to get this done? >> it's only matter of time

horizon is coming very quickly at us. i think we have to be prepared for that. >> hopefully we can all get around the fact that this is incredibly exciting technology that will save literally tens of thousands of lives. >> reporter: and they believe it will this that because self-driving cars should eliminate one of the leading factors in crash, human error. anthony? >> mason: kris van cleave in washington. thanks. when we come back, a dusty old bag sells for an astronomical price. and you're talking to your rheumatologist about a medication... ...this is humira. this is humira helping to relieve my pain... ...and protect my joints from further damage. humira has been clinically studied for over 18 years. humira works by targeting and helping to... ...block a specific source... ...of inflammation that contributes to ra symptoms. it's proven to help relieve pain and... ...stop further joint damage in many adults. humira can lower your ability to fight infections, including tuberculosis. serious, sometimes fatal infections and cancers,
