inside the unit. >> so we narrowly escaped nuclear disaster? >> i would say that we were not far. not far. >> reporter: the nuclear plant was captured by russia in march. but is still operated by ukrainian technicians. and recent video from inside the plant shows russian military vehicles parked near reactors, raising the risk of accidental fires. it's been half a year since russia did the unthinkable and invaded ukraine. a presidential adviser says while they are grateful for all the military aid they received, billions more is needed in help weapons in order to win this war. >> this is artillery war. that is why, in artillery war, we need more ammunition. our request to u.s. government and national partners, please provide more military support for ukraine. >> reporter: six months on, and this war is far from over, with

no clear end game in sight. >> deborah, that is such a remarkable assessment considering how long this war has raged. now, inspectors with the u.n.'s iaea intend to deploy a team to the nuclear plant, but rea realistically, how soon is that possible? >> reporter: it could be early next week, but inspectors have been pushing to inspec that site for some time now. ukraine wants them to not only visit but create a permanent demilitarized zone there, errol. >> debora patta, thank you. tonight, new scrutiny of president trump's actions surrounding those highly classified documents recovered from his mar-a-lago resort. >> reporter: errol, cbs news has learned intelligence officials have begun a review to see if the nation's security has been

affected. it's the latest fallout of those classified materials at the florida resort. less than three weeks after the fbi searched former president trump's sprawling florida home, the office of the director of national intelligence is preparing a review of the items recovered. that's according to a letter from the director to congressional leaders obtained by cbs news. on friday, a federal court in florida released the affidavit submitted by agents to obtain a search warrant for the grounds earlier this month. the affidavit said 15 boxes of records returned from mar-a-lago this year included 184 documents with classification markings including 67 marked confidential, 92 as secret. in a written statement saturday, the chairs of the house intelligence and oversight committees said there is concern human sources were endangered. >> nobody, nobody in this country is above the law, whether they're president, former president, or anybody

else. >> reporter: in a social media post, the former president criticized the heavy redactions in the affidavit. the justice department says the redactions protect witnesses and investigative leads. >> they obviously don't want to be identified, obviously because of the level of threats. they're concerned for their welfare, and rightfully so. >> reporter: meanwhile, in a weekend legal filing, the former president has asked a judge to block the justice department from reviewing the materials in those retrieved boxes until an independent special master do so first. >> scott, thank you. today, in austin, texas, parents who lost loved ones in the uvalde school shooting are

>> reporter: apollo engineers put man on the moon using paltry technology. artemis' mission control looks a little different. >> how hurtful to the program would it be if it doesn't go right? >> i can't tell you that, i don't know. but it conceivably could end the program. i hope we don't have to worry about that. that's my goal. >> reporter: artemis ii would be a crude fly-by of the moon. artemis iii would include an astronaut of color and a woman still to be named. astronaut nicole mann admits she looks at the moon differently these days. >> especially when your 10-year-old says, mom, do you think you'll walk on that one day? i say, i hope so, son. >> reporter: but first things first. before future moon landings, before talk of living on mars,

this test flight has to go out. it will be nasa's reality check of how far artemis has come and how far it still has to go. errol? >> mark strassmann, thank you. now to a moonshot of sorts by california. this week the state accelerated moves to ban sales of new gas powered vehicles by 2035. cbs's tom waite is in l.a. tonight. >> reporter: ev sales in california have doubled in the last two years. but going all electric may not be a smooth ride. california wants to put engines like this in the rearview mirror. the state will phase out sales of air polluting gas powered cars, trucks, and suvs by 2035. >> i think california is leading the way. i hope they'll manage to do this. >> reporter: the regulation to help fight climate change also requires that within four years, 35% of all new cars sold to be

battery or hydrogen powered. but there are roadblocks. the average price of an electric vehicle is $66,000. and then there's the infrastructure issues. >> the grid does not currently have the capability to add millions of battery, electric, or even fuel cell electric vehicles today. >> reporter: to help fix that the state wants to install 250,000 charging stations by 2025. right now there are fewer than 80,000. automakers, already struggling with supply chain shortages, will need to ramp up production. california isn't banning gas powered cars. people can still drive them and even sell them as used cars. errol? >> thank you, tom. tonight, canadian police are investigating a theft that's captured the attention of art lovers worldwide. one newspaper compares this to the louvre losing the mona lisa. cbs's michael george is on the case. >> reporter: this landmark hotel
