>> at the end of the day he got heatstroke. 103 was his core temperature. >> reporter: trainees can quit any time they one. but mullen refused. "i'm not going to die. i'd rather die here. >> s.e.a.l.s need training, but not this kind of torture. >> reporter: as a result of kyle mullen's death, the s.e.a.l.s are increasing the number of medical observers and testing for performance-enhancing drugs. they have not made any changes in the training itself. norah? >> david martin, thank you. well, a breakthrough technology is helping people communicate by using their mind. that story in 60 seconds.

for more news download the cbs news app on your cell phone or connected tv. i'm wendy gillette, cbs news, new york. ♪ >> announcer: this is the "cbs overnight news." >> we want to begin tonight with that extraordinary just before midnight filing from the justice department where the government laid out its investigation in far more detail than ever before. the document is 36 pages long with 18 additional pages of attachments and includes this photo at the end of the filing, the final page showing several classified secret and top secret documents. one noteworthy point, none of the folders bear a label or stamp indicating they've been declassified as trump or his representatives have claimed. even some of the personnel and doj prosecutors on the case needed to get extra clearances to review some of that material.

in this filing, the government lays out an important timeline, saying it tried to get these documents without a search warrant multiple times. they allege donald trump has pushed a, quote, incomplete and inaccurate narrative in the recent court filings, and that's why we are getting this new information. cbs' robert costa joins us. good evening, robert. there is a lot of new details tonight. >> good evening, norah. there certainly are many new details here. stunning on how it shines a bright light on what was inside trump's home and gives us a look at the scope of this high profile investigation. the explosive legal document revealed for the first time ever photo evidence of some of the alleged highly classified documents seized from former president trump's florida home. the redacted fbi photograph shows classified cover sheet, some with "hcs" markings. that refers to intelligence derived from covert human sources. some of the documents were found in trump's so-called 45 office at mar-a-lago, a location

considered vulnerable by intelligence officials. >> the last thing you want to do is disclose those capabilities and the insights from them to our adversaries. >> reporter: the justice department has also laid out a case of possible obstruction by trump and his lawyers, asserting they had evidence that government records were likely concealed and removed from the storage room, and that efforts were likely taken to obstruct the government's investigation. back on june 3rd, two months before the search of mar-a-lago, trump's legal team told justice department officials that all sensitive documents had been returned. >> obstruction here according to the department of justice is that they were told false facts. they were told all the documents had been turned over when in fact their evidence they developed showed they hadn't been turned over. and when they executed a search warrant, it turned out they had not been turned over. >> reporter: responding today, trump slammed the fbi's handling of the search, and claimed he declassified documents at his home.

but in its filing, the government stated that trump's lawyers never asserted that trump had declassified the documents or asserted any claim of executive privilege. marc short, a long-time republican and adviser to vice president pence in the white house said trump made a mistake. >> president trump likely should not have been in possession of those documents. i don't think that's too far of a stretch for a rational person to say. >> reporter: some legal experts say that while the probe is ongoing, criminal charges could follow. >> an indictment on obstruction of justice absolutely possible. most cases an indictment for obstruction of justice will accompany a substantive criminal indictment, but a stand-alone obstruction of justice charge does happen. >> reporter: in the last few hours, sources close to trump told cbs news that they now see this as both a legal and political war and expect trump to be unbound in his efforts to galvanize his supporters and cast the justice department as political, all as federal agents continue to face increased

threats. norah? >> as the midterm approaches. robert costa, thanks very much. tonight donald trump is actually talking about that picture with top secret material on the floor of mar-a-lago. he is accusing the fbi of being, quote, very deceiving. cbs and justice correspondent jeff pegues is here. and jeff, taking evidence of in a photo like that, that's standard procedure at the fbi, is it not? >> it is. but the department of justice, they knew that this photo would have an impact. i mean, take a look at it. you have this evidence, some of it, most of it marked "top secret" sprawled out on the office floor of the former president at mar-a-lago. look at this ruler here, demonstrating the size of this document. and then the marker here, an evidence marker, the kind of evidence marker that you might see at a crime scene on a street somewhere. and cbs news has learned that there are a lot of pictures similar to this one in the investigative file. one question is were these documents mixed in with mr.

trump's personal property in an effort to conceal them? sources tell me that the department of justice believes the former president and his representatives have been less than truthful. a law enforcement source says they have been lying to us. when asked if the filing yesterday fully showed the government's evidence, the answer was clear. there is more to come. norah, department of justice officials say they don't discuss ongoing cases, but in this case, because the trump team asked for a special master, it really gave prosecutors an opening to show off evidence like that. >> very interesting. jeff pegues, thank you so much. well, now to jackson, mississippi and the latest details in the humanitarian water crisis facing nearly 200,000 people. president biden quickly approved an emergency declaration and ordered federal assistance for the state. cbs' janet shamlian reports again from there.

>> it's just all unfair, you know, to this community. >> reporter: jackson's population is 80% black. 25% live in poverty. the city, like many serving minorities, can't afford to fix this alone. mississippi is slated to receive $75 million for water issues from the recently passed infrastructure bill, but it could cost a billion dollars just to fix jackson. ayanna smith says she never drinks jackson's water, even aut ening all raining and stuff like this. >> reporter: this isnef water giveaways ross jacks henight.ionaar contributing to the effort to ease the long lines and get more water to people. the mayor has said water pressure should begin to resume tonight, and there are plans for a new pump to go in tomorrow. but norah, for the people who live here, that is a temporary fix. >> really tough conditions. janet shamlian, thank you.

generation of royals can't recapture her magic, a strange cocktail of glamour and vulnerability. this is kensington palace, diana's former home. and you can see the tributes that people have laid out in her honor. arguably, one of the biggest impacts she had on this country was to make the royal family a little bit more relaxed, a little more down to earth. perhaps even a bit more human. >> that was holly williams reporting. the "overnight news" is back in two minutes.

connected tv. i'm wendy gillette, cbs news, new york. ♪ the justice department argues in an historic detail filing that sensitive and top secret documents at donald trump's florida resort were hidden or moved on purpose, raising the possibility of an obstruction case. >> for the first time, we're seeing some of the top secret documents seized from the fbi's search of the former president's office at mar-a-lago. cbs' robert costa and jeff pegues have new reporting. triple-digit temperatures. the long heatwave roasting the west this labor day weekend. plus, the worsening water crisis in mississippi. cbs' janet shamlian is in jackson. >> no water is a struggle. navy s.e.a.l. death. a former yale football captain dies during hell week. tonight questions about the culture of brutality and drug use.

cbs' david martin spoke to kyle mullen's mother. >> it's like a sick hazing. it's not training. and the medical breakthrough. cbs' dr. jon lapook looks at new technology that could change lives. > this is science fiction. ♪ >> announcer: this is the "cbs overnight news." >> we want to begin tonight with that extraordinary just before midnight filing from the justice department where the government laid out its investigation in far more detail than ever before. the document is 36 pages long with 18 additional pages of attachments and includes this photo at the end of the filing, the final page showing several classified secret and top secret documents. one noteworthy point, none of the folders bear a label or stamp indicating they've been declassified as trump or his representatives claim.

the justice department says even some of the personnel and doj prosecutors on the case needed to get extra clearances to review some of that material. in this filing, the government lays out an important timeline, saying it tried to get these documents without a search warrant multiple times. they allege donald trump has pushed a, quote, incomplete and inaccurate narrative in the recent court filings, and that's why we are getting this new information. cbs' robert costa joins us. good evening, robert. there is a lot of new details tonight. >> good evening, norah. there certainly are many new details here. stunning on how it shines a bright light on what was inside trump's home and gives us a look at the scope of this high profile investigation. the explosive legal document revealed for the first time ever photo evidence of some of the alleged highly classified documents seized from former president trump's florida home. the redacted fbi photograph shows classified cover sheet, some with "hcs" markings. that refers to intelligence

derived from covert human sources. some of the documents were found in trump's so-called 45 office at mar-a-lago, a location considered vulnerable by intelligence officials. >> the last thing you want to do is disclose those capabilities and the insights from them to our adversaries. >> reporter: the justice department has also laid out a case of possible obstruction of the probe by trump and his lawyers, asserting they had evidence government records were likely concealed and removed from the storage room, and that efforts were likely taken to obstruct the government's investigation. back on june, two months before the search of mar-a-lago, trump's legal team told justice department officials that all sensitive documents had been returned. >> obstruction here according to the department of justice is that they were told false facts. they were told all the documents had been turned over when in fact their evidence they developed showed they hadn't been turned over. and when they executed a search warrant, it turned out they had not been turned over. >> reporter: responding today,

trump slammed the fbi's handling of the search, and claimed he declassified documents at his home. but in its filing, the government stated that trump's lawyers never asserted that trump had declassified the documents or asserted any claim of executive privilege. marc short, a long-time republican and adviser to vice president pence in the white house said trump made a mistake. >> president trump likely should not have been in possession of those documents. i don't think that's too far of a stretch for a rational person to say. >> reporter: some legal experts say while the probe is ongoing, criminal charges could follow. >> an indictment on obstruction of justice absolutely possible. most cases an indictment for obstruction of justice will accompany a substantive criminal indictment, but a stand-alone obstruction of justice charge does happen. >> reporter: in the last few hours, sources close to trump told cbs news that they now see this as both a legal and political war and expect trump to be unbound in his efforts to

galvanize his supporters and cast the justice department as political, all as federal agents continue to face increased threats. norah? >> as the midterm approaches. robert costa, thanks very much. tonight donald trump is actually talking about that picture with top secret material on the floor of mar-a-lago. he is accusing the fbi of being, quote, very deceiving. cbs and justice correspondent jeff pegues is here. and jeff, taking evidence of in a photo like that, that's standard procedure at the fbi, is it not? >> it is. but the department of justice, they knew that this photo would have an impact. i mean, take a look at it. you have this evidence, some of it, most of it marked "top secret" sprawled out on the office floor of the former president at mar-a-lago. look at this ruler here, demonstrating the size of this document. and then the marker here, an evidence marker, the kind of evidence marker that you might see at a crime scene on a street somewhere. and cbs news has learned that there are a lot of pictures

similar to this one in the investigative file. one question is were these documents mixed in with mr. trump's personal property in an effort to conceal them? sources tell me that the department of justice believes the former president and his representatives have been less than truthful. a law enforcement source says they have been lying to us. when asked if the filing yesterday fully showed the government's evidence, the answer was clear. there is more to come. norah, department of justice officials say they don't discuss ongoing cases, but in this case, because the trump team asked for a special master, it really gave prosecutors an opening to show off evidence like that. >> very interesting. jeff pegues, thank you so much. we want to turn now to the war in ukraine and fears of a chernobyl-style disaster at europe's largest nuclear power plant. a team of inspectors hope to reach the embattled site in a matter of hours on a mission to prevent a nuclear catastrophe.

>> he could barely breathe. and i was yelling at him. i asked him. are you in the hospital? are you in pain? do you have broken bones? no, ma, don't worry. i love you. >> reporter: she texted him. i need to know your condition. you did not sound good. >> he died hours later laying on the barrack floor. >> reporter: the cause of death was pneumonia, which his mother says was the result of submersion in the cold water off california. but a search of a car he shared with other trainees found performance-enhancing drugs, which he had told her about. >> said it would help them recover faster and get them through hell week. it was the only way possible to get through. >> reporter: 40 members of kyle mullen's class of 210 would-be s.e.a.l.s admitted taking banned substances, a warped testament to training which pushes young men to their absolute limits. >> that first day of that training, he was not given water all day. at the end of the day, he got
