after leaving the white house today, president trump tweeted he could have ended the whole witch hunt and fired everyone, including mueller, if he wanted to. he also pointed out his decision not to use executive privilege to withhold parts of the report. jeff? >> weija, thank you very much. jonathan turley is a law professional at george washington university. always good to have you here, professor. >> thank you. >> 448 pages. who can claim victory? >> well, it depends how you define victory. the president defines victory as being unindicted an unimpeached. that's not a very appealing slogan, three years, no indictments. it doesn't exactly appeal to most politicians because in the report, he comes across as rather unhinged and obsessive, but not necessarily obstructive. and so how that plays out for either the president or the

democrats, we'll have to see. >> are you surprised the president did not exert executive privilege? >> i am. i think you have to acknowledge that that was a commendable decision. i have not seen a report of this kind with this type of waiver of executive privilege. it is a commendable decision to release this. he could have tied this up in court for years. >> robert mueller's likely testimony coming up here. what does that mean? does that change anything? >> well, because of the waiver of executive privilege. >> right. >> this is going to be like a free-range prosecutor. he can actually go into a lot, more than we usually see, and they're going to press him on some of these details, you know, particularly the fact that the president wanted to fire him. so you're left with the zen-like question. if the president orders an obstructive act and nobody listens, is it still obstruction. >> and this is don mcgahn, who is refusing it or almost resigned. in the end, is don mcgahn the key figure in all this? >> he comes across pretty good.

i mean, he comes across like publicus publicana. he refuses multiple basic orders from a sitting president, even saying that he went back to his office to clear out his stuff. i mean, this was an amazing historical moment, and he comes across quite well in it. >> remarkable. jonathan turley, thank you very much. >> thank you, jeff. still ahead tonight, violent storms in the south. what we've learned about north korea's latest weapons test, but up next, lessons from five columbine survivors.

saturday marks 20 years since the columbine massacre in colorado. two teenagers murdered, 12 schoolmates against a teacher and wounded 20 others. we brought together five survivors, each with their own y an eh thr own powerful lesson to pass on today. >> reporter: on that day in 1999, craig scott's sister rachel was the first person killed. >> hi, how you? good to see you. >> reporter: craig is seeing amanda stair for the first time since evacuating the school 20 years ago. >> doing okay? >> yeah. >> reporter: heather martin

formed the rebels project, a group that goes to the scene of mass shootings to assist. michelle wheeler now teaches middle school english in the district and has never spoken publicly about that day. frank deangelis was the principal. he continued to serve in the job for another 15 years, a promise to see every student who was in the system at the time of the shooting through graduation. >> a show of hands, how many of you think about it every day? all of you. >> every morning when i wake up, as soon as i get out of bed, i recite the names of my beloved 13. >> reporter: how many of you, show of hands, still ask why? none of you. why is that? >> we've all been there. wealt that point where we're just angry at the world. >> i also think it's a question that can never be answered. we don't know why they did what they did. >> reporter: so you stopped trying to wonder? >> well, i mean, i've forgiven them.way 20th.

ulere'nothing i would get out of knowing why. >> reporter: michelle, you haven't spoken about this publicly. >> no. >> reporter: since. >> right. >> reporter: you have a 13-year-old. >> uh-huh. >> reporter: how does that impact the way you raised her? >> i started telling her about the shooting when she was 5 and going into kindergarten, and i started very developmentally appropriate, just saying mommy is sad that her friends are in heaven. and then as she got older, i started to tell her a little bit more. the hardest day of my life was sending her to kindergarten. i ended up in mr. frank deangelis's office in tears. i had no idea what i was doing, why i was letting her go. and every day still is a struggle, you know. every day i make sure i say i excited when she gets back in my car at the end of the day. >> reporter: do you think where she can get out places, exits?

>> we'll be in the doctor's ofc somewhere, and i'll say show me five places where you'll hide, because it could happen anywhere, and i want her to be prepared. and i think it makes me feel prepared. >> reporter: while michelle raises her daughter and teaches in the district, heather frequently travels outside it. >> the rebel project, we really focus in long-term because, you know, after an event, all the help in the world is focused on that one area, and it's really after the cameras go away that people start to feel that isolation and start to feel that loneliness. so our outreach doesn't start until, you know, sometimes months after the event. >> reporter: do you still feel the isolation and the loneliness? >> i don't feel the isolation anymore. i know i'm not alone. >> reporter: craig scott fd a gu teaches kids about respect. he's had kids acknowledge terrible thoughts. one even hampbded him a hit list. >> reporter: he handed you a hit list? >> yeah. over the years, my family and i, we've seen over a dozen

documented school shootings prevented from sharing, really, the story of my sister. >> reporter: what are you trying to tell kids these days? >> i meet so many kids that are feeling disconnected or don't feel they're valuable. when i learned about the shooters at columbine, i saw in their journals a real self-hatred, that they didn't value themselves. and if you're to ask me the biggest reason that columbine happened, it wasn't bullying at our school. it wasn't the medication they were on. it wasn't the lack of gun control. it wasn't that our school was a bad place or bad parenting. the biggest reason i tell kids that columbine happened was that the shooters focused on everything that was negative in this world. >> reporter: if there is one thing you want people tha repre from parkland and santa fe and sandy hook, i said columbine represents hope. and even though the road's going to be tough, it's going to be a tough journey, and you're going to be kicked down, you got to

get back up. and we're all there, and we're all part of this club, and we can all help each other. but i truly believe that the columbine community is stronger today than what it was almost 20 years ago, and we provide hope for others. >> and we want to thank everyone in littleton for spending time with us. with us. still ahead here tonight, ok i'll admit. i didn't keep my place as clean as i would like 'cuz i'm way too busy. who's got the time to chase around down dirt, dust and hair? so now, i use heavy duty swiffer sweeper and dusters. for hard-to-reach places, duster makes it easy to clean. it captures dust in one swipe. ha! gotcha! and sweeper heavy duty cloths lock away twice as much dirt and dust. it gets stuff deep in the grooves other tools can miss. y'know what? my place... is a lot cleaner now. stop cleaning. start swiffering.

the military bid farewell today to an american hero who gave his country hope when it was needed most. here's david martin. >> reporter:77 years ago to the day, doolittle's raiders took off on one of the most daring military operations ever. 16 bomb owners a one-way mission to japan. >> they bet big, and it worked because nobody thought such an attack was even possible. >> reporter: dick cole was the copilot of the lead plane, and the last survivor of the 80 men who struck back at japan at a time when america was still reeling from the attack on pearl harbor. after dropping their bombs on tokyo, cole and his crew bailed out over china as their plane

ran out of fuel and crashed. he lived to be 103, and as age whittled down their number, the surviving raiders decided to hold their last public reunion in 2013. >> all good things have to come to an end. >> reporter: they played to a packed house, and people stood in line to shake dick cole's hand. >> i had no idea you guys were such a big deal. >> we didn't either. >> reporter: today in a hangar at an air force base in texas, dick cole packed the house one last time. david martin, cbs news. >> that is the "overnight news" for this friday. for some of you, the news k f the morning news and "cbs this morning." from the broadcast center in new york city, i'm jeff glor.

this is the "cbs overnight news." >> welcome to the "overnight news." i'm don dahler. all of washington is in spin mode after the release of the long-awaited mueller report. president trump and his allies insist the report clears him of any wrongdoing, and moscow's effort to influence the 2016 presidential election. but the reports also details a long list of contacts between president trump's associates and russians, and it recounts numerous instances where the president attempted to block the investigation. the report itself has long sections blacked out. congress plans to subpoena the full report along with the

underlying investigative documents. william barr is already scheduled to testify on capitol hill, and democrats also want to hear from special counsel robert mueller himself. paula reid begins our coverage. >> i'm having a good day too. it was called no collusion, no obstruction. >> reporter: president trump took a victory lap today as congress and the public finally got to read the redacted mueller report. the much anticipated document was delivered to lawmakers around 11:00 a.m. on compact discs, and shortly after that posted online where anyone was able to dive in to the more than 400 page report 22 months in the making. on the question of obstruction, attorney general william barr said special counsel robert mueller uncovered evidence mr. trump was at least thinking about interfering in the probe. >> the report recounts ten episodes involving the president and discusses his potential legal theories for connecting

those elements to an obstruction offense. >> the report states the president's efforts to influence the investigation were mostly unsuccessful, but that is largely because the persons who surrounded the president declined to carry out orders or accede to his requests. some of those requests were directed at former white house counsel don mcgahn. the report states in june 2017, the president called mcgahn twice and told him to have the special counsel fired. mcgahn refused and even considered resigning. the report also reveals the president's reaction when then attorney general jeff sessions told him about mueller's appointment. according to sessions' former chief of staff, the president slumped in his chair and said, "oh my god, this is terrible, this is the end of my presidency. i'm f'd. everyone tells me if you get one of these independent counsels, it ruins your presidency. it takes years and years and i won't be able to do anything. this is the worst thing that ever happened to me."

the report says mueller's team struggled with the legal precedents for charging a sitting president with obstruction, calling them difficult issues. but mueller reports to barr, and the attorney general decided there was not sufficient evidence of a crime. barr said the president took no act that impeded the investigation and explained some of mr. trump's controversial statements this way. >> there is substantial evidence to show that the president was frustrated and angered by his sincere belief that the investigation was undermining his presidency. >> reporter: the report includes the president's answers to written questions, but reveals the special counsel found those inadequate. "we considered whether to issue a subpoena for his testimony," the report says, but citing potentially lengthy constitutional litigation with resulting delay, the special counsel did not move forward. on the issue of russian collusion, the report says the investigation uncovered multiple links between trump campaign

officials and individuals tied to the russian government, and in some instances, the campaign was receptive to the offer of help from the russians. of special interest was the june 2016 trump tower meeting attended by the president's son donald trump jr, son-in-law jared kushner, campaign chairman paul manafort, and a russian lawyer promising dirt on hillary clinton. mueller's team concluded it would unlikely be able to prove beyond a reasonable doubt that the meeting participants had general knowledge that their conduct was unlawful. in the end, the special counsel did not establish that the campaign coordinated or conspired with the russian government in its election interference. >> we now know that the russian operatives who perpetrated these schemes did not have the cooperation of president trump or the trump campaign or the knowing assistance of any other american, for that matter.

>> at the press conference earlier today, before anyone had actually seen the report, attorney general william barr denied that mueller had left this question of to congress, but in the actual report, mueller acknowledges that congress can determine if the president's actions cute a violation of the constitution, and he's clearly laid out a road map in his report for any lawmaker who would like to pursue an investigation. >> attorney general barr appears to have shown an unsettling willingness to undermine his own department in order to protect president trump. barr's words and actions suggest he has been disingenuous and misleading in saying the president is clear of wrongdoing. >> reporter: president trump took off for a long easter weekend in florida without taking questions about the redacted mueller report. earlier, he discredited the investigation and once again used his catchphrase, "no collusion."

>> there never was, by the way, and there never will be, and we do have to get to the bottom of these things, i will say. this should never happen. >> reporter: on twitter, he channeled the tv show "game of thrones," proclaiming "game over." but despite repeated declarations of exoneration from the white house. >> i call this a political proctology exam. actually the attorney general and the deputy attorney general in the original four-page memo said they found no basis for the obstruction in the four-page memo, and you know he has been cleared. >> we're very, very happy. it's a clear victory. any lawyer would say when you get a declaration, you just won. >> reporter: president trump, his associates and the trump campaign could face other legal challenges. the special counsel referred a total of 14 matters of potential criminal activity to other prosecutors, like the case involving michael cohen, the president's former fixer and personal attorney. he pleaded guilty to several charges, including campaign finance violations linked to hush money payments to women who

claimed to have had affairth new york state is also investigating the president's business dealings and financial holdings. after leaving the white house today, president trump tweeted he could have ended the whole witch hunt and fired everyone, including mueller, if he wanted to. he also pointed out his decision not to use executive privilege to withhold parts of the report. jeff? >> the "cbs overnight news" will be right back.

this is the "cbs overnight news." >> tomorrow is the 20th anniversary of a senseless act of violence, the columbine school massacre. a dozen students and a teacher were killed by two young gunmen. since then, the people who live in littleton, colorado, have taken steps to make sure something like that never happens again. barry petersen reports. >> reporter: we were the first network news team allowed inside this very sophisticated simulator. it's used to train first responder, including those who work in the school district that includes combe, at frighteningly real. fair warning, these images may be disturbing to some people.

>> i have people scream. >> reporter: in a simulator, school protective officer michael ortega took me into a hell we increasingly face, a school shooting. >> i've got a corner here, i've got a corner here! >> reporter: adrenaline pumping, he faces life or death. >> suspect down, suspect down, shots fired, shots fired, i need backup now! second suspect. >> reporter: the moment you get the call, that's the moment you start planning what you're going to do? >> yes. yes. in a situation like this where it's an active shooter, i could be going in alone. that's the whole purpose of an active shooter situation is get there and stop the threat. >> reporter: that's how much tactics have changed because of columbine. in that era, police waited for a s.w.a.t. team. and in those minutes, the shooters killed killing. now in colorado, officers are told go in alone. get the shooter. >> good speed in the hallways of this former elementary school, under the watchful eye of arvada

police lieutenant. >> can i make a difference? can i save lives? and finally, is it worth it? you have to put yourselves in the mind-set that you're going to go forward and save innocent lives. >> reporter: this classroom with the eerie cutouts of kids, some with guns is part of that training overseen by john mcdonald. >> we're trying to train to respond to any threat. and in today -- >> reporter: any threat being a child? >> any threat at any age. >> reporter: he is executive director for school safety in the district that includes columbine. >> what have we got today? >> reporter: today there are cameras everywhere, monitored 24/7, doors that can be locked remotely, armed officers inside the schools. >> we can pick up a suspect on camera. they can send me a picture, and so as we arrive, we don't have to try and figure out who the bad guy is or a booed guy is. >> reporter: on that day police were hampered because they had no idea of the school layout. >> maps and blueprints. >> reporter: now mcdonald carries a blueprint of every

school in his district. there is a state website called safe 2 tell for anonymous tips, and social media is monitored for any suspicious posts. >> if you say you're going to kill us, i believe you. if you say you're going to blow us up, we believe you. we're going to do everything in our power to make sure that that doesn't happen. >> reporter: what does it feel like when you're here? what do you think about? >> i think about all the students who were just like me who had their lives taken away from them. >> reporter: at the memorial dedicated to those who were killed, we talked with columbine seniors rachel hill and teagues simons, born after the shooting, they grew up in a time when active shooter drills start in kindergarten. do you feel safer being in this school because you know about that, or does it just make you scared because you've got to go through all these drills? >> reporter: i feel extraordinarily safe at columbine. the drills aren't overkill. >> i think it's made it easier to really focus on school because i'm not worried about being the victim of something. >> reporter: both favor second

amendment rights. teagues favors arming teachers. >> i don't think that every teach shore be allowed to have guns, but i definitely do believe that that could be an option. >> reporter: but rachel believes it could put teachers at risk. >> and so i think if someone goes in a school and they see a person with a gun, they don't know if they're good or bad. they don't know if they've killed others. they're going to shoot. >> reporter: no one imagined the mass murder of a school shooting could happen here. now with precautions and training, columbine may be one of the safest schools in america. we talked to a teacher who was here 20 years ago when the shooting broke out. he ran down the hallway yelling at students to evacuate, and mostly they just gave him blank stares. now the students who go to this school are trained not just to respond but to respond instantly.

there is a scandal brewing in the world of online dog sitting services. two popular app, wag and rover are being accused of hiring dog walkers and sitters who have actually mistreated some pets. chip reid has that. >> he was the one dog meant for me. >> reporter: colleen nolan says she built her life around her 12-year-old japanese chin named mushu. adopted at eight weeks old. when a work tri last s worried about e was

blind. >> i wanted to make sure he was comfortable in his surroundings, that he stayed in the home. so i reached out to rover to try to find a sitter. >> reporter: rover and wag are popular apps that connect owners and walkers with sitters. they promise rigorous screening and background checks. nolan says she chose a rover sitter who had badge foss for working with seniors. she gave specific instructions. muxu was to be taken out of the house only for short walks. those instructions were ignored. >> reporter: you got an emergency text from the dog sitter. >> yeah. >> reporter: and what did it say. >> i called her and she said mux fell off my porch. >> reporter: fell off your porch? >> i said what do you mean your porch? >> reporter: because she was supposed to stay right here. >> how far did he fall?

and -- she said two stories. >> reporter: two stories. that's not a porch. >> not a porch. >> reporter: nolan says rover offered to cover half of the expenses following muxu's death following vet bill, cremation and the cost of a new dog, totalling $2,600, but with one condition, sign a strict confidentiality agreement. >> never tell my story, to never warn any other parent. >> reporter: so what did you do? >> i never called them back. >> reporter: rover advertises that fewer than 20% of sitters who apply are accepted. they say all must pass a background check and be approved by a team of specialists. what was your understanding of rover and their selectivity? >> i thought that with rover saying that they only select at review each one of these sitters, that clearly those badges had to mean that they vetted that. >> reporter: nolan's is not the only case. cbs news spoke to 14 families

who say their dogs died while in the care of rover or wag sitters. 12 of those incidents involved rover sitters. one user said she discovered her rover sitter had a criminal record, and users of both apps also told us they were asked to sign nondisclosure agreements following those incidents. in december, a wag walker was caught on surveillance video kicking and intimidating a dog. wag is currently being investigated by the better business bureau over claims made in their advertisements, including that walkers are vetted through a rigorous screening process. in a statement to cbs news, wag told us that in addition to background checks, they collect real-time information through the app to regularly assess walkers. rover told us sitters must also provide photos, testimonials, and pass a safety quiz. >> just pasting a badge on the website is not going to work yme.they'rintotoack that up with some kind of training. >> reporter: pet care industry experts such as carmen r

roostenbeck says the industry is beginning to adopt more retions, but for now pet owners should be looking for pet providers with professional licenses. >> if you had a child would you just accept a person on an app to take care of your child, or would you do more investigation? and that's when i encourage all pet owners to do. >> rover and wag told us that incidents like nolan's are rare, but they declined to provide exact numbers. but this a document obtained by cbs news from a lawsuit in california, rover says they don't keep track on their platform of how many dogs have died, and they told us the well-being of pets is their top priority, and they are continually working to improve safety. wag told us that they are committed to constantly improving their service and cared deeply about the safety of dogs. some of the biggest stars at the san diego zoo are taking their final bows. the last giant pandas are headed back to china. jamie yuccas reports.

>> reporter: from kicking back while munching on bamboo, to watching their roly-poly bodies tumbling on the ground, giant pandas are an iconic attraction at the san diego zoo. but now visitors are lining up for a last look at the adorable black and white bears. >> the black around the eyes, the white faces. the more you look at them and they look back at you, you're you know something that i don't know. that's what atracks us to them. >> reporter: zookeepers dallas dumont and kathy hawk have cared for the pandas for years. >> good girl! >> reporter: it was 1996 when bai yun arrived from china. at the time, pandas were endangered, so chinese authorities asked the zoo to help save the species from extinction. but when the breeding program began, bai yun and her proposed mate didn't have a magic moment. >> bai yun was very much interested in him, but he had nothing to do with her. she flirted with him. >> i know how she feels.

>> she would roll in the dirt and rub her face in the dirt, thinking she looked very pretty, and she would go trotting up to him and he would go whoa and run from her. >> reporter: so barbara durant, the zoo's director of reproductive sciences employed artificial insemination. it was successful, and research to decipher the mysteries of panda mating habits began. however, the length of a pregnancy remains a guessing game. >> we've had pregnancies reported as short as 85 days and as long as 185 days. the physiology is still a little bit mysterious. >> reporter: luckily, bai yun's second suitor gau gau won her over. pandas are born blind and deaf. as cubs learn to climb, it's not unusual for them to take a spill, something keepers discovered only when it first went down. >> we literally heard a collective gasp from the whole group in the panda exhibit, and everyone was beside themselve he shakes himse around, oh, i hope nobody saw that and back up the tree.

>> reporter: this was their sixth cub. cbs this morning was the first to meet the adorable ball of fluff in 2013. whether born here or abroad, all pandas belong to china. the zoo says successful breeding and an increase in successful conservation helped boost pandas to around 2,000, downgrading the panda from endangered to vulnerable in 2016. building bonds of trust with the pandas has allowed zookeepers to perform some medical tests without anesthesia. it's also helping them crate train the pandas for their journey back to panda. their new home will be the chinese conservation and research center where other san diego pandas now live. at 27, bai yun's breeding days are over, but that doesn't make it any easier for those who love her to say goodbye. is it almost like this is your child and they're leaving for college? >> absolutely. particularly withen with every
