good evening. thank you for joining us. president trump is set to

officially launch his bid for re-election tomorrow. you no, abc news has an unprecedented look inside his world, embedding with him for 30 hours in the white house and on the campaign trail, showing a side of the president that few have seen before. >> mr. president. mr. president, could you -- >> reporter: it's a rare inside look at the 45th president. abc news had exclusive access over two days. a welcome surprise for reporters whom he's called the enemy of the people. >> hello, folks. how are you? hi, george. >> reporter: our chief anchor george stephanopoulos. there from the moment the president began his day. >> good morning, mr. president. how are you? >> reporter: to the very end. with some very candid moments in between. >> at some point i hope they get it because it's a phenomenal -- it's a fantastic financial statement. it's a fantastic financial statement. and -- let's do that over. he's coughing in the middle of my answer. >> yeah. okay. >> i don't like that.

you know? >> your chief of staff. >> if you're going to cough, please leave the room. >> i should get a shot of -- i'm going to come over here just to change the shot. >> you just can't -- >> sorry. >> okay. do you want to do that a little differently, then? >> yeah. we just changed the angle. yep. >> reporter: we first hit the campaign trail in iowa with the commander in chief as he prepares to officially launch his bid for a second term, hitching a ride in his brand new presidential limo, the beast. >> these people are so incredible. look, the crying and -- they're so cute. >> what's your pitch to the swing voter on the fence? >> safety, security, great economy. i think i've done more than any other first-term preside i have a phony witch hunt which is just a phony pile of stuff. mueller comes out, there's no collusion, and essentially a ruling that no obstruction. and they keep going with it. you know what? people are angry about it. >> i don't think that's what he found. but we don't have time for that now, we'll talk -- >> excuse me. he found no collusion. and he didn't find anything

having to do with obstruction because they made a ruling based on his findings and they said no obstruction. >> and he didn't examine collusion. he laid out evidence -- >> are you trying to say now that there was collusion even though he said there is no collusion? >> he didn't say there's no collusion. >> and he said no collusion. >> he said he didn't look at collusion. >> george, the report said no collusion. >> did you read the report? >> yes, i did. and you should read it too. >> i read every -- >> let's go. you should read it too, george. >> show us around. >> reporter: in the oval office the next day the president still defending himself. >> he didn't look at collusion. he said there was -- >> you should read the report. >> i did. he said there's insufficient evidence -- >> read the conclusion of the report. just read it. okay? sometimes i have false fights. like the russian witch hunt. that's a false fight. that's a made-up hoax. and i had -- >> the first line of his report says they had a systematic attempt to interfere in our elections. >> they did. but not me. and they also said, okay? that we rebuffed them. >> well, they said your campaign welcomed the help.

>> excuse me. the trump campaign rebuffed them. now, anything having to do with russia had nothing to do with our campaign. >> paul manafort. >> paul manafort, they have paul manafort on taxes and many other things. nothing -- >> giving polling information to the russians. >> i don't know anything about that. what difference does polling information make? it doesn't matter. and putin, i will say this, if he had it, it was up to him, he would much rather have hillary clinton be president right now and awful these countries would rather have biden or anybody else -- >> he said -- >> okay. let's put yourself in a position, you're a congressman. somebody comes up and says, hey, i have information on your opponent. do you call the fbi? >> if it's coming from russia you do. >> i've seen a lot of things over my life. i don't think in my whole life i've called the fbi. this is somebody who said we have information on your opponent. oh. let me call the fbi. give me a break. life doesn't work that way. >> fbi director says that's what should happen. >> the fbi director is wrong. >> your campaign this time around, if foreigners, if russia, if china, if someone

else offers you information on opponents, should they accept it or should they call the fbi? >> i think maybe you do both. i think you might want to listen. i don't -- there's nothing wrong with listening. if somebody called from a country, norway, we have information on your opponent. okay. i think i'd want to hear it. >> you want that kind of intd feern interference in our elections? >> it's not interference. it's information. i think i'd take it. if i thought there was something wrong i'd go maybe to the fbi. if i thought there was something wrong. >> reporter: those comments became the subject of swift backlash. two days later trump telling fox news he would still look at the dirt but -- >> of course you to look at it because if you don't look at it you're not going to know if it's bad. how are you going to know if it's bad? but of course you give it to the fbi or report it to the attorney general or somebody. >> reporter: yesterday in an interview with my colleague jonathan karl representative alexandria ocasio-cortez said that the time for an impeachment inquiry was now. >> well, i think every day that

passes the pressure to impeach grows. >> reporter: meanwhile, speaker nancy pelosi on cnn downplayed democrats' efforts to impeach. >> i don't think there's anything more divisive we can do than to impeach a president of the united states. >> reporter: while we were out on the trail with the president in iowa -- >> okay. >> reporter: -- former vice president joe biden was also on the ground and on the attack. >> i believe that the president is literally an existential threat to america. >> he's still leading the polls on the democratic side. it's tightening up a little bit. and -- >> it's tightening up a lot, which is interesting. >> but he's still beating you according to the polls. >> well, i don't believe theose polls. there's no way he beats me in text pex. >> >> but even your polls show you're behind right now. >> no, those polls show me i'm winning everywhere. >> reporter: those polls all kuming for the president that a few seconds later he went off record to call his campaign manager. >> just call brent -- >> reporter: days later nbc news obtained some of that internal trump polling data confirmed by

the campaign that showed the president far behind in key battleground states earlier this spring. but the campaign said that more recent polls show a vast improvement. >> good morning, mr. president. >> reporter: back in the white house the next day the polling still on the president's mind. >> "good morning america" today they had that phony polling information. i explained to you last night that it was phony but you didn't do anything about it. >> why does it bother you so much? >> because it's untrue. i like the truth. i'm actually a very honest guy. if i thought they were correct i wouldn't be complaining at all. i understand that. it's like the witch hunt that goes on. no collusion with russia. there was no collusion. >> reporter: by sunday the trump campaign had cut ties with a number of its pollsters. while overseas the president has taken an out of the box approach to foreign policy, striking an unusually warm relationship with north korean dictator kim jong un.

d telathip is very well, butciat the letter. >> one year ago today you with in singapore and you put out that tweet, there's no longer a nuclear threat from north korea. but there is a nuclear threat today, isn't there? >> well, it could change. i would say not much. there's been no nuclear testing except for very short range. and that's something that a lot of nations test, frankly, what he tested. i think we've made tremendous progress. >> you think he's still building nuclear weapons? >> i don't know. i hope not. he promised me he wouldn't be. he promised me he wouldn't be testing. >> so you still trust him? >> well, look, i couldn't tell you that. it would be very insulting to him. but the answer is yeah, i believe that he would like to do something. i believe he respects me. >> at some point could he be playing you too? >> well, look, i put on sanctions. the sanctions are on. hostages .

we've gotten the remains of our great heroes. >> reporter: george asked the president built return of one american, college student otto warmbier, who came back from north korea in a comatose state and later died. brazenly the north koreans reportedly billed the united states $2 million for warmbier's medical care. >> did they try to make you pay for otto warmbier? >> well, when you say me -- >> the united states. >> because i didn't know him at that time. that was a very different deal. but here's the bottom line. i ended it. we didn't pay. and i have great respect for otto's parents. and what happened to otto is horrible. horrible. but we never paid for otto. >> reporter: the uncertain relationship with north korea will likely follow him as the campaign cycle heats up. [ cheers ] >> thank you very much, iowa. we love iowa. thank you very much. >> reporter: president trump has his eye of course on the 2020 campaign. but he's also thinking about his

legacy. on his agenda, a redesigned air force one. >> so you know, the big news is we ordered a new plane. >> reporter: it's the first time since the kennedys who changed the color from orange to iconic blue and white. >> red, white and blue. >> you designed it? >> yeah. it was time. >> reporter: a striking resemblance to trump's personal plane, known as trump force one. our 30 hours with president trump ends here in the white house with the serenade by the marine band. ♪ he and the first lady ascend the stairs to their private quarters. a most traditional of rituals for a most untraditional president. ♪ you can watch the interviews with the president from that 30-hour time period on abcnews.com. next, o.j. simpson's first tweet 25 years after the police pursuit that gripped the nation.

o.j. simpson has joined twitter, going public after keeping a low profile since his release from prison two years ago. on his mind, the kardashians. here's abc's linsey davis. >> hey, twitter world. this is yours truly. coming soon to twitter, you'll get to read all my thoughts and opinions on just about everything. >> reporter: the juice is back on the loose. this time on twr.hi sd be lf fu to do. >> reporter: o.j. simpson joining the social media site, racking up nearly 700,000

followers and counting since his first post this weekend. >> you know, for years people have been able to say whatever they want to say about me with no accountability. but now i get to challenge a lot of that b.s. and set the record straight. >> reporter: for the last two years he's been living in this gated community in las vegas. but that quiet life may now be behind him. his top trending order of business, the kardashians. slapping down rumors that he was romantically involved with his lawyer rob kardashian's wife, kris jenner, and also denying that he's khloe's real father. >> all of these stories are just bogus. bad. you know, tasteless. khloe, like all the girls, i'm very proud of, just like i know bob would be if he was here bup the simple facts of the matter is she's not mine. >> reporter: for some simpson's twitter page is opening old wounds. >> i feel anxious again. and it's hard.

it's just -- you know, he's living a very large life. he's revered in las vegas. and now to see the response that he's getting on twitter, it's hard. >> reporter: kim goldman's brother, ron, was murdered alongside simpson's ex-wife, nicole brown simpson. o.j. simpson was put on trial for their murders but was acquitted in what was called the trial of the century. >> not guilty of the crime of murder. >> i tried to figure out a place to put it in my life so it doesn't suffocate me. so while other people can just turn oft television or turn the magazine over, it leaves a mark. >> reporter: the reaction online to his newfound twitter fame, scathing. chelsea handler writing, "let's all take a moment to be happy o.j. simpson joined witter and not trump's cabinet." bill eye eichner slamming his followers saying "seriously, what the bleep is wrong with you?" >> i've got a little getting evening to dop. >> interpreter: and john oliver probing the particulars of his

message. >> what does getting even mean in his message? when you kill two people you're even, three people you're odd, four people you're even? i don't know. >> reporter: simpson sending out his inaugural tweet 25 years after the infamous bronco chase that riveted the country. >> we've been outside o.j. simpson's house all day long. >> reporter: abc's jim avila was a local reporter in los angeles with a front row seat to those early moments. >> the city of los angeles at that time was standing still. i mean, everything stopped. >> the bronco chase captivated the nation. in fact, we might even say it was the beginning and maybe the launch even before it was called that, reality tv. >> reporter: all of it broadcast live. 95 million people watching. involving one of the biggest names of the time. >> he was bigger than life, bigger than race, bigger than sports because he combined awful those things. so now you have o.j. cast in a whole different role. now o.j. simpson, an accused murderer.

>> reporter: the chase marked the beginning of what became a media circus. simpson was put on trial for the murder of his ex-wife and her friend. millions watching every twist and turn of the court proceedings. >> if it doesn't fit, you must acquit. >> reporter: it became a national reckoning. >> free o.j.! >> reporter: exposing long simmering racial tensions and ongoing mistrust of the los angeles police department. in the end a jury acquitted simpson after only three hours of deliberation. >> we all got a lesson in how divided this country was. it wasn't a trial about o.j. simpson's guilt or innocence. it was a trial of the los angeles police department. >> reporter: kim goldman was there in court. and all these years later she's still grappling with what happened. >> i learned very quickly that the truth doesn't really need to show up in a courtroom. honor doesn't really have to take place in a courtroom. it didn't give us what we deserve. >> reporter: she created a podcast called "confront's o.j. simpson," coming face to face with some of the key players involved in the case, many who became household names.

less than two years after the criminal case o.j. simpson was found liable for the deaths of nicole and ron in a civil trial. >> the judgment for both families was $33.5 million. has he willingly paid anything? no. the only justice that would have mattered when it comes right down to it is that he would have been in jail on death row. >> reporter: but in 2007 surveillance video captured simpson stealing sports memorabilia from a hotel room in las vegas. the charges landed him in a courtroom again. this time simpson would end up in prison, convicted of robbery and kidnapping. but in 2017 he was released on parole after serving nine years. >> he's lived his life. he's had opportunities to do things. ron didn't. >> reporter: simpson told the associated press, "we don't need to go back and relive the worst day of our lives.

the subject of the moment is the subject i will never revisit again. my family and i have moved on to what we call the no negative zone. we focus on the positives." >> at the end of the day o.j. simpson represented controversy, conflict, division, and these were the things in fact in any season, any era, that's always going to draw a mass audience, mass attention. >> i'll be able to talk about everything. >> reporter: as for how much attention, we may be just one tweet away from knowing. for "nightline" i'm linsey davis in new york. >> our thanks to linsey. and up next, the record climb for one fearless 10-year-old. i'm mildly obsessed with numbers. so, i started with the stats regarding my moderate to severe plaque psoriasis. like how humira has been prescribed to over 300,000 patients. and how many patients saw clear or almost clear skin
