Jarrett william smith, stationed at ft. Riley, kansas, was arrested on saturday after allegedly talking to a confidential fbi source about placing a vehicle full of various explosive materials at a specific but unidentified news network. And smith allegedly said, 30 minutes later, boom. Cnn reporting tonight it is the targeted network. This case sets off so many alarms. The combination of an active duty soldier, trained, young and talking about harming other people. Its the absolute worst scenario for law enforcement. Reporter the fbi locked onto the 24yearold smith last march after receiving a tip that he was allegedly using facebook to distribute information about how to build improvised explosive devices. In a chilling exchange with an undercover agent, a democratic president ial candidates name is mentioned. The undercover asks, you got anyone down in texas that would be a good fit for fire, destruction and death . Smith allegedly responds, outside of beto, i dont know of enough people that would be relevant enough to cause a change if they died. He had all the right elements to commit a violent attack. So, lets get to pierre with us live tonight. Pierre, i know youve been reporting this out all afternoon. And your sources now telling you that some of these bomb designs were viable . Reporter yes, david. The fbi consulted a number of bomb experts and they said some designs were potentially dangerous. But Authorities Say a number of smiths alleged bomb designs would not have worked, including the one targeting that news headquarters. David . All right, Pierre Thomas leading us off tonight. Pierre, thank you. Next tonight, President Trump defiant. He was asked repeatedly today, did he put pressure on ukraine to investigate his potential 2020 challenger, joe biden . The president over the weekend admitting he did bring up joe biden on that call, and all of this as congress had already passed hundreds of millions in aid for ukraine, but that money had not been sent. But even with that money in the balance, the president tonight saying he was not putting pressure on the new president of ukraine. Heres abcs chief White House Correspondent jonathan karl, traveling with the president here in new york tonight. Reporter today, a defiant President Trump insisted he did nothing wrong by asking the president of ukraine to investigate his campaign rival, joe biden. We had a perfect phone call with the president of ukraine. Everybody knows it. Its just a democrat witch hunt. Here we go again. Reporter over the weekend, the president described the july 25th phone call with the newlyelected ukrainian president. The conversation i had was largely congratulatory, was largely corruption, all of the corruption taking place, was largely the fact that we dont want our people like Vice President biden and his son creating to the corruption already in the ukraine. Reporter in that conversation, the wall street journal reported that the president pushed eight times for an investigation into joe biden and his son, hunter, suggesting the ukrainian president work with his personal lawyer, rudy giuliani. At the time of the call, the Trump Administration was withholding 250 million in military aid to ukraine that congress had already approved. I did not make a statement that, you have to do this or im not going to give you a. I wouldnt do that. I wouldnt do that. Reporter but several minutes later, the president said it wouldnt have been wrong if he did do it. I put no pressure on them whatsoever. I could have. I think it would probably, possibly have been okay if i did, but i didnt. I didnt put any pressure on them whatsoever. Reporter and in another point today, the president seemed to acknowledge he did consider withholding aid unless the investigation into his political rival went forward. Were supporting a country, we want to make sure that country is honest. Its very important to talk about corruption. If you dont talk about corruption, why would you give money to a country that you think is corrupt . Reporter hunter biden did make tens of thousands of dollars a month working for a Ukrainian Company while his father was Vice President. But there has been no evidence of any wrongdoing. And biden is hitting back. Why is he on the phone with a foreign leader, trying to intimidate a foreign leader . If thats what happened . That appears what happened. You should be looking at trump. Jon karl with us here in new york tonight. Always good to have you here in person. You heard joe biden there over the weekend. He also tonight is now demanding that the white house release a transcript of this conversation. How likely is that . Reporter well, im told by multiple people close to the president that there is serious consideration in the white house of releasing the transcript. Will it happen, david, i frankly doubt it. Look, there are detailed word for word verbatim transcripts of most of the conversations the president has with a foreign leader. They almost never see the light of day. With the exception of when they are leaked, as happened twice in trumps first months in office, and at that point, they took steps to make sure it would never happen again. All right, so, well see. Jon, thank you. And of course, this phone call is under scrutiny because of that whistleblower who came forward, and tonight, House Speaker nancy pelosi already under growing pressure to move forward with impeachment, she is now issuing an ultimatum to the trump white house. Release the whistleblowers complaint by thursday or face, quote, a new level of investigation. What does that now mean . Heres mary bruce on the hill. Reporter if the Trump Administration doesnt hand over the whistleblower complaint by thursday, speaker of the house nancy pelosi is now hinting at impeachment, warning, they will be entering a grave new chapter of lawlessness which will take us into a whole new stage of investigation. Now, even democrats who have resisted calls to impeach say they may have little choice. He may force us to go down this road. And we may very well have crossed the rubicon here. Reporter the Inspector General determined the whistleblowers complaint was credible and of urgent concern. But on twitter today, the president questioned the whistleblowers patriotism, asking, is he on our countrys side . Where does he come from . For some democrats, impeachment is long overdue. Congresswoman alexandria ocasiocortez tweeting, the bigger National Scandal isnt the president s lawbreaking it is the democratic partys refusal to impeach him for it. While Republican Leaders . Largely silent. One exception senator mitt romney, tweeting, if the president asked or pressured ukraines president to investigate his political rival, it would be troubling in the thtion sulha o they well, that will be up to the house to decide how to proceed. So, lets get right to mary bruce. Shes with us live tonight, as well, from the hill. And mary, all eyes have been on Speaker Pelosi when it comes to impeachment. And youve reported here she has repeatedly called for restraint, saying follow the facts, but this sounded like an escalation from the speaker. Reporter well, david, the speaker has been walking this very fine line here for months, but now we are seeing a notable shift. And the speaker didnt even mention the word impeachment, but david, she didnt have to. It is clear shes suggesting this is now a possibility. David . Mary bruce live in washington. Thank you. We are also following tonight a tropical system set to hit puerto rico and the u. S. Virgin islands in the coming hours. Tonight, theyre now bracing for impact. And could the east coast be next . Lets get right to chief meteorologist ginger zee with the newest track tonight. We know youre watching a number of systems still out there. Reporter so many, i mean, from the dangerous flash flooding in arizona, because of their system, to, look at that atlantic basin, david. Tropical storm jerry, karen and lorenzo. Lorenzo does not look like it will be a threat to land but an immediate threat to land is tropical depression karen. Doesnt matter what its called, it will drop significant rain on puerto rico. Remember, puerto rico is not a flat island. Theyve got those mountains and you just need a couple of inches, but they could see four to eight inches, that would end up giving mudslides and, of course, debris floes possibility. The flash flooding could happen, st. Croix, st. Thomas. All watching for some of the impacts. But then, look at jerry. Tropical storm warning for bermuda. Very similar path to last weeks humberto. Luckily, this should stay in the Tropical Storm category. We hope it keeps that path out to sea. All right, ginger, thank you. And we turn next tonight to dramatic opening arguments in the trial of a former Dallas Police officer charged with murdering her neighbor. She claims she thought she was in her own apartment when she entered the wrong one on the wrong floor after work and killed who she thought was an intruder. It was his apartment. And tonight, the new evidence revealed. Abcs marcus moore from dallas. Reporter tonight, prosecutors saying botham jeans killing in his own apartment was completely avoidable. In front of bothams apartment is this extremely obvious bright red floor mat. Amber guyger had no floor mat. Reporter that dusty red mat is one of the many signs they say amber guyger, a former Dallas Police officer, missed the night she shot and killed the 26yearold. I thought i was in my apartment and i shot a guy thinking that he was thinking it was my apartment. Reporter prosecutors claim guyger, seen here on the phone after the shooting, had been sending intimate Text Messages and talking on the phone with her partner just moments before she walked into jeans home and was possibly distracted. They add, those messages were later deleted. Do you remember if they were provocative . I dont remember, no. Reporter guyger alleges she was exhausted after work and simply walked into the wrong apartment. Her attorneys say this was not murder but rather a tragic mistake. To say that she was aware there was a red door mat and knowingly ignored it because she wanted to go into 1478 and shoot this man is preposterous. Reporter and one of the Big Questions tonight is whether guyger will take the stand in her own defense. Her attorneys have said she will. And this trial is expected to last at least two weeks. David . Marcus moore reporting in tonight. Thank you. And next, to passengers at airports across this country and the world left stranded after the sudden collapse of the worlds oldest travel company.

What a mess tonight. James longman live from newark. Where some of those stranded hope to get on flights back home. The british government, we know, james, providing flights for its own citizens, but what about everyone else . Reporter yeah, thats the big question, david. We reached out to whats left of the company, but didnt get much of a straight answer. The u. S. Department for transportation says if u. S. Consumers need to, they can reach out to other airlines for help, but they do point out those companies are not obligated to provide assistance. David . James longman in newark tonight.
