getting aircraft and crews repositioned to take care of our customers. the airline blaming weather and air traffic control for the mass cancellations. but the faa saying there have been no major air

management's poor planning, as well as any external operational challenges. >> we feel for those passengers. phil, what is southwest's message to the thousands of passengers left stranded tonight? >> reporter: right now, southwest says it's harder to recover from a disruption like this because it's operating fewer flights since the pandemic. the airline is offering a bit more flexibility to passengers when they go to the website to self-rebook. but other than that, it's just an apology and asking passengers for patience. >> phil, thank you. now to the extreme weather alert in the southern plains, where 14 million people from texas to missouri are facing a significant tornado threat. let's get right to rob marciano with the latest. hey, rob. >> reporter: hi, linsey. this is the

are threatening criminal penalties for those who refuse to comply with subpoenas. abc news has exclusive new information about what sources say was going on inside the trump white house as insurrectionists were storming the capitol. here's jonathan karl. >> reporter: what was donald trump doing at the white house the cion by president biden to turn over confidential white house documents to the house committee investigating january 6th may shed light into what trump, his aides, and members of his family were up to. one thing certain to be of interest to the committee is related to the controversial video trump released more than two hours after the capitol was breached. trump told his supporters to go home, but he also praised them. >> we love you. you are very special. >> reporter: in reporting for my upcoming book, "betrayal: the final act of the trump show," sources told me that trump recorded multiple takes of that video that were deemed unacceptable by his aides because he praised the rioters. but he didn't tell them to go home. those outtakes, i'm told, were videotaped by white house photographers, and are government property, and would provide insight into trump's state of mind on that day. trump has vowed to fight to keep such documents secret, citing executive privilege. biden disagrees. >> he believes it to be of the utmost importance for both congress and the american people to have a complete understanding of the events of that day to prevent them from happening again. >> reporter: in reporting for "betrayal," i spoke to several people who were in contact with trump during the riot. trump, the sources say, was watching tv in his private dining room. he liked what he saw. he boasted about the size of the crowd, and he argued with aides who wanted him to call on his supporters to stop rioting. the book reveals more details about kevin mccarthy's call to trump as the rioters stormed the house chamber. according to a source familiar with the call, mccarthy, frustrated at trump's indifference to what was happening, said, "i just got evacuated from the capitol. there were shots fired right off the house floor. you need to make this stop." the source said trump pushed back, saying, "they are just more upset than you because they believe it more than you, kevin." referring to the lie that the election had been stolen. >> just remarkable reporting there, jon. another one of trump's allies, steve bannon, is also claiming executive privilege. so is he defying a congressional subpoena? >> reporter: he sure is. and bannon's attorney has made it clear bannon is defying the committee at the direction of former president trump, who doesn't want any of his former aides to cooperate, citing executive privilege. even though bannon would be asked about things that happened long after he left the white house. he almost certainly will face a contempt of congress citation, and it could result in up to a year in jail. >> jon, thank you. tonight, the release of body camera footage raising some concerns. the man, a paraplegic, pulled from his car by officers. here's elwyn lopez. >> reporter: tonight, police body camera video showing the moment officers yank clifford owensby out of a car by his hair and arm after he tells police he's a paraplegic. >> someone help! >> reporter: the police stopping the 39-year-old late last month in dayton, ohio, saying they saw him leave a suspected drug house. one officer heard several times offering assistance. >> i can't get out of the vehicle, sir. >> sir, i'm going to assist you out of the vehicle. >> no, you're not. no, you're not. no, you're not. you're not going to touch me. >> reporter: owensby then pulled from the car and pinned against the ground. >> please help me! >> stop! stop! >> reporter: police say $22,000 in cash was found in the car. a narcotics k-9 alerting to it, meaning, they say, it had been in close proximity to illegal drugs. tonight, it will be in the hands of the city prosecutor as to whether owensby will face any charges. the dayton fraternal order of police saying the officers followed the law. adding, "sometimes the arrest of noncompliant individuals is not pretty." tonight, owensby says he's considering filing a complaint against the department. >> elwyn, thank you. next to texas, where the legal back and forth over the highly restrictive abortion law is just getting going. an appeals court has reinstated the law, coming nearly 48 hours after a judge had halted it. this means women in texas who want an abortion after six weeks now have to travel out of state. here's maryalice parks. >> reporter: tonight, with the nation's most restrictive abortion ban back in effect for now, health care providers again forced to turn away patients. >> there's a lot of anguish, a lot of pain. desperation. >> reporter: the 5th circuit federal court of appeals temporarily reinstating the ban just two days after a lowr court had paused the law. >> we've had patients who thought they could maybe get into a clinic in the state. and now after the ruling, we'll have to figure out how to travel again. >> reporter: on wednesday after the law was halted, some providers say they did open their doors for abortion services. but now they could be in legal jeopardy for doing so. anti-abortion advocates calling the latest court order a victory. >> we're out here to help the women make a better choice for their lives. >> reporter: not only does the law ban abortions after around six weeks, before most women even know they are pregnant, but it also allows average citizens to bring a lawsuit against someone they think helped facilitate the abortion. that fact has made it harder for the biden administration to challenge the law in court. >> who do you sue when the law empowers every citizen in the united states to be able to bring this lawsuit? >> reporter: the department of justice now has until tuesday to make their next legal move. it's likely the supreme court will eventually weigh in on the merits of that texas law. and in december, the new conservative majority on the bench here will face its first major test on abortion, with another case from mississippi that directly asks the justice to consider overturning roe v. wade. linsey? >> maryalice, thank you. a navy nuclear engineer and his wife are under arrest tonight. the fbi says they were allegedly trying to pass america's nuclear sub secrets to another country. investigators say the engineer was communicating with an undercover fbi agent, allegedly making three drops of information. including one where he allegedly put an sd card inside a peanut butter sandwich. new details in the remarkable story of survival, and the joyful reunion with the family of a 3-year-old, the texas boy who had been missing for found days found saturday. he was thirsty, but remarkably in good health. here's marcus moore. >> reporter: this image says it all. relief for this texas mother holding her son again, four anguishing days after he vanished into the woods near their home. >> the child was found alive. he is alive, he's thirsty, he is with his mother and is going to the hospital. >> praise the lord. >> yes, sir. yes, sir. >> reporter: a landowner who'd heard about 3-year-old christopher ramirez's disappearance during bible study went searching for the boy on his own, authorities say finding him in a thick wooded area, five miles away from his home. >> a citizen was walking his property and heard a whimper, maybe a cry, and saw a little boy. took him -- took him in his arms and called in. >> reporter: they said christopher was calm, but dehydrated. and tonight he's safe. the toddler disappeared wednesday after chasing a family dog into the woods as his family returned from the grocery store. his mother pleading for help in finding her little boy. local authorities, volunteers, and even the fbi joining the urgent search. but for days there was no sign of christopher until saturday's miraculous discovery. >> he ought to be the ultimate army ranger, navy s.e.a.l., air force, para rescue when he wants to grow up. he's already passed the first test. >> reporter: right now, christopher is at a houston area hospital under observation. but he's said to be okay. >> marcus, thank you. and there's still much more ahead on
