whirlwind of action on capitol hill this wednesday morning. you could say it s a congressional hearing palooza on a slate of urgent topics from the origin of covid, the safety of air travel, the u.s. evacuation of afghanistan, and threats from around the world. that last topic is the focus of a hearing set to begin any second with the senate intelligence committee. we ll hear testimony from the nation s top intel chiefs including dni avril haines, cia director bill burns and fbi director chris wray. we can expect them to dive into a number of topics including new threats from china, questions about mishandling classified documents and concerns over domestic extremism. our team is monitoring this closely. meanwhile, in a different senate hearing, acting administrator of the faa is just moments away from testifying after weeks of disturbing headlines from the not so friendly skies, including a united passenger recently caught on camera attacking a flight attendant and threate
today. happening right now, the ntsb investigators are on the scene in ohio at oaf norfolk southern train wrecked in the state. the ntsb says no hazardous materials were released in that wreck after 28 train cars derailed in springfield on saturday. it prompted shelter in place orders for residents. it comes a month after the norfolk southern state crash in east palestine, ohio. crews are still working to remove that contaminated soil and liquid from the site. jason carroll is? springfield now. jason, what are you learning now about this latest crash in. reporter: the ntsb is planning to hold a briefing about two hours from now, abby, at 3:00. hopefully at that point we ll get more guidance, perhaps, in terms of exactly what happened here. we can tell you in terms of the latest derailment, it occurred on saturday about 3:00. there was a man there who caught it on his cell phone just as the training were tipping off. 28 trains out of 200 cards derailed, but again we are bein
night? next four years behind closed doors, president biden is huddling with advisers at camp trump were that s according to some of the sources we re talking to for his part, trump s debate prep appears to include posting on his truth, social official account. consider this rant that says, quote, drug test for crooked joe biden. i would also immediately agreed one that s from the former president and club. it s the latest bizarre and baseless suggestion for trump and his allies that biden will need some sort of performance enhancing drugs for the cnn showdown, recovering both campaigns this morning with cnn s kristen holmes and kevin lip tack. kevin, let s begin with you. there s a new ad from the biden campaign. what s it say? yeah, i think it does give you a preview of the economic message that they re going to focus on the debate because as you mentioned and as is typical, the president and his team are getting a lot of incoming from democrats. they re concerned about t
action to correct this. i have some minor issues with it. they re going to have more detectors put in and in particular acoustic bearing detectors that have the ability to detect deterioraing bearings long before they start overheating and seizing. they have some on norfolk southern already, but not in this territory that they acquired from con rail to the best of my knowledge. basically i would congratulate him on that. i would also suggest to mr. shaw that norfolk southern tie in their detectors with their ptc digital data communications network so that the information
it has to do mainly with the hot bearings, which is part of the reason we saw what happened in east palestine. there was a wheel bearing that had overheated. the crew was not alerted in time, so what has happened is norfolk southern has comes up with a six-point plan that includes updating the detector s ability to catch overheated bearings, to do that more effectively. another point is review the standards and practices for using hot bearing detectors. three, abby, they ll be adding 13 new acoustic detectors, which apparently are able to spot a problem that a visual inspection cannot. so some of the things that they are adding here to try to improve their system, but i have to tell you very quickly, one of the things the critics say, one simple thing you can do is add more crews to some of these
