Former president playing cleanup after posting a nazi phrase on his website and suggesting restrictions on contraceptions in an interview. Rachel scott has the story. Good morning, rachel. Reporter george, good morning. Former President Trump was asked directly whether he would support restrictions on Birth Control. The former president said it was something they were looking at, only to back track hours later. This morning donald trump walking back his comments suggesting hes open to restricting Birth Control if reelected. Do you support any restrictions on a persons right to contraception . Well, were looking at that. Im going to have is a policy on that very shortly. I think its something youll find interesting. Its another issue thats very interesting. But you will find it, i think, very smart. I think its a smart decision. But we will be releasing it very soon. Reporter in an interview with a local pittsburgh tv station the former president asked to clarify if that meant he would, in fact, support restrictions on contraception. You may want to support some restrictions . Like the morning after pill or something . We are also you know, things really do have a lot to do with the states. Some states are going to have different policies than others. Reporter the Biden Campaign seizing on those words saying women across the country are already suffering from Donald Trumps post roe nightmare. If he wins a second term, its clear he wants to go even further. Hours later trump back tracked writing on social media he has never and will never advocate imposing restrictions on Birth Control or other contraceptives. Thats something he never made clear in the interview. The former president often boasts about appointing three of the five Supreme Court justices that overturned roe verse wade, clearing the way for 21 states to ban or restrict access to abortion. We broke roe v. Wade. Reporter just weeks ago trump told Time Magazine he wouldnt intervene if states wanted to monitor or punish pregnant women seeking abortion saying its irrelevant whether im comfortable or not. Because the states are going to make those decisions.

Now were going to turn to new details on the deadly turbulence aboard a Singapore Airlines flight. Ntsb is joining the investigation into the incident that killed one passenger and injured dozens more. Transportation correspondent gio benitez joins us with more. Good morning, gio. Gio michael, good morning. Truly tragic incident. Were talking about something called clear air turbulence. Thats what it appears to be. Thats when the weather is nice and smooth, people feel safe to stand up. They take off their seat belts. But then instantly, with little notice, weve got mayhem. This morning the ntsb heading to Southeast Asia to investigate that deadly turbulence incident on a flight from london to singapore that killed one passenger and sent at least 104 others to medical centers. The images are dramatic. Passengers being taken off on stretchers treated on the tarmac. Inside the plane, oxygen masks dangling, dented overhead bins, blood on the back of a seat. Passengers seen with cuts and bruises, bottles and food all over the floor. It was really, really quick, which is why i think nobody could really respond to it. The plane started shaking. It kept getting worse and worse and worse. I saw people from across the aisle just like going completely horizontal hitting the ceiling and landing back down in really awkward positions. People getting massive gashes in their head, concussions. Reporter Andrew Davies also on board. Very surreal. There was a lady screaming. Reporter among the 211 passengers and 18 crew members, four americans. The ceo for Singapore Airlines speaking out overnight, saying theyre cooperating with the investigation. We are very sorry for the traumatic experience that everyone on board the plane went through. Reporter heres what we know. The plane was flying from london to singapore but hit an air pocket. While it appears the sky may have been clear the sudden turbulence made the plane drop 100 feet then climb 300 feet. The people inside experiencing rapid negatives and positive gforce. If they didnt have a seat belt on, they would have hit the ceiling then slammed into the floor. The plane making an Emergency Landing in bangkok. As of now most commercial airplanes have no way to detect this kind of clear earth turbulence. We believe the weather was fairly good. We believe that the airplane had its weather radar on. The seat belt sign, apparently, only came on a few seconds prior to hitting this turbulence. Reporter two of the injured, americans. At least six passengers injured so badly that they are in Critical Condition this morning. The passenger who lost his life, 73yearold British National jeff kitchen a bangkok airport manager said they believe he may have suffered a heart attack but that has not been confirmed. And we, of course, are thinking of his family. Again, the american ntsb will now join in on this investigation. But now so many people have incidents like these on their minds because there are so many people traveling right now. Robin as americans gear up for the big Holiday Travel weekend, gio, how are some of the busiest airports in the country, like where you are in chicago, how are they preparing . Gio thats right, robin. United brought us on to the tarmac. This plane is going to orlando. Thats one of the Top Destinations for memorial day. Were talking about 4,400 flights a day just from united. Thats three flights taking off very single minute. Tomorrow will be the busiest before the holiday. 53,000 flights. Then friday, 50,000 flights. Make sure you come here early. Make sure you get the airlines app on your phone so that you can make any quick changes that you need to make there. Michael . Michael gio, thank you. In other words, give yourself a lot of time. We always appreciate you there standing on the tarmac. Holiday road trips are expected to reach record levels as well. Janai norman is tracking what to expect. Good morning, janai. Reporter michael, good morning. Gio just mentioned orlando. Hertz said thats one of the cities with the highest demand for rental cars because so many people will be hitting the road. So buckle up. This is expected to be one of the busiest memorial day rushes ever on the road according to aaa. An estimated, staggering 38. 5 Million People are expected to travel by car. The highest ever since tracking began back in 2000. Thats up about 2 from 2019, up 4 from last year. That means traffic and congestion in many areas. Planning ahead can help. The folks who analyze traffic data, they say if you leave thursday or friday, you gotta get going early to avoid that morning rush, or wait until the evening. When youre returning home on sunday or monday, they say that youll want to time your travel to avoid the evening commute. The worst time to be on the road, according to aaa, will be from 3 00 p. M. To 7 00 p. M. Those days. They say drive times could take up to 90 longer than usual. You want to make sure you have a full tank of gas. A regular gallon of gas will run you about 3. 61. Thats about a nickel more from where gas prices were last year. But, guys, its almost summer. Thats good news. Robin always that Silver Lining you bring us, janai. Thank you. All right.
