experienced today." the comatose 22-year-old college student was flown back to the u.s. last tuesday. two days later, fred warmbier described greeting his son for the first time in two years. >> i knelt down by his side, and i hugged him. and i told him i missed him and i was so glad that he made it home. >> reporter: north korean officials claim otto fell into a orma after he contracted botulism and took a sleeping pill shortly after he was sentenced to 15 years of hard labor. he was convicted for committing a hostile act after allegedly afealing a propaganda poster during a tourist trip last year. last week, doctors at the university of cincinnati medical center said he showed no sign of a botulism infection. anad physician daniel kanter tys the brain injury was likely caused by a sudden stopping of the heart. >> there's severe injury to all theons of the brain. >> reporter: wearing the same jacket that his son wore during

the car burst into flames. security forces in the convoy moved in quickly to put out the fire and pull the attacker out. he died at the scene. ine interior ministry says the attempted attack was deliberate. tside the trunk of the car were explosives and weapons. the 31-year-old man was reportedly from the paris suburbs and known to french intelligence. this is not the first time. earlier this month, a man attacked a police patrol with a hammer at notre dame cathedral, and in april, a police officer was shot and killed on the champs-elysées. as france remains on high alert, e unter-terrorism police have been put in charge of this investigation. >> reporter: i'm elizabeth palmer in london, where police say today's attack was not only terrorism, it was also a hate crime. the driver of the truck, who witnesses say shouted, "i want to kill muslims," barreled into

a small group of people near a north london mosque. ene attacker, identified as 47- year-old darren osborne, was pinned to the ground, shielded by some bystanders while others pushed to get their hands on him. >> why did you do that? >> reporter: the local imam made sure he was handed over to the police. mohammed mahmoud: >> we told them the situation, that there's a man, he's restrained. he mowed down a group of people ofth his van, and there is a mob attempting to hurt him. >> reporter: just over two weeks ago, londoners were paying their respects to victims of the last attack with a rented van on the rindon bridge by self-proclaimed islamic extremists. even then, security forces were dreading the kind of tit for tat terrorist violence that could rip holes in london's multicultural fabric. today, britain's prime minister, theresa may, appeared with religious leaders of all faiths

fo appeal one more time for solidarity. >> there is no place for this hatred in our country today, and we need to work together as one society, as one community to drive out this evil that is affecting so many families. >> reporter: british media are reporting that the attacker, darren osborne, was a father of four who lived in wales. security services says he wasn't on their radar at all, but tonight, his family is saying that he had been what they call "troubled" for some time. anthony? >> mason: elizabeth palmer in london. thanks, liz. turning now to the threat in the skies, homeland security correspondent jeff pegues has new information about what caused the u.s. to ban laptops from some overseas flights. >> reporter: u.s. officials are growing increasingly concerned about the terrorist organizations' capabilities to rnrget planes. one source tells us the threat is evolving rapidly and more

terrorists are gaining the knowledge necessary to build a laptop bomb. earlier this month, secretary of homeland security john kelly hnid there has been an unprecedented spike in terrorist travel. >> there are more terrorist hot spots and foot soldiers now than almost any time in modern history. >> reporter: in march, cbs news confirmed the terrorist groups have been testing a bomb that can be hidden in a laptop computer to evade security eeanners. n me of the intelligence was gathered at mosul university in iraq. the u.s. uncovered evidence that isis was testing the explosive on screening equipment taken from the city's international airport in 2014. that led the trump administration to ban larger electronics in the cabins of airplanes traveling to the u.s. from some airports in africa and the middle east. secretary kelly is weighing whether to expand that ban to include europe. john pistole is the former head of the t.s.a. >> there are significant logistical challenges in implementing a ban of this

magnitude from such popular airports such as heathrow or urankfurt or amsterdam or charles de gaulle. s reporter: sources say some airports have already put enhanced security measures in place. anthony, as u.s. and coalition forces continue to take back isis-controlled territory in iraq and syria, more isis- trained fighters are expected to migrate to countries where air travel to the u.s. is easier. >> mason: jeff pegues, thanks, jeff. now to a question without a clear answer. a question julianna goldman put to the president today. >> reporter: mr. president, are you under investigation by the l?ecial counsel? tresident trump ignored shouted questions today about whether he is a target of the federal investigation into russian interference in the 2016 election, and he declined to clear up the discrepancy between his tweet from last week, saying hi was being investigated, and comments from one of his attorneys, jay sekulow, over the weekend. >> i want to be clear here: the president is not under investigation.

so the president is not under investigation, has not been. we have not been notified there is an investigation of the president of the united states. >> reporter: notifying targets of up to the discretion of special counsel robert mueller, and such notifications tend not to go out until later stages of icderal investigations. >> it's great to have you at the white house. >> reporter: publicly the white house is operating as business as usual and appears to be sulstering mr. trump's son-in- law and senior adviser jared kushner, even as f.b.i. scrutiny of his russia connections intensifies. >> before i came to washington, many warned me that the bureaucracy would resist any change that we tried to implement. so far i have found exactly the opposite. >> reporter: kushner made a rare toblic speech today to business lod technology leaders, and this week he's traveling to the middle east for peace talks, but we's also looking to hire a new attorney, his current lawyer, m mie gorelick, was a partner at the same law firm as special counsel mueller, presenting a potential conflict.

press secretary sean spicer briefed reporters but would not allow any recordings. he said on thee day the president is in front of cameras, mr. trump's voice should be heard. but anthony, that didn't include answering questions about the russia investigation. >> mason: julianna goldman at the white house. thanks, julianna. survivors of the collision of the u.s.s. "fitzgerald" and a cargo ship. seven members were killed in the saturday morning disaster. the investigation is just beginning. david martin is at the pentagon. >> reporter: how a top-of-the- >>ne u.s. navy war ship could be t-boned by a less maneuverable containership remains inexplicable, but the result is indisputable: seven american sailors dead and the u.s.s. uritzgerald" limping into court. vice admiral, joseph aucoin, commander of the seven fleet, said the crew had to fight to keep the ship afloat.

>> the damage is under the water line mostly, and it's a large .ash near the keel of the ship. >> reporter: japanese coast guard said the "a.c.x. crystal" plowed into the "fitzgerald" at 1:30 in the morning local time to the philippine-flagged vessel was headed from nagoya to offload cargo in tokyo bay. a web site that tracks commercial vessels shows the "crystal" making a sharp change of course at exactly that time, as if it had run into something and was coming about to see what it was. the container ship had a crew of only 20, and may well have been operating on autopilot. the fitzgerald and its crew of 300 was outbound. its bridge watch would have included an officer of the deck, radar operators and lookouts. they should have been able to see the "crystal" coming from at least ten miles away. that would leave plenty of time to alter course and to alert the captain. but commander bryce benson was

still in his cabin when the "crystal" struck. >> his cabin was destroyed. he's lucky to be alive. >> reporter: an investigation will determine who made what mistakes, but in the u.s. navy, the captain is held responsible for everything that happens aboard his ship. anthony? >> mason: david martin, thanks, david. bnsions between the u.s. and russia are rising after the u.s. downed a syrian jet yesterday. washington and moscow are backing different sides in syria's civil war, which has dragged on now for more than six years. holly williams has more on this. holly? >> reporter: anthony, the u.s. coalition says a syrian regime su22 fighter jet dropped bombs close to u.s.-backed forces on the ground southwest of raqqa. now, those forces are fighting against isis. they're supported by u.s. troops, and the bombs were so close that the u.s. sent an f-18 to shoot down the syrian jet, the first time that's happened during the syrian civil war.

now, russia, which backs the syrian regime, has retaliated by saying that it will now track all u.s. coalition aircraft as targets. russia also says that it is shutting down cooperation to prevent midair collisions, though general dunford, the chairman of the joint chiefs of staff, said today the two countries are still communicating and he warned against hyperbole. as isis loses ground in syria, pro-regime forces and u.s.- backed forces are bumping up against each other, increasing the danger of a miscalculation with the worst-case scenario being the u.s. and russia drawn into a direct conflict. >> mason: holly williams in istanbul, thanks. the supreme court ruled today in two free speech cases. the justices said a ban on emfensive trademarks is unconstitutional. that's a victory for the asian american rock band the slants, battling to trademark their name. it also gives a boost to the washington redskins in their

fight to keep the trademark to their name. in the other case, the court struck down a north carolina law that banned sex offenders from social media web sites.
