good evening. it's great to have you with us on a very busy friday night. we begin with a deadly police shooting. the suspect shot and killed. tonight, there's video of the scene as it unfolded. one officer seen falling to the ground. they're trying to figure out if there was friendly fire. pierre thomas is on the scene tonight in washington. >> reporter: disturbing video shows police swarming over the suspect at the end of a dramatic foot chase. as shots ring out. it's not clear what triggered the gunfire or who shot first since the officers are in such close quarters, struggling with the suspect. but four shots can clearly be heard on the video. at least one apparently striking

this officer, who can be seen falling forward to the ground. both officers were wounded. the suspect later died of his wounds at a d.c. hospital. police say they recovered a handgun and are investigating whether the suspect fired his weapon and is responsible for wounding the officers. they're also investigating the possibility of friendly fire. >> we recovered a weapon from the suspect, and we believe that was fired. and we believe one of our officers discharged his weapon. >> reporter: so you don't know who shot first? >> that's what we're investigating. >> reporter: both officers will survive their wounds but the encounter shows the daily dangers officers increasingly face. in 2016, 64 officers were killed by gunfire, up 56% compared to the previous year. 21 of those officers were killed by ambush, a 163% spike over 2015. much of the violence against police now caught on tape.

is it your feeling that suspects are much more willing to combat police? >> it appears that way. >> pierre, the officers had body cams. will the recordings be released? >> reporter: police are reviewing the video and the mayor will decide whether to release it. david? >> pierre, thank you. tonight, we're learning more about the chemical agent used in the middle of a busy airport. authorities believe the world's deadliest toxin was used to kill kim jong-un's brother, the vx nerve agent.

it's colorless, odorless, and one woman became violently ill moments after. here's terry moran. >> reporter: the bizarre assassination at kuala lumpur's busy airport, now classified as a terrifying weapon of mass desctriction attack after malaysia's police chief revealed today the stunning toxicology results. >> it is the vx nerve agent, which is a chemical weapon. >> it's one of the most lethal creations that man has ever come up with. >> reporter: vx is odorless and tasteless. a tiny amount will trigger uncontrollable muscle contractions, causing first confusion, drowsiness and nausea before leading to death or paralysis. and it killed kim jong-nam, half-brother of north korean leader kim jong-un in minutes. just after he saunters into the airport, a woman lunges at him from behind, rubs his face for an instant, and moves quickly away. another woman was also involved. kim immediately reports to

airport authorities, gestures to his face, and soon collapses. experts say the assassins were risking their own lives by handling the vx so openly. >> that they held a rag over his face and rubbed it in, that individual is putting themselves massively in harm's way. >> reporter: both women survived, though one was vomiting after the attack. the airport now being decontaminated. vx can last for days. the brazen assassination, the latest in kim jong-un's bloody reign, taking out his estranged half-brother, a possible rival. and his regime, estimated to have up to 5,000 tons of chemical weapons. >> now that investigators know what killed him, will they be able to trace the source? >> reporter: there's a very good chance of that. teams of chemical weapon investigators will look at the

swabs from his eyes and may get a chance to see where it came from. this may be a real window on the north korean capabilities. >> thank you. back here at home. severe storms hitting at this hour, the system moving from the midwest to northeast. weather alerts up from iowa all the way to the east coast. alex perez from indiana. >> reporter: tonight, treacherous driving in the midwest. whiteout conditions on the move, heading east. in southern minnesota, tractor trailers overturning. people pushing cars. authorities urging residents to stay off the roads. >> today would be a good day just to stay home. and if you do travel make sure you plan ahead. >> reporter: more than a foot of snow now on the ground in rochester. this, as nearly 30 million are at risk for damaging winds and tornadoes.

up to quarter-sized hail already in indiana, all from a system that claimed at least four lives in separate crashes in utah. and in idaho, this chain reaction crash involving two school buses on a snow-covered road. nearly 60 fifth-graders on board, one student taken to the hospital. and david, here in indiana and parts of the ohio valley, they are bracing for a long night of powerful storms and even the possibility of tornadoes. david? >> alex, thank you. let's get right to rob marciano with a track of the storm. >> reporter: the storm is bumping into some big-time heat, so a volatile situation. ohio, michigan, very rare to get thunderstorms this far north. and meanwhile, the backside of the blizzard still going. the snow will wind down tonight, show showers into chicago. and look at the rain and thunder

along i-95. the cold front does come through, and it does get cold. temperatures will feel like the teens come sunday, so we hope the east enjoys today's warmth. >> thank you. and president trump taking aim at the fbi. amid new questions about what the white house asked for from the fbi involving investigations into possible contact with the russians. here's jonathan karl. >> reporter: today, president trump basked in the glow of a friendly crowd. >> i love this place. love you people. >> reporter: then he slammed his own top law enforcement agency for failing to stop what he called illegal leaks. "they can't even find the leakers within the fbi itself," the president tweeted. "classified information is being given to media that could have a devastating effect on u.s. find now."

the president is especially outraged at a "new york times" story quoting officials alleging repeated contacts between the trump campaign and russian intelligence. over the weekend, chief of staff reince priebus said the story was nonsense. >> i've talked to the fbi. i know what they're saying. >> reporter: now, the president is furious about new reports priebus pressured the fbi to knock the story down. such pressure could violate longstanding policy prohibiting white house interference in ongoing investigations. >> i'm against the people that make up stories and make up sources. they shouldn't be allowed to use sources unless they use somebody's name. >> reporter: but ironically, the white house itself today organized a briefing for reporters on the story and insisted that officials be quoted anonymously. one top white house official at the briefing, who insisted his name not be used, said there was no pressure on the fbi.

in fact, the official said, fbi director james comey dismissed the "new york times" report into the russian connection as, quote, "total garbage." director comey was at the white house just last month, praised by the president. >> he's become more famous than me. >> reporter: but when chief of staff priebus asked comey if the fbi would publicly dispute the "new york times" story, the fbi director said he could not do that. none of this seemed to matter to the crowd at cpac, the largest annual gathering of conservative activists. trump skipped it last year. this year, a triumphant return. how is this cpac different from previous cpacs? >> i mean, just the buzz and excitement, and we're winning. we're in the white house. i mean, it's just exciting. >> reporter: this hasn't always been trump's crowd, but it sure was today. >> the core conviction of our movement is that we are a nation

that put and will put its own citizens first. >> all: usa! usa! usa! >> and jon with us live from the white house tonight. we understand there was a press briefing today, but only some news organizations were allowed in? >> reporter: some of the largest news organizations in the country, denied access to the briefing. while smaller conservative outlets were allowed in. it's highly unusual to exclude major news organizations that cover this building every day. what the white house said, is that they wanted to do a smaller, more intimate briefing because the president was giving a major speech today. this meeting was held in sean spicer's office, a smaller area.
