>> ninan: good evening. i'm reena ninan. what's next? that's the big question following president trump's stinging defeat this week on health care. mr. trump, who is spending the weekend in washington, wants to move on to the next item on his to-do list-- tax reform. but haze hiz failure to rally republicans behind a plan to repeal and replace obamacare has raised questions about his ability to clear legislative hurdles. we have two reports tonight on what's next for health care and the president beginning with chip reid. >> reporter: on twitter today, president trump tried to rally his deeply disappointed surptses. "bawsm will comploat," he wrote, and we will get together a plan for the people. do not worry." but an explosion of obamacare is far from guarantee. after cancelling the vote on the republican bill friday, house speaker paul ryan said this: >> obamacare is the law of the land. it will remain the law of the land until it's replaced. >> reporter: he suggested that the house will return to health care but gave no hints too when

that might be. . >> it is not the end of the story because i know that every man and woman in this conference is now motivated more than ever to steppure our game to deliver on our promises. >> reporter: but that will take cooperation from the archconservative house freedom caucus, which gave president trump a standing ovation thursday-- >> do you have the votes. >> reporter: then on friday played the leading role in the president's humiliating defeat. they opposed the bill because they say it doesn't go far enough to repeal obamacare. >> in my judgment, this was the killing of bad legislation in which case it would be considered a good day for america. >> reporter: alabama congressman mo brooks is eye freedom caucus member. >> i'm optimistic that we'll do better in the future having learned from this experience. >> reporter: house democratic leader nancy pelosi literally jump forward joy after the republican bill died. she says it's time for the republicans to allow democrats s to have a role. so far, they've been almost entirely excluded from the process. >> we have a responsibility to

find common ground. >> reporter: democrats are now worried that the trump administration will use its control of the federal health care bureaucracy to try to make sure that obamacare does fail, an eventuality that they say would be devastating for millions of americans, democrats and republicans. reena. >> ninan: chip reid, thank you. now, errol barnett is at the white house with a look at the next goal in president trump's economic agenda-- an overhaul of the personal and corporate tax system. >> we were very close, and it was a very, very tight margin. >> reporter: after failing to close the deal to repeal and replace obamacare, president trump is moving on to reforming the tax code. >> would say that we will probably start going very, very strongly for the big tax cuts and tax reform. that will be next. >> reporter: mr. trump was convinced by g.o.p. leadership to attack taxes after health care so any budget savings reached through cutting obamacare could have paid for tax reform. >> the savings that you achieve

through obamacare, which we were going to save many billions of dollars, can be used then towards the additional pot for tax reform. >> reporter: but now that republicans have been dealt their first major legislative loz, speaker ryan acknowledges tax reform will not be easy. >> ythis does make tax reform more difficult, but it does not in any way make it impossible. >> reporter: ryan's house conference is split between moderate republicans and the more conservative and vocal freedom caucus. president trump steered clear of criticize anything of them. >> i like speaker ryan. he worked very, very hard. a lot of different groups. he's got a lot of factions. >> reporter: republican senator john mccain, who acknowledged he has yet to meet with president trump, was asked how the new commander in chief could be more effective? mccain said reach across the aisle, listen to advisers and... >> and i guess third of all, stop tweeght.

tony dokoupil sorts it out for us. >> it should be known that there's a possibility that this child-- >> reporter: police in washington, d.c. are rushing to contain a crisis of fear after a new policy of publicizing missing young people set off a panic. >> we can't go nowhere by ourselves. we can't do nothing because we have to be worried about somebody trying to take. >> reporter: more than 500 children and teens have gone missing in the nation's capital in 2017, but d.c. police say this number is actually lower than in years past, and there is no new evidence of kidnapping or human trafficking. police believe most are runaways. >> but the disturbing fact that we all need to be aware of is that we do have that many kids that go missing in our city, and it's been that way for a long time. >> reporter: at a town hall this week, acting police chief peter newsham said the department is trying to draw new attention toon old problem. >> one missing person in d.c. is

one person too many, and especially when we're talking about our young people. >> reporter: it was in hopes of finds manager missing minors that she recently instructed the d.c. metro twitter account to share every case deemed critical, but the site of more lost children on the account, including a half dozen girls, shocked the d.c. community spurred by social media, spread by celebrities and the hashtag #missingdcgirls. african americans make up just 13% of the population, but black children and teens go missions at nearly three times that rate. nationally, 38% of missing juveniles are black. and on friday, d.c. mayor muriel bowser launched an effort to address this problem, including assigning more officers to each

case and expanding programs aimed at runaways. >> ninan: thank you, tony. well, a ban on carry-on laptops and tablets aboard certain u.s.-bound flights took effect today. the temporary restrictions affect direct flights to the u.s. from eight countries in the middle east and north africa. passengers now have to check most electronic devices larger than a cell phone. security officials say terror groups may be planning to target passenger jets with explosives planted in larger devices. well, authorities are investigating what caused a small plane to crash in suburban atlanta friday. the plain plan, a cessna citation, went down between two houses, setting one on fire. the pilot was killed. everyone inside the houses got out okay. one of uber's self-driving cars has been involved in a traffic accident. this happened in tempe, arizona, where the vehicles are being tested. police say that a car driven by a human sideswiped the automated car after an illegal left turn. no serious injuries. in louisiana, a former law

may have been radicalized. >> i don't think so. but he look like aid normal guy. >> reporter: british police are now trying to figure out what triggered his deadly parliament rampage that killed four people and injured dozens more. masood started life as adrian russel ajao, a british-born kid who went to a christian school in kent where he played soccer. it's believed he converted to islam during doourg his several stints in jail. he was once investigated for extremism. but by 2017, at the age of 52, he had fallen off the radar. richard walton is the former london police head of counter-trump. >> a 52-year-old male, that is quite exceptional, and, obviously, there will be concern about how he was radicalized, was it through face-to-face contact with groups in the u.k., or was it contact via social media? >> reporter: birmingham is home to one of the largest

muslim communities in the u.k., and in recent years, the city has faced accusations of becoming a fertile recruiting grownd groundfor jihadis. one recent study found at least 50 men from birmingham had left to fight in syria. muslim leaders like mohammad afzal, from birmingham central mosque, fear the entire community could now face a backlash over masood's action. >> we condemn these terrorists. we are law-abiegd citizens and we should not be marginalized purely because some stupid person, some evil person has done this thing. >> reporter: saudi embassy statement says masood taught english in saudi arabia under a work visa or at least two occasions. police believe he acted alone in the attack, but it's unclear if he had help with planning. reena, at least two people are being questioned. >> ninan: jonathan vigliotti in london. thank you, jonathan. pope francis visited the northern italian city of mill an today. he met with families in a
