why he got down on his knee not once but twice. "nightly news" begins right now. from nbc news world headquarters in new york, this is nbc "nightly news" with lester holt. good evening. great to have you with us on this monday. there are two big stories playing out this evening that are putting key parts of the trump agenda on the line including the u.s. supreme court allowing parts of the president's travel ban to go into effect for now. but we start with a major new wring until the fight to win passage of a healthcare bill in the senate. the independent congressional budget office has crunched the numbers and the republican plan tonight it estimates 22 million americans could lose health coverage over the next two years. already facing mounting reluctance within their own party republican leaders are still insisting on getting a vote this week. our coverage starts with nbc's kasie hunt.

>> reporter: health care for 22 million people hanging in the balance. that's how many could lose coverage in the next decade over the senate healthcare bill. according to the congressional budget office. for the senators deciding how to vote, it's millions more uninsured than many had hoped. >> if you're on the fence, i'm not so sure this report helps you much. >> obviously, it's not good news, and so it will have to be a factor. >> reporter: brian schatz tweeting cbo confirms this thing is a bleep sandwich. the cuts to medicaid will help save $321 billion over the next ten years. that gives mitch mcconnell more room to negotiate even as he faces protest in the ranks. >> i'd like to delay the thing. no way we should vote on this next week. >> reporter: ron johnson is one of five republicans who say they'll vote no without changes. only three no votes would sink the bill. and many are still undecided. are you a yes on the

healthcare bill vote? have you decided yet? >> no, i read it this weekend. there's still focusing on it. >> reporter: the president on the phone this weekend with conservatives and moderates. a delicate balancing act. >> you move it this way and this group doesn't like it. you move it a little bit over here, a very narrow path. >> reporter: the clock is ticking. after today's score, tuesday and wednesday will see last-minute changes, then votes on democratic amendments likely late into the night. before, if all goes to plan, final passage thursday or friday. but today more signs of trouble. the american medical association saying the republican plan violates the first rule of medicine -- do no harm. with no democrats on board -- >> republicans would be wise to read it like a giant stop sign. >> reporter: republicans anxious to fulfill a promise seven years in the making. now, the arm twisting begins in earnest. republican leaders might be able to spend more to combat the opioid crisis, for example, and vice president mike pence

has invited four conservative senators to his residence tomorrow night to try to convince them to get on board. lester? >> kasie, thank you. as you noted among the proposals in the bill are steep cuts to medicaid over the long term. supporters say the changes are necessary to save the program. but some healthcare providers say the effects would be devastating to the 1.4 million americans living in nursing homes. nbc's gabe gutierrez has a closer look. >> reporter: these days jane hale is worried. >> it's really scary because you don't know what's going to happen. >> reporter: the 74-year-old has been living in this nursing home for 11 year, first on private insurance, now on medicaid. how crucial is medicaid to your life? >> if i didn't have medicaid, i don't know where i'd go. my children do not have room for me. they have families of their own. >> reporter: but the senate healthcare bill with its changes to medicaid could hit nursing homes especially hard.

>> two-thirds of residents in long-term care facilities rely on medicaid as their main source of funding. >> reporter: the costs are already staggering and expected to grow 6% a year. $389 billion now to $650 billion in a decade. many republicans say slowing the growth of medicaid is crucial to saving it. >> we need that in order to make the program viable and to deal with these massive deficits and the mounting debt that we have. >> reporter: medicaid covers 20% of americans. >> many people that are perfectly middle class or even upper middle class when they retire, by the time they find themselves 80 or 85, they spent down and they don't have any funds. >> i think that the people that are trying to do the cuts ought to stop and think what if it was their mother, where would you want them to be? >> reporter: a question she hopes washington will consider. gabe gutierrez, nbc news, illinois. and as we previewed at the top

of the broadcast, the other big story tonight, the battle over president trump's travel ban has reached the supreme court, which has agreed to hear president trump's appeal of lower court rulings against the ban and the court said the government can begin enforcing at least part of it in the meantime. it's a partial victory for the president. we get details from our justice correspondent pete williams. >> reporter: for the first time in five months, a legal win, at least a partial one, for president trump after a series of setbacks that blocked enforcement of his executive order on travel. the court granted his appeal of two lower court decisions against it and said some of it can now be enforced. a 90-day pause on issuing visas for travel from the u.s. from six muslim countries associated with terrorism. the white house insists that to protect national security it must use the pause to check background information provided by those countries on visa

applicants. president trump adding i cannot allow people into our country who want to do us harm. the court was unanimous on agreeing to take up the president's appeals, but by a vote of 6-3, it agreed with the lower courts that the travel ban can mott be enforced against anyone seeking a visa who has a close relative here or wants to come here to study or teach or coming here to accept a job offer. that means anyone in those categories can still apply for a visa. that's why the challengers say this is a legal win for them. >> president trump, you can't enforce the refugee ban, you can't enforce the muslim ban against those people who are connected to the united states, which has always been the heart of our challenge. >> reporter: three of the court's conservatives, thomas, alito and gorsuch, said they would have allowed the entire executive order to be enforced with no exceptions. groups sponsors refugees from the six countries say it's not all good news for them. >> i think we're most concerned about individuals who perhaps do not have any ties tore family relationships to the

united states and what it means for them. >> reporter: the travel restrictions last only 90 days and the court won't hear the case until october. by then the case could be dismissed as moot, no longer a live controversy. the court ruled that states cannot refuse to give taxpayer money to churches, especially for programs of general public benefit like making playgrounds safer. and the court said it will hear an appeal in the fall from a denver baker who says that having to bake cakes for same-sex weddings violates his religious freedom. >> pete williams at the supreme court, thank you. president trump today raised eyebrows by leveling explosive new allegations against his predecessor. while mr. trump acknowledged russia's meddling in the u.s. election, he placed blame on mr. obama accusing him of purposefully doing nothing about it. nbc news white house correspondent kristen welker has details. >> reporter: tonight president trump unleashing a new tactic on the russia

controversy, put ointing the finger at president obama. >> reporter: while never formally acknowledging that russia meddled in the race, now the president can't stop talking about it. writing the real story is that president obama did nothing after being informed in august about russian meddling, alleging president obama colluded or on instructed without evidence. this after a "washington post" report showed that he was concerned about the appearance of helping hillary clinton. but one obama official saying i feel like we sort of choked. mr. obama did take some action, a warning to president putin and a new round of sanctions after the election. president trump seemed to be egging russia on about hacking clinton campaign e-mails. >> russia, if you're listening, i hope you're able to find the 30,000 e-mails that are missing. >> reporter: why is he now blaming his predecessor? how can you accuse president obama of on instructing when he was egging russia on. >> he was joking at

the time. >> reporter: he was joking? he said that as a candidate, and he was pressed on that during the press conference over and over. >> i understand. and the i think the idea was that you had hillary clinton with a secret server, that's probably a bigger concern right now in terms of what they were doing and the lack of security that they had. >> reporter: tonight we've also learned russia's ambassador to the u.s. is returning to russia. u.s. officials say it's a long-planned move that now predates his highly scrutinized conversations with trump aides. there's new information out tonight on an air scare as investigators in australia look into what caused an engine on an air asia flight to come apart while the plane was in flight, shaking the plane violently for the better part of two hours until the crew could make it over land to make an emergency landing. here's nbc's tom costello. >> reporter: for the passengers on board airasia 237, a terrifying flight as a malfunctioning engine violently shook the plane from nose to tail. the captain appealing

for prayers and calm. >> our survival depends on it. >> it's not something that i would have done. my point would have been to reassure the passengers that everything was under control. >> reporter: the airbus a-330 had departed perth, australia, for malaysia. suddenly at 38,000 feet, a compressor fan blade in the left side engine fractured and broke apart spewing pieces of metal throughout the engine and causing significant damage. this photo shows the missing blade and the damage to the surrounding blades. the crew quickly shut the engine down, but the air flow caused the fan to continue spinning sending violent vibrations through the plane as it flew safely back to perth on a single engine, something all twin engine planes are designed for. >> thought we were going to go down. >> reporter: airasia says it's conducting an investigation with engine manufacturer rolls royce. engine failures are rare and usually not

as serious as last october's explosion and fire on an american 767 in chicago. everybody got off safely. among the questions tonight, why did the pilot fly all the way back to perth rather than divert to a closer airfield. tom costello, washington. now the unfolding triple threat gripping much of the country this evening from texas to california. across several states, wildfires are raging, a deadly heat wave is blanketing millions and rivers are overflowing from snow melt. perhaps the most serious threat may be the fires kicking out of control as the sun goes down and the wind picks up. nbc news national correspondent miguel almaguer is in the fire zone tonight. >> reporter: this is what firefighters call a recipe for disaster. fast moving flames fanned by hot winds torching through dry terrain. >> oh, my god. look at that. >> reporter: residents racing to evacuate just outside los angeles late sunday. the inferno within

feet of destroying an entire neighborhood. >> it's pretty scary, thinking that, you know, your house could burn down. >> reporter: tonight 21 large wildfires are exploding across seven western states. the biggest and most destructive, in utah where more than a dozen homes have been lost. >> you feel so bad for the ones that have lost already. i just can't believe it. >> reporter: fueling fire, record breaking heat. today 16 million are under advisories. this day ten of a deadly heat wave. at least 14 children killed in hot cars this year including two in texas over the weekend. and now the scorching temperatures are triggering another problem. rivers raging from snow melt. near sacramento, this daring rescue. a swimmer stranded, no time to spare. tonight, across the west, a triple threat, ferocious flames, killer heat and

dangerous currents. with tens of thousands of acres scorched across this region, temperatures in some areas remain in the triple digits. the homes in this neighborhood were teetering on the edge of disaster. the good news, the temperatures here will drop in the coming days. the bad news, the winds will remain a serious problem. lester? >> miguel almaguer tonight, thank you. tonight several people are still missing as divers search for bodies after a deadly tourist boat disaster in colombia. a ferry packed with over 150 people capsized. the tragic scene captured on camera. gadi schwartz has the latest. >> reporter: screams of panic as a ferry four levels high loaded with 150 passengers quickly sinks. today the stories of survival are harrowing. >> translator: i grabbed my partner by the hair and began swimming. i couldn't see anything. >> reporter: cell phone video capturing this sinking ferry dropping two floors under water. in the chaos, 13

missing and 7 dead including this woman's mother. survivors say they heard an explosion near the bathrooms just minutes into the cruise. >> translator: this did not take place because of overcrowding. the boat sank very quickly. this leaves us with a great question mark. >> reporter: three years ago a south korean ferry sank killing more than 300 people. that captain sentenced to life in prison for negligence. tonight in colombia, rescuers search for the missing. still no word on whether charges will be filed against the captain who survived. his daughter among the dead. gadi schwartz, nbc news. we got more to tell you about tonight. still ahead, probiotic supplements. they promise everything from better digestive health to cures for disease, but can they really do all that?
