glimmers of progress, republicans scheduling a morning huddle to strategize. but then -- >> it just says postponed. >> reporter: so it's 9:00 a.m. and house republicans were supposed to be meeting right here to discuss the path forward on health care, but as you can see, the lights are out, the meeting room is empty. the meeting's canceled. >> mr. speaker why cancel the meeting? >> reporter: the house speaker stuck in between the opposite ends of his own party, with the most conservative members digging in. >> what's the deal? >> not yet, and we don't want to get overly optimistic. >> i will proudly vote no if the bill continues as it is bad for america. >> reporter: at 11:30 a.m., those conservative hold-outs are summoned across town. sitting around a white house conference table, the president and vice president personally negotiating changes. the conservatives demanding revisions to lower premiums. and they want to scrap requirements that insurance plans cover basic health services, like maternity care, drug and mental health treatment, wellness checkups

even ambulances. but those changes sounding alarms for moderate republicans, putting their support for the bill at risk. back on the hill, the speaker tackles that resistance. concerned members spotted leaving his office. >> are you getting closer? >> we're going to get it done. >> we're working. >> reporter: but still no agreement. inhehiteuse, rnconservativeg s say the close chief still has not clinched the deal. >> there are not enough votes as of 1:30 today. >> what are the concessions that the president is offering? >> there were no new concessions. >> reporter: despite the storm clouds over capitol hill, the white house sounds sunny. >> is there any plan with the bill does not pass tonight? >> it will pass. >> reporter: meeting with truckers, the president is confident. tonight is the night. >> today, the house is voting to repeal and replace the disaster known as obamacare. we'll see what happens. it's going to be a very close vote. >> reporter: but just minutes

later, house leaders pull the plug, canceling the vote. after delivering the president his first major legislative setback, the man holding the cards, the chair of the freedom caucus insists they are working in good faith. >> i am still a know at this time. i'm desperately trying to get to yes, and i think the president knows that. >> and mary bruce joins us from capitol hill where she has been so busy. mary, this just in. the white house are now insisting there will be a vote tomorrow morning, and this bill will pass, but what about republican leaders in congress? are they as confident? >> reporter: tom, tonight, republican leaders publicly insist they are optimistic. the house speaker is calling a meeting right now. negotiations are likely to continue throughout the night. they are hopeful they can still strike and deal and have a vote as soon as tomorrow, but right now, it's unclear how, tom. >> the story changing by the hour. thank you so much. let's go to the white house now. cecilia vega standing by, and we

just heard mary's story, president trump. he said the vote was happening within minutes. news broke that house leaders had called it off. is there a disconnect between the white house and capitol hill? >> reporter: yeah. well, tom, what i'm hearing from sources who are close to the negotiations is there is a definite learning curve for the white house that the president and his team as you know, largely outsiders aren't accustomed to the realities of governing this process. the rounding of the votes is takiing longer than they realizd it would, and i'm told the president has been working hard behind-the-scenes to get the votes on board and he has been making phone calls and again on the phone at 6:00 p.m. to round up the votes. he has had four sets of meetings in the last two days. as you said, the white house is confident this bill will pass. >> working around the clock, determined to get that deal done. thank you. next tonight, isis has taken responsibility for that terror attack in london. the death toll rising again today. crowds gathered for vigils.

take a look this evening to remember the lives lost. one of those, an american from utah, celebrating a milestone anniversary. there with his wife. abc's terry moran reporting from london tonight. >> reporter: tonight we are learning more about the man who attacked the heart of london. khalid masood, 52 years old. british-born. believed to have acted alone, though he was long known to authorities here as an islamist radical. police now executing raids across the country, arresting eight, and seizing evidence. the investigation centering on the city of birmingham in the north of england, where masood was living, and abc's alex marquardt is there. >> reporter: this house is masood's last known address. it was raided overnight by police. one neighbor identified masood from a picture of the attack, saying he was a normal family man who like to take care of his garden, but who left abruptly just after christmas. >> reporter: outside parliament today, where the rampage happened, forensic technicians on their hands and knees, painstakingly searching for

evidence. london was a city defiant. parliament was in session. the westminster bridge reopened the afternoon. the attacker sped the 800-foot length of this bridge, up on the sidewalk much of the time. look how narrow it is. his suv would have taken up most of it. he ran over dozens of people. one woman going into the water. that surveillance video shows the car barrelling on, crashing into the railing, surrounding parliament. masood then getting out, armed with two knives,charged the main gates, fatally stabbing a police officer,finally shot down himself as he tried to attack other officers. the murdered police officer, 48-year-old keith palmer, married and the father of a 5-year-old girl. also killed, aysha frade, on her way to pick up her daughters from school. and a man taken off life support tonight, and an american, kirk

cochran, 54 visiting london with his wife, melissa, celebrating their 25th wedding anniversary, walking along the westminster bridge. >> he did live his dream, and not a lot of people get to do that. >> and kirk cochran's wife, melissa surviving and recovering in a hospital tonight. isis has claimed responsibility for this attack. british authorities still describing it though as a lone wolf? >> reporter: that's right, tom. they say while isis claims him as a soldier of the islamic state, they say he acted alone, and they are dinging through his long history of radicalization, but they don't believe he has associates who might be on the loose preparing a follow-on attack. >> terry, thank you. back here at home now for an apology from a key member of congress. devin nunes went public with a new claim that u.s. intelligence

intercepted communications with trump associates. nunes took that information to the immediate wrmedia and then house before telling his own committee. abc's chief white house correspondent, jonathan karl, with the growing backlash. >> reporter: president trump is dismissing fbi director james comey's blunt statement that there's no evidence to prove his wiretapping allegations. asked if comey's assessment takes away from the credibility of his unsubstantiated tweets, the president told "time" magazi magazine, "no, i have articles saying it happened." a lot of information has just been learned, and a lot of information may be learned over the next coming period of time. we will see what happens. >> reporter: devin nunes, the republican chairman of the house intelligence committee, who concedes there was no actual wiretapping of trump tower, still tried to give the president a little political cover yesterday by saying this -- >> i recently confirmed that on numerous occasions the intelligence community

incidentally collected information about u.s. citizens involved in the trump transition. >> reporter: nunes, who is supposed to be leading a bipartisan house investigation into russian interference into the election, took the extraordinary step of going to the white house yesterday to personally brief the president on information he obtained. he's taken fire for that, including from fellow republicans. >> i think it's most appropriate for the committees to work independent of the white house, not next to the white house. >> reporter: in fact, nunes briefed the white house before even briefing the other members of his own committee. today he apologized. >> at the end of the day, you know, sometimes you make the right decision. sometimes you make the wrong one, but you have to stick by the decisions you make. >> reporter: but the top democrat on the committee questioned whether nunes is now simply too politically compromised to lead the investigation. >> we can't have our chair acting as a surrogate for the administration. he has to either have the surrogate role or the chairman

role but he can't do both. >> and jon karl joining us live now from the white house. and jon, tonight, even some republicans are questioning whether congressman nunes is the right man to lead this investigation? >> reporter: well, tom, from the beginning, congressman nunes faced questions about his independence. after all, he was on the executive committee of the trump tran igs, and now john mccain said with nunes' behavior and the behavior of his democratic counterpart is bizarre and disturbing. mccain wants to see a brand new committee set up that can do this in a bipartisan fashion. >> jon, thank you. tonight, congress is facing another shoot down. chuck schumer says his party will filibuster the confirmation of nominee, judge neil gorsuch, because his originalist interpretation of the constitution is out of step with modern concerns, but mitch mcconnell vowed he will be

confirmed. next to ukraine and the cold-blooded killing. ukraine's president calling it an act of state terrorism by russia. laying there on the street in the middle of the day. just a few months ago, he left russia with his wife and young son, and now he is the latest victim of a violent end. abc's brian ross has the story. >> reporter: the graphic pictures tonight show what us officials believe is the latest example of the long arm of vladimir putin. police surround the body of a member of the russian parliament, dennis voronenkov, shot dead this morning on the streets of the capitol city kiev after defecting to ukraine and publicly criticizing the russian president. just last month, voronenkov told a reporter for a tv network funded by the u.s. aimed at russia, that he accepted his fate as a putin critic. a kremlin spokesman tonight denies any role in the murder, but the president of ukraine is

calling it russian state terrorism on orders of putin. just two days ago, another putin critic, a russian lawyer was thrown out of the fourth story of his apartment building and critically injured. under the rule of russian president putin, more than a dozen critics have been targeted for assassinations. lawyers, businessmen, journalists. based on his public comments, none of it has seemed to bother president donald trump. >> putin is a killer. >> a lot of killers. you think our country is so innocent? >> reporter: a rush opposition told me that putin's critics counted on the u.s. to help stand up further russian president. >> everyone against him must be very careful. be afraid every minute. it's completely impossible for me. >> reporter: one year after that interview, he was dead. shot down under heavily guarded moscow bridge near the kremlin. >> we thank him for that report.

next, an arrest in israel. he was accused of phoning in threats across the u.s. and elsewhere. the suspect is jewish and was rejected by the israeli army facing questions about his mental health,but his motive is unclear. back here at home in new york city, an army veteran who police say is an admitted white smell cyst has been charged with murder as a hate crime in the stabbing death of a black man he chose at random. prosecutors say he told police that was only the beginning. abc's gio benitez with the latest. >> reporter: tonight, disturbing new allegations about the 28-year-old army vet police say was caught on video moments after stabbing and killing 66-year-old timothy caughman, on monday night. james jackson facing a judge today, looking angry, as prosecutors called the murder "a hate crime," most likely an "act of terrorism," adding that jackson considered this murder "practice before going to times square to kill additional black

men." in. >> it's well over ten years he has been harboring these feelings of hate towards blacks. >> reporter: police say jackson traveled from baltimore to new york. that he "had stalked numerous potential victims" and "was angered by black men mixing with white women." jackson turned himself in, admitting he's a white supremacist, police say, telling them where to find the 26-inch sword used to kill caughman. new york's governor tweeting he's asked authorities to investigate whether this senseless murder is "part of a larger pattern." jackson's attorney hinting at an insanity defense -- >> if the facts are anything near what the allegations are, then we are going to address the obvious psychological issues that are present in this case. >> reporter: and tonight jackson charged with murder as a rate crime. he's pleaded not guilty. prosecutors say they're considering and expecting to file even more charges. >> a disturbing and bizarre case. thanks so much. there is much more ahead on "world news tonight" this
