>> reporter: that was john mccain when he voted no on the last health care bill. today, he cited the same reservations, saying he could not "in good conscience vote for the graham-cassidy proposal. i believe we can do better working together, republicans and democrats." republicans were hoping mccain's close friendship with one of the bill's authors would sway him this time. >> i love him to death. >> reporter: but this latest g.o.p. repeal effort has beenjua rag. sor colorado's cory gardner... >> trying to get some more information on it. >> reporter: ...scrambling to figure out what it would mean for their states before next saturday's vote deadline. do you think you're going to be able to get as much information as you need by next week. >> we're working with the staff of bill cassidy and lindsey maaham. >> reporter: it would block some of the obamacare's funds to the state so they could set up their own coverage systems. but independent analyses show the bill would slash federal health care funding to about 35

states, most of them states that expanded medicaid under obamacare. five states stand to lose 30% or more. with mccain and kentucky's rand paul opposed, g.o.p. leaders can't afford to lose another senator. so today, the vice president turned up the heat on maine's susan collins, appearing at the white house with her state's governor to push the plan. >> this is not just a fresh start for america on health care reform, but it's also a fresh start for maine. or reporter: but collins was a ar before and appears to be leaning no this time because of what the bill could mean for medicaid recipients and people with pre-existing conditions. so, barring some major change, anthony, this bill, viewed as the g.o.p.'s last, best chance, is poised to meet the same fate na its predecessors. >> mason: nancy cordes. thank you, nancy. a california family is trying desperately to bring a relative to the united states from vietnam to save a life.

working on a replacement. margaret brennan has more about that. margaret. s reporter: well, until the president makes a decision, countries won't be notified as to exactly how these new travel restrictions will impact people. but what we do know is that the new rules go into effect after the existing six-country travel potnoifres this sunday.we d w,inotenti aallyte advance so they could update their security standards, and only around eight or so countries either refused or were unable to comply. so ndehonse ow tntresiheode has tand whether there are any exceptions-- people already in transit or with valid visas won't be blocked from entering the u.s., but those applying for new visas will be impacted. the trump administration really wants to avoid the type of chaotic roll-out that resulted from its first travel ban which totally blocked people from a number of muslim-majority countries. and, anthony, this time the

a.c.l.u. say they fear this is just a third attempt at a muslim ban, and they are going to scrutinize the language that the administration uses to justify this. red remember, this could have some influence on that pending asse before the supreme court. >> mason: all right, margaret brennan, thank you very much, margaret. a army blackhawk helicopter was hine today as it flewro dt bysecurity for the u.n. general assembly in new york city. the helicopter, from the 82nd airborne division, was struck over staten island. it's not known who was operating the commercial drone. the blackhawk landed safely in new jersey with a damaged rotor blade and dented windshield. an iraqi teenager was charged today with attempted murder in connection with last week's london subway bombing. the attack injured 30 people. 18-year-old ahmed hassan is accused of planting a bucket bomb made from materials he ordered online. also in london, it is uber and

but according to police, there were two sexual assault complaints against uber in 2016, the same number as black cabs. black cab drivers have fought against uber since it moved to edrope. they say uber is under-regulated and will put them out of business. >> our money's been cut, not by a lot, by about 10%, 20%, but it's been affected, yes, most definitely, yeah. d sa today, he's celebrating. >> oh, i'm going to take the day off. i was going to form a party. epwas going to go to the pub.r:n >> r ter says the city chose to side with a small group of people that wanted to limit consumer choice. ier will challenge this decision in court. already, more than 300,000 people have signed an online petition to keep uber on the road. anthony. >> mason: jonathan vigliotti with happy london cab drivers. thanks, jonathan.

the former presidential candidate.. pushing a complete overhaul, of the nation's health care system. good evening, i'm veronica de la cruz. i'm allen martin. it looked a bit like a rally from the 20-16 presidential race. but today-- senator sanders came to san francisco to sell his vision for universal health care. kpix 5 political reporter melissa caen says: he also slammed the republican' bill. melissa.. bernie sanders was here to speak at a convention of the california nurses assocaition. but the event was outdoors at the yerba buena center and members of the public crowded in to see the senator. [sot- sen. bernie sanders, d-vt] sxs bernie for melissa raw one(21)13:15:12 we're not gonna let you pass that horrific legislation [applause] stop the graham- cassidy act - that senator's message today in san francisco. he even gave estimates for how the republican healthcare bill would affect california. [sot- sen. bernie sanders, d-vt] sxs bernie for melissa raw one(21)13:16:33 in this state alone, if you can believe it, just in california, over 4 and a half million people would lose the health insurance they currently have. because other republican healthcare proposals failed, he seemed confident that graham cassidy can be beaten. [sot- sen. bernie sanders, d-vt] sxs bernie for melissa raw one(21)13:15:23 now we defeated a republican proposal that would have thrown 23 million americans off of healthcare. we defeated a republican proposal that would have thrown 22 million people off of healthcare, that would have thrown 16 million people

off of health insurance. and now, we are going to defeat another proposal which is even worse thhe previous ones. but defeating the republican healthcare bill isn't good enough - he wants a single payer system he calls "medicare for all" [sot- sen. bernie sanders, d-vt] sxs bernie for melissa raw one(21)13:20:11 our job is not just to prevent tens of millions of americans from being thrown off the health insurance they currently have. our job is to join every other major country on earth and guarantee healthcare to all as a right not a privilege. bonnie castillo is the associate executive director of the california nurses association. she says nurses see the problems with the healthcare system every day. and the solution a single payer system with no health insurance companies. [sot-bonnie castillo, asso. exec. dir. cns/nnoc] sxs bernie for melissa raw two(1)13:56:33 look they've had a long time, right? to provide for healthcare and they've really done a really, really horrendous job. this is even with people who have, right? that they can't afford to use it. what's it good for? the group is thrilles to have sanders - a champion of single payer care - speaking today. [sot-bonnie castillo, asso. exec. dir. cns/nnoc] sxs bernie for melissa raw two(1)13:51:44 we believe that bernie sanders - senator sanders - is a tremendous leader and we are committed to go all the way with him. other nurses we spoke to agreeed. we asked a nurse from maine if seeing sanders was the highlight of the convention so far.
