good tuesday morning to you. we begin with breaking news in the deadly attack on a russian subway. >> moments ago we learned that the bomber has been identified. right now we're told at least 14 people were killed and dozens wounded in the blast in the major european city which occurred as the train passed between two downtown st. petersburg subway stations. no group claimed responsibility but two hours after the blast authorities found and deactivated another bomb at a nearby station. >> reporter: investigators announced moments ago that a suicide bomber is believed to have been behind the blast. overnight the bombing suspect was identified as a russian citizen born in a former soviet republic. earlier we spoke with abc's patrick reevell in st. petersburg.

>> in many ways we've all been waiting for something like this to happen because russia is so engaged at the moment in syria and in a war against radical islamic terrorism there while backing bashar assad's government. many of the fighters in syria do come from central asia. >> and st. petersburg, which is russia's second largest city, is starting three days of mourning for the attack victims. a live look right there, and you can see the growing memorial. this is near the entrance to one of the stations, and this has been a scene that we've seen all throughout the overnight hours with people coming there and paying their respects. now, president vladimir putin was in the city when it happened and added flowers as well to the memorial last night. he is a native of that european city, st. petersburg, and he also spoke with president trump who condemned the attack and offered condolences. we're going to continue to track these breaking developments from russia. back here at home, the bitter partisan fight over president trump's pick for the supreme court is poised to take a historic turn. >> yeah, as a vote on judge neal gorsuch heads to the full senate democrats picked up enough support to stage a filibuster but republicans are armed with

the so-called nuclear option ready to lower the confirmation threshold to a simple majority. abc's lana zak has the latest from washington. lana, good morning. >> reporter: good morning, kendis and diane. you know, neither side right now looks like they are willing to compromise. and some democrats have expressed particular concern about judge gorsuch's previous history in interpreting the law, but for many this is purely political. the senate is in a tailspin and it doesn't look like either side is willing to blink. >> i cannot support this nomination. >> i will not, i cannot support advancing this nomination. >> i will not support judge gorsuch's nomination. >> neal gorsuch will be confirmed this week. >> reporter: republicans and democrats are headed for a collision course that will likely end with republican majority leader mitch mcconnell employing the so-called nuclear option, changing the senate rules forever. >> we're headed to a world where you don't need one person from the other side to pick a judge. and what does that mean? that means the judges are going

to be more ideological, not less. >> reporter: a handful of democrats have said they will support president trump's pick, judge neal gorsuch, but the vast majority are supporting a filibuster. >> as senator cornyn previously remarked, there has never been a partisan filibuster of a supreme court nominee in history, and while technically correct, i question what a seven-month refusal to hold a hearing or vote is if not the longest partisan filibuster on this committee. >> reporter: senate democrats are still smarting over the previous actions of mcconnell blocking president obama's nominee, judge merrick garland, from consideration for nearly a year, but the message for many republicans now is as simple as get over it. >> if they will filibuster neal gorsuch, they will filibuster any nominee from a republican president. >> reporter: and the white house warned that the american people will be watching to see which senators try and stand in the way of president trump making progress. clearly, diane and kendis, that

could be seen as a threat to those democratic senators who are facing re-election in states most recently won by president trump. >> that's right, many will be watching those more local elections going on. lana zak live in washington for us. lana, thanks. we're learning some more details about jared kushner's trip to iraq. the president's son-in-law and senior adviser met with the iraqi prime minister to discuss the fight against isis and get a firsthand assessment of the situation on the ground. he was briefed by top military advisers with talks focusing on the ongoing battle to retake the city of mosul. and white house officials have met separately with moderate and conservative republicans as they look to try to revive the failed republican health care bill. members of the house freedom caucus who sat down with vice president mike pence last night say that he presented a new offer that includes waivers for certain coverage requirements. the chairman of the caucus said he's encouraged by the proposal but there's no deal yet. turning now to the growing crisis in colombia, three days after a deadly mudslide, the

death toll has now surpassed 270 as the first funerals are being held for the victims. hopes are now fading among rescuers who are still scrambling to try to find survivors. days of torrential rains triggered an avalanche of mud, water and debris that swept away entire neighborhoods. at least 2,500 people are now homeless. well, as for the weather in this country, the worst is over for the southeast but only starting for the northeast. the system has moved off the southern atlantic coast, but it's bringing a round of heavy rain to the northeast overnight as you can see there. it should be gone by the morning rush hour but should make things a little rough in parts of new york. before leaving the south the storm caused damage in northern georgia including tearing off that roof. that's off a fire station there. 11 tornadoes were reported in the state. quite a few scenes there. and quite a few scenes overnight as well in glendale, arizona. the big sports headline, the university of north carolina or the university of champions, as michael jordan calls them,

they're the new champs of college basketball. >> they are, indeed. abc's t.j. holmes watched all the action from the stadium in arizona. >> reporter: well, kendis, diane, we were going to either see something that we've never seen before or something that we've seen relatively often. well, the latter ended up being the case, north carolina picked up another national championship trophy while gonzaga, which was making its first ever appearance in the final four, they came up short in what was really kind of an ugly game, a lot of whistles, a lot of fouls, some ugly play. coach roy williams admitted right after the game really that both teams didn't play well but you know what, all that doesn't matter at the end of the day. north carolina picks up another national championship, and they complete what they were calling all year their redemption tour after they had their hearts broken last year on the last-second shot against villanova. well, they come back. the whole year was dedicated to getting back to this point and winning the national championship, and as they say now, the redemption tour is complete. the tar heels once again your national champ. guys.

>> t.j., thanks. >> i got a sense he was almost screaming during the game. lost his voice. >> voice is a little hoarse. maybe after the game with all the cheering. the tar heels' win sets the stage for this drone video showing thousands of students and fans running toward a celebration in the streets of downtown chapel hill. >> yeah, plenty of them ignored warnings about lighting victory bonfires. there were no reports of any serious trouble. we're going to have much more about the game a little later on on espn. congratulations, tar heels. >> they came so close last year. >> yeah. >> now they brought it home. first time in eight years. >> yep. all right, still ahead, the common painkiller that can reduce the risk of certain cancers. and an explosion launching a boiler through a roof. it lands on another building down the street. the deadly blast caught on camera. plus, a teenager survives a shark attack by fighting it off. this morning her mom is talking about the very close call.
