>>ninan: good evening, i'm reena ninan . millions of people in the deep south are in the path of dangerous weather. this was the frightening scene today as a tornado was spotted near woodworth, louisiana. tornadoes, flash floods, devastating winds, and hail are in the forecast tonight across texas, arkansas, louisiana, and mississippi. the southern storms cap a weekend of severe weather in the u.s. at least two people are dead. here's tony dokoupil. >> a suspected tornado toppled this mobile home near lafayette, louisiana on sunday, killing a mother and her 3-year-old daughter inside, police said. heavy rains, slashing winds, and hail as large as ping-pong balls hammered homes and vehicles from texas to mississippi. moist air - more typical of august than april - could bring flash floods with as much as 2 inches of rain falling an hour and strong tornadoes remained a risk into sunday night. in dallas, about 40,000 basketball fans had to make new plans - after the threat of violent storms forced ncaa

officials to cancel all outdoor events ahead of sunday night's championship game. worshipers at the real life church in chesapeake, virginia, meanwhile, had to find a new place to pray after a tornado tore through on friday. further north, april fool's day snowstorms were no joke from massachusetts to maine - where more than a foot fell. >> i'm all done. all done with this. ready for spring. ready for summer, yes. can't happen fast enough for me. >> this major severe weather outlook for the gulf states will last through tonight. and aside from tornadoes, hail reena, is the biggest worry, falling at speeds estimated as high as 100 miles an hour. >>ninan: you forget how hard this could be. thanks tony. the death toll continues to climb from devastating floods in colombia. heavy rains caused three rivers to overflow - unleashing what has been described as an avalanche of water and mud on the city of mocoa. more than 200 are dead.

many others are missing. mireya villarreal has the latest. >> emergency responders are looking through the rubble, tirelessly searching for survivors. >> this father is looking for his daughter luisa who's barely old enough to call out his name. she's just one of the hundreds still missing. the streets of mocoa, colombia were consumed by a wall of water late friday night. heavy rain triggered the overflow of three rivers and the flooding quickly turned into an avalanche of mud. aerials reveal the city's true devastation. the force of the mudslide knocking buildings over, sweeping cars away, and tearing families apart. $. >> this woman's friend was swept away by the current. her husband unable to hold on tight enough. colombia's president juan manuel santos toured mocoa and declared it a disaster zone. he says their hearts are with the families suffering and they are doing everything they

can to help. more than a thousand troops are on the ground searching, and recovering bodies. >> mi sobrina. >> this has become mocoa's weeping wall where a list of the confirmed dead continues to grow, many of them young children. during his sunday blessing pope francis said he'd be praying for the victims of mocoa. colombia's attorney general has launched an investigation with 45 investigators on this case. he wants to make sure corrective action is taken to prevent this from happening again. and reena, that is extremely important right now because more rain is expected in the next few days. >>ninan: mireya villareal, thank you mireya. it's going to be another busy week in washington with investigations continuing

on russian interference in the election and a senate showdown brewing over president trump's pick for the supreme court. mr. trump weighed in on some of the hot topics sunday on twitter. here's errol barnett. >> president trump began his day reminding supporters he still intends to repeal and replace obamacare, despite being defeated the first time around. he tweeted talks will continue "until a deal is hopefully struck." meanwhile, senate majority leader mitch mcconnell predicted a win for the president when his supreme court nominee faces senate confirmation. >> neil gorsuch will be confirmed this week. how that happens is up to the democratic friends. >> democrats are in no mood to cooperate, and may fillbuster the vote, which could delay it indefinitely. to maneuver around that, mcconnell would need to permanently change senate rules, a so-called "nuclear option" the president supports. >> look, when a nominee doesn't get 60 votes, you shouldn't change the rules, you should change the nominee. >> the senate is also gearing up for closed door interviews with witnesses in its investigation into russian election interference.

>> read my lips, "no." >> president putin this week denied playing any role and today the kremlin's spokesman, said there's no proof. >> we insist that any blamings that russia could have been interfering with domestic affairs of the united states is slander. and it has no, no evidence at all. >> republican john cornyn of the senate judiciary committee, disagrees. >> we want to understand the extent to which russia has attempted to influence and interfere in our elections and to undermine our democracy. >> president trump today tweeted, "the real story turns out to be surveillance and leaking - find the leakers. the ranking democrat on the house intelligence committee, adam schiff, sees behavior from the white house as suspicious.

>> whenever they see the president use the word 'fake,' it ought to set off alarm bells. the question is, of course, why? and i think the answer to the question is this effort to point the congress in other directions. >> today president trump played golf while discussing healthcare with senator rand paul. monday, mister trump hosts egpyt's president at the white house. later this week, mr. trump hosts china's president at his mar-a-lago resort in florida. reena, they're expected t >>ninan: thanks erroll. on face the nation, senator cornyn said the intelligence committee hasn't decided whether to grant immunity to general michael flynn, the president's former national security adviser. flynn asked for immunity late last week, and president trump. said he supported that request. >> let's bring in jok dickerson, from face the nation. it is interesting that president trump basically directed flynn to seek immoounlt, how should we

interpret that? >> the president himself with the russian efforts to influence the election. another way to look at this though is in a highly partisan environment where there are two congressional investigations and an fbi investigation that mr. flynn may have exposure in some way based on his other business dealings which we're still learning about after he left the white house and that in order to limit his exposure, his smart lawyer is trying to get a deal, and that it's basically -- has more to do with the exposure that general flynn has than the exciting quality of what he may have to say. >>ninan: i want to turn now to the supreme court, angus king considered the swing vote on neal gorsuch's nomination, what are you watching for as we get closer to a vote this week? >> i think what we're watching for is basically whether the

republicans can get enough senate democrats to avoid having to invoke the nuclear option, changing the senate rules to make it that neal gorsuch would be confirmed with the 60 votes, in craft to the filibuster. this would be a particularly difficulty one, given what the republican leader or what senator kornun said, they said it would hurt the institution so it would be a big deal. and so it looks like that's where we're headed and it's another sign of in a partisan age where we thought we had gotten partisan in every way. >>ninan: john dickerson, thank you. >> thanks reena.

>> a grey, threatening dawn over london and a grey, many say threatening, future for britain. nine months after voting for it the british handed the eu its official demand for divorce. >> this is an historic moment from which there can be no turning back. >> theresa may's government and the eu now have two years to negotiate the terms of the divorce. a negotiation eu president donald tusk said would not lead to a win-win outcome, but to lose-lose. >> this is about damage control. >> a lot of people are already trying to control the damage. at azimo, a currency trading company, they're planning to move part of their operation to ireland to stay in the eu trade zone that brexit will almost certainly take britain out of. and ceo michael kent says not just the little guys are hedging their bets.

>> and let's do it here in st. pete, first pitch is low and inside and we are underway, the season has begun. >>ninan: the first pitch of the 2017 baseball season. this year brings a few new rules - aimed at speeding up the pace of the game. we end tonight with the story of a man and a baseball -- on a unique journey. in 2010, a man named ralph carhart began what he calls "the hall ball" project. the goal: taking a picture of a single baseball - with every member of the hall of fame -- living and deceased. brook silva braga has the story. >> the ball ralph carhart has taken to 33 states isn't much to look at. his wife pulled it out of a creek, near the baseball hall of fame, and ralph got it in his head to take a photo of the ball with every hall of famer. >> i had no concept seven years

ago as to just what this was going to mean, how long it was going to take, how much travel i was going to have to do. >> 37,000 miles so far, by road and air, has yielded these three hundred pictures. yogi berra and reggie jackson.ù cal ripken junior and ozzie smith. most hall of famers are deceased, so carhart drove to idaho to find harmen killibrew's gravesite. babe ruth took him to hawthorne, new york. ted williams's picture: at the cryogenics lab where william's head is preserved. >> not every interaction with the living guys is great. some of them just don't understand why i would do such a thing. >> yeah, the tommy lasord >> (laughing) that phototells it all. but the ones who do get it, wade boggs was another one, who got it, who thought it was really neat. lou brock kept me there for about 10 minutes, i took the first couple of photos and he

didn't like the way he looked so i had to keep taking photos of him until he really liked his hair. >> carhart doesn't ask for autographs, which confuses some players, and sets his project apart. >> there are probably a number of other people out there, in fact i know some, who have tried to get autographs of all the hall of famers but this is a little different. and this sounds like something nobody has ever done before. >> last week, carhart visted hinchliffe stadium in paterson, new jersey, to honor monte irvin-the negro league star who doesn't have a gravesite but played at the field. >> thanks, monte" >> that leaves sixteen more pictures to take. then carhart hopes to return the ball to where he found it. "i wanted to create something that would be in the hall of fame and hopefully they accept the ball when i'm done with the project and i can take my kids there and say, look, dad made that." >> brook silva-braga, for cbs news, paterson, nj.
