0 happening right now, deadly storms savaging the country from the southeast to the midwest, bringing torrential rain, and tornadoes. we are live on the ground in mississippi. developing this morning, a package containing an explosive device sent to arizona sheriff joe arpaio. we're gearing details on that. and a brawl that clears the benches. it could cost one team a big money player for a long, long time. it is friday, april 12th. "starting point" begins right now. breaking news this morning. secretary of state john kerry with strong words for north korea. >> kerry touching down in seoul overnight for talks with south korean leaders. in a news conference just about an hour ago, he stressed this, north korea will never be accepted as a nuclear power. the only way there will be talks between our countries is if north korea is serious about denuclearization and china can play a role in this pivotal crisis. >> neither the united states nor the republican of korea nor the international community, we are all unite d in the fact that north korea will not be accepted as a nuclear power. >> jim clancy live from seoul for us this morning. he said the united states will defend its friends and allies in the region, and at listening to the beginning of those remarks, he did not mention the north korean leader's name. >> no. he referred to him -- he said, first, you know, the leadership there, particularly one leader, they have a choice here. they have to make the right decision. clearly, what secretary kerry was trying to do here was seize the initiative. using diplomacy, yes. but laying it out straight, just as you've described there, notifying the north its nuclear program was absolutely unacceptable. and in talking about that, as you say, he mentioned that the u.s. was firm with south korea, that it had deterrents in place. listen. >> the rhetoric that we're hearing from north korea is simply unacceptable by any standards. and i am here to make it clear today on behalf of president obama and the citizens of the united states, and our bilateral security agreement that the united states will, if needed, defend our allies and defend ourselves. >> well, there was still -- there was still some carrot there, though, for north korea. secretary kerry had this to say. u.s. president barack obama has ordered that a number of exercises, meaning part of that joint u.s./south korean military exercises under way, will not be undertaken. he says i think we've lowered our rhetoric significantly attempting to find a way for reasonableness to prevail here. now china had mentioned that was one way for the u.s. to step back a little bit, create some room for kim jong-un to step back, as well. it seems that even before he's arrived in beijing, the secretary has made good on that pledge to china. back to you. >> all right, jim clancy for us in seoul this morning. thanks, jim. new this morning, developments from the pentagon over that surprising intelligence assessment of north korea's potential nuclear capabilities. our pentagon correspondent chris lawrence joins us and chris, it really seems like the obama administration is attempting to do some damage control over a surprising release of sensitive information. >> john, the assessment that was released was only one line. and that's all we reported, one line. the amount of clarifications and denials we've been getting from u.s. officials, number paragraphs. the latest coming just this morning from a u.s. official who is traveling in korea, who says he does not believe that north korea has put all the components together to be able to put a nuclear warhead on a missile and fire it and accurately aim it. this comes after late last night the director of national intelligence said, look, this assessment is just one military assessment. it doesn't mean that other intelligence agencies like the cia have come to the same conclusion. bottom line, what we know from the assessment says that it believes that north korea has nuclear weapons that would be able to be put on a ballistic missile. officials have since come back and clarified saying basically they don't think the north has been able to miniaturize, to the point where they could take a warhead, marry it to a missile, actually launch it, and actually hit something that they were aiming at. and the report does caveat and say, look, reliability will be an issue. and that's something north korea has had issues with before. being able to say, when they actually push that button, that missile will actually fire, and they can actually hit what they're aiming at. john? >> the big question, chris, would they actually work? right now the intelligence community saying probably not, it seems. chris lawrence, thanks so much. >> in just a few minutes, california republican congressman buck mckeon, chairman of the armed services committee, is going to join us live and talk to him about today's developments. also happening right now, tornado watches have been extended for north carolina and virginia after a series of devastating twisters. also due to relentless storms ripped a path of destruction from texas all the way to the dakotas. cars were tossed around like toys. homes destroyed. and entire neighborhoods you can see, just strewn with debris. at least one person was killed and five more injured as this violent twister ripped through mississippi. kemper county bohr the brunt of this storm. david mattingly is there live with the latest. good morning, david. >> good morning, john. this storm was deadly. but it was also massive leaving behind scenes of destruction just like you see behind me for hundreds of miles. >> it was probably the worst damage. >> reporter: for the second straight day, severe weather, menacing more than a half dozen states. the hardest hit, mississippi. this tornado caught on video. in one county, one person was killed. five were injured. in one rural area, there was a path of destruction at least 30 miles long, extending into west alabama. >> as i was cleaning up the spot where i'm fixing to put another mobile home and i went home to take me a quick bath and i heard the siren going off. that's when i jumped in my clothes and i come on out the house quickly. >> reporter: the storm system swept across the southeast. knocking out power to thousands. toppling trees and damaging homes. into the night, watches and warnings, storm damage, all the way into georgia. >> i've lived up here about two years. about the third or fourth one that's come through this area. so we just seem to be in a topographical situation where the storms come right through here. it's very, very powerful. this one is pretty impressive the way it threw the metal around in the trees. >> reporter: the southeast, accustomed to severe storms, is emerging from a colder than normal spring. these storms, a sign that the season is heating up fast. typically in the month of march we'll see about 100 tornadoes across the country. this year, because of the colder temperatures, we saw less than 20. so now, for the month of april, it is now definitely roaring in like a lion. john?
