quickly heating up. op the republican side six people already officially launching campaigns. it is a diverse field, and it appears more candidates are waiting in the wings. among them former florida governor jeb bush who just has given fox news megyn kelly his first sit-down interview in months. more on that in a moment. the three latest candidates gave their lists of reasons why they deserved to be president. doug let's begin with carly fiore iny and dr. ben carson. >> it can be a plus or negative as well to be an unknown. there's a balance to be struck on the other side. a recent poll finds 70% of voters would be uncomfortable electing a president with no political experience. two of the gop candidates to announced this week carly fiorina, and ben carson going for the highest office in the land. >> i've run my own campaign. i've advised others. i've helped lots of others win. in addition i have done a lot of policy work advised secretaries of defense, secretaries of state and homeland security. >> there's real life experience and there's politics. politics politics you know there's some good people in the political arena. but i'm not sure that they actually in many cases understand real life. >> the third gop candidate to announce this week is former arkansas governor mike huckabee. his strong social conservatism appeals to many in the gop base. but he's facing resistance from fiscal hawk. today he appealed to a key constituency seniors, when he defended social security against cuts that some say need to be made to protect its long-term solvency. >> understand the program, has some real fiscal problems. but why would you punish the recipients who play by the rules that they were forced to play by. >> huckabee's chances are seen as slimmer this time around given the array of candidates who have already entered the race. but he could play a spoiler role by taking christian votes away from other gop candidates. >> a new poll from the important caucus state of iowa has now shifted in recent weeks. what are your thoughts? >> according to the new university poll released just on may 6th, wisconsin governor scott walker has a big early lead in the iowa republican caucus but not as big as he had at one time. rand paul marco rubio, ted cruz and mike huckabee are now jockeying for second place with numbers between 13% and 11%. jeb bush with 5%. >> feels like it's heating up. still more people getting in. you're right, it's early. now to former florida governor jeb bush who just sat down as i mentioned earlier with megyn kelly for an exclusive interview. governor bush making news on several issues in that. at one point megyn asked if he would have invaded iraq. >> the subject of iraq obviously very controversial, knowing what you know now, would you have authorized the invasion? >> i would have. and so would have hillary clinton, to remind everybody. and so would almost everybody that had the intelligence that they got. in retrospect the intelligence that the world saw, not just the united states was faulty. and in retrospect once we invaded, and took out saddam hussein, we didn't focus on security first. and the iraqis in this incredibly insecure environment turned on the united states military because there was no security for themselves and their families. guess who thinks that those mistakes took place as well. george w. bush. >> your brother. >> yeah. so just for the news flash to the world, if they're trying to find places where there's big space between and my brother, this might not be one of those. >> we can watch this entire exclusive interview on "the kelly file" with megyn kelly tomorrow in primetime, 9:00 p.m. eastern right here on the fox news channel. we'll have more on mr. bush's insights a little later here on the fox report. new information on a fourth suspect charged in the shooting death of two police officers in mississippi. the victims of former officer of the year and a rookie

guyana where he was going to monitor elections tomorrow. his staff is still there we're told to observe the vote. now let's get back to the story that i was telling you about at the top of the hour the severe weather that's moving across the country. more information coming in and brand-in you pictures. parts of denton in north texas especially hard hit. they're trying to recover in the wake of a destructive twister. and there's massive flooding. here's a look at a water rescue that's going on right now. we switched from the brand-in you video to live pictures. but i want to keep these pictures up for just a second if we can. we're watching these pictures this is denton texas. i want to skip ahead a little bit in your reporting. and get your point of view. because i know you were caught up in one of these storms. tell me what you experienced. >> that's right. it's sunny where we are right now. but there's dangerous weather playing out across this region. a tornado actually touched down in denton a little bit earlier today. and for the past couple of days all across this region it has been raining nonstop. just pounding this area. so a lot of people think that they're safe. what you're watching play out right now in denton is where people think they're okay but within just a matter of seconds, the flash flooding starts because it starts raining so hard and they get caught in a very dangerous situation. and the first responders have to get out there and try to save them as quickly as possible. we've seen this over the past couple of days just so much rain so quickly, it's easy to imagine how this could be playing out in denton right now. >> all right. that perspective is so helpful. i looked down at the associated wires now, and here's what the associated press wires are saying. that this is the town of crumb and that the denton county emergency services chief says that they are in the midst of a helicopter rescue. people caught in the rising floodwaters, will as you described, so detailed just in because you've been through this just recently. i want to move on to the area you are, because you're in cisco. >> reporter: that's right. one thing i'll add real quickly, sometimes people's attention go to the tornado that comes with this weather. but the flooding is just as important to pay attention to on your cell phone. in the last couple of days we've gotten a couple of flash flood advisories. if you get one of those, go home and stay safe if you can. in cisco is a home that destroyed, seven homes were destroyed. one woman passed away. the tornado also killed several cows on her property. the national weather service was out here a little bit earlier today and they determined this was an ef-3 tornado. that means it has sustained winds up to 165 miles per hour. we spoke to rhonda phillips a little bit earlier. she lives pretty close by. the tornado destroyed a barn that was built by previous owners on her property 100 years ago. it destroyed it in just a matter of seconds. >> what they helped build is just gone in a matter of seconds. it's heartbreaking. but we're good. we survived it. we'll clean up. and still make this a place that's pretty one day. >> reporter: one quick story i'll leave you with harris. we were in town getting lunch. a woman walked in she said she wanted to buy sandwiches for five or six men who was on her property. when she got to the cashier, another resident jumped up from his seat and slapped his credit card down and said we've got you. that's the mentality we've seen across the area all day long. >> i want to bring back live pictures if we can. the emergency chief now said they've had to do this multiple times. these helicopter rescues. these are live pictures in the town of crumb. denton county. located about 50 miles northwest of dallas texas. would you look at the water that's pouring in from one side. and inow you've been in this area will. that water is moving with some velocity. you can tell from these pictures. i'm not sure if we still have will. will are you still with us? it sometimes can happen with these situations. we'll lose a live shot a satellite live shot because there's still weather moving into the area. what you're watching right now is the live rescue. we know there's heavy flooding obviously as these tornadoes have ripped through the area. you heard will carr caught up in one last night. he took cover and was safe. what happens is the skies kind of clear up. people hit the roadways and they don't understand that that water can breach the sides of those roadways and create a situation like this. the denton county emergency services say they've now closed many roads, and they're doing high water rescues in north texas, not just the one you see on your screen here. we're going to keep a watch on the situation, and update you as we can. now let's move on to concerns on how to stop the islamic state's terror army from making the
