>> reporter: the answer to that question if this discipline that people like can the new overcome the questions he hases raised about his temperament, the second question is does he want to turn the ship around? does he have the inclination and does he have the steering wheel this his hand to actually turn it around? the question is not are we past the time but does he want to turn it around. >> rose: when you talk to people at the state level what, do they say? >> reporter: i dialed around today and first there was a lot of gallows humor. "cass of chaos "is a word t and they worry about if this is lake of discipline in the candidate nape worry about the discipline to do the hard business and the hand-to-hand fighting needed to win in 15 battleground state. the clock is ticking. voting in ohio begins basically in two months. >> rose: thank you, john. while campaigning in florida today, trump attempted to capitalize on a report that the obama administration sent $400 million in cash to iran in january. the timing of that transaction here's margaret brennan. >> reporter: donald trump joined republican leaders in accusing president obama of paying ransom money to iran. >> we paid $400 million for the hostages, right. such a bad precedent, such an unbelievably bad precedent by-- set by obama. >> reporter: the u.s. transferred $400 million to iran last january around the same time that iran freed four american journalist jason rezain. according to the "wall street journal," a cargo plane landed in tehran loaded with stacks of cash, including uros and swiss francs. u.s. sanctions forbid using american dollars in any transactions with iran considered the world's largest state sponsor of terrorism. >> that's false. >> reporter: today the white house spokesman adamantly denied that the $400 million was ransom money. >> no, it was not. it is against the policy of the >> reporter: administration officials say they were simply returning money that had been tied up in a 35-year dispute which the president addressed earlier this year. >> iran will be returned its own funds, including appropriate interest, but much less than the amount iran sought. >> reporter: charlie, republican skeptics charge that despite all the diplomat breakthroughs, iran is still in the00-taking business and point out they are still holding four u.s. residents >> rose: thanks, margaret. tonight, there is more troubling news about zika. 33 members of the u.s. military are believed to have contracted the virus overseas. one of them is pregnant. 15 people in south florida were infected, apparently through mosquito bites. david begnaud reports the state is now at war with mosquitos. >> reporter: before dawn this morning, the plane used for aerial mosquito spraying was grounded in miami due to weather, another attempt will be health officials say targeting breeding grounds is key to reducing the mosquito population. today, workers in miami-dade county inspected 38 homes. five had larvae on the property. >> this is just the preventive measures. >> reporter: in the wynwood neighborhood of miami, police were handing out zika flyers. today, mime's mairk tomas regalado, walked the streets proclaiming it was safe, despite a c.d.c. travel advisory recommending pregn w zika zone. you think it's safe for pregnant women to come here? >> i think it's safe now because i don't think there is mosquitos here. >> this is an urgent need. >> reporter: the mayor said he has spoken with florida's governor rick scott about the travel advisory. did the governor convey whether he wants the travel advisory for this area? >> he does not want the travel advisory. he thinks that that's unfair. >> reporter: based on what the mayor said, we called the governor's office, but they would not respond directly to pregnant women can get a zika test for free. all they have to do is go to a county health department anywhere in state. >> rose: thanks, david. today, the obama administration sent an urgent letter to congress, warning that unless there is quick action, funding for the fight against zika will run out in a few weeks. the n.i.h. has just begun a new vaccine trial and dr. jon lapook is here with more about that. jon, tell us exactly what this trial will this vaccine works it will be a very big deal. yesterday the first of 80 healthy volunteers got vaccinated. now they're between the ages of 18 and 35, men and women, not pregnant but they're at an age where they can be thinking about it. and the main idea will be to test the vaccine for safety and see if it can prime the poddy to fight zika virus. >> rose: when will it be ready. >> reporter: dr. tony fauci unless there is new funding from congress, which hasn't happened so far, the vaccine trial will run out of money and they will not be able to proceed to the next phase. >> rose: if the vaccine is successful, it will end zika? >> reporter: well, an ounce of prevention is worth a pound of cure. imagine what it would mean for all the women around the world in area where's there is active zika and think about what an effective and safe vaccine will mean in terms of stopping the spread of zika but also peace of zika on our web site. cbsnews.c. terrorism is not suspected, but we don't know yet what caused a crash landing today in dubai. an emraits airline jet burst into flames. but everyone got out alive. elizabeth palmer is following this. >> reporter: skidding down the runwayots belly, the first video minutes late, it exploded. just before that explosion, smartphone video inside the cabin shows alarm but no panic. some people even take town their suitcases. but 60 seconds later, the cabin crew is sounding desperate.
