locally transmitted zika viruses that were transformed in florida. thanks for joining us. good night. captioning sponsored by cbs >> pelley: trump goes off script and critics say over the line. >> if she gets to pick her judges, nothing you can do, folks. although, the second amendment people, maybe there is, i don't know. >> pelley: also tonight, more zikaas mosquitos. >> we want to start a family soon, and this may keep us from doing so. >> pelley: new calls for tighter regulation of amusement parks after the tragic death of a young boy. and thousands hike the appalachian trail every year, but not the way stacy kozel is doing it. >> reporter: hang on, hang on. i have never heard that sentence before. >> i know.

>> pelley: the teleprompter was gone today. donald trump spoke off the cuff and took his campaign off the rails, again. this time, it was a remark that some took as a threat of violence against hillary clinton or the supreme court justices she might appoint if elected president. here was trump in north carolina. >> hillary wants to abolish-- amendment. by the way, and if she gets to pick-- ( booing ) if she gets to pick her judges, nothing you can do, folks. although, the second amendment people, maybe there is. i don't know. >> pelley, of course, the second amendment establishes the right to bear arms. the clinton campaign said trump was inciting violence. trump's campaign had another

trump's first impulse was to put out a statement that blamed the "dishonest media." in it, the trump camp felt no need to explain what trump meant and address accusations that even indirectly, he was calling for violence against hillary clinton. however, scott, trump did address this roiling controversy moments ago in an interview with cbs affiliate wncn, here in north carolina. >> reporter: if you could explain what you meant. >> well, i think you're talking about-- i'm not sure us but i think you're talking about the power of people that are in favor of the second amendment, and they have tremendous political power, and i think they really are strong. they're united. >> reporter: even so, comments like this have driven away members of trump's own republican party, among them maine senator susan collins, who wrote this morning in the "washington post" trump's "lack of self-restraint and his barrage of ill-informed comments

world even more so." the national rifle association, which encored trump in may, came to his defense, tweeting that trump is right about the supreme court and in a second tweet, urged voters to defeat clinton with the hashtag #neverhillary. now, scott, senior trump strategist jason miller told me in a phone interview that, of course, trump was not referring to violence, only the political clout wielded by voters who are passionate about the second amendment. rudy giuliani amplified that >> pelley: major, thank you. but, of course, that's not the way the clinton campaign sees it. nancy cordes has that. nancy. >> reporter: scott, clinton campaign said there is no disputing what trump meant, and campaign manager robby mook issued this statement: clinton's running mate, senator tim kaine, just weighed in a

>> reporter: massachusetts senator elizabeth warren followed that up with this: interestingly,co democrats are not expressing tonight is surprise. they note that this is the same man who encouraged violence against protesters at his rallies and who joked that he could shoot someone and still not lose votes. >> pelley: nancy cordes reporting. nancy, thank you very much. clinton opened a rally near orlando yesterday by paying tribute to the 49 people who were murdered in june at the pulse nightclub. well, it turns out just a few

was seddique mateen, the father of the orlando gunman. taed, the clinton campaign said mateen was not invite to the event. the event was open to the public. the divisions in the g.o.p. are playing out tonight in the primary election in wisconsin. paul ryan, the nation's highest ranking elected republican, is being challenged for renomination. here's dean reynolds. >> reporter: paul ryan is the speaker of the hound president. he's been elected nine times to congress and has impeccable conservative credentials. and yet, donald trump did not endorse ryan in today's republican primary until just four days ago. >> i support and endorse our speaker of the house paul ryan. ( cheers ) >> reporter: just as trump was slow to come around to ryan, ryan was slow to come around to trump.

with ryan's long-shot primary challenger, businessman paul nehlen. >> i build things, create jobs. >> reporter: last week when trump thanked nehlen on twitter for "your kind words, very much appreciated," nehlen went from nobody to somebody. >> mr. trump and i are absolutely crisply aligned on being against bad trade deals that paul ryan supports. >> reporter: the race here is symbolic of the larger split in the g.o.p. over trump, whose base of support sees ryan as the establishment they oppose. at the eastern end of ryan's district in kenosha, glen woods is a constituent but no fan. >> paul might as well get a hillary t-shirt when he gives his next speech. >> reporter: to the west in janesville, ryan's home town, cafe owner angela collas says the primary here has been hot. >> it seems kind of crazy, chaotic, out of hand. >> reporter: as for paul nehlen, he says just giving ryan a run is a victory of sorts.

house? i've already won. i really have already won. >> reporter: but when it comes time to count the actual votes here tonight, scott, most of the people we spoke to in this district believed that paul ryan will have nothing to worry about gle dean reynolds for us tonight. dean, thank you. well, today in miami, hillary clinton called on congress to return from its vacation to pass emergency funds to fight zika virus. florida reportedod more people have been infebted with the virus linked to birth defects, and that brings the number infected by mosquitos in the state to 21. david begnaud is in miami. >> reporter: the four new cases are thought to have originated in the same wynwood section of miami. before the announcement, the mayor of miami-dade county, carlos gimenez, suggested zika is under control here. >> with the fact that we've

we have not had one mosquito that we've caught has actually been active with the zika virus. so hopefully this was very, very contained. >> reporter: experts insist that fighting finding an infected mosquito is like looking for a needle in a haystack. every day jews in the wynwood neighborhood are clearing drains, spraying insecticide. >> does the media need to have a 24-hour outpost on our main street? >> reporter: the nio advisory recommending pregnant women avoid the area is starting to backfire on business owners. >> we did 10% of revenue on saturday when you consider a regular saturday. when you consider saturday is 50% of our weekly revenue, that is the impact it is having on us. >> reporter: 35-year-old erica musser and her husband, darrell, are rethinking pregnancy because of the zika threat. >> we're sort of running out of

there have been a lot of discussions around the dinner table about whether to keep trying at this point. this isn't me crunching numbers for my data. this is-- this is our lives and this is our family. here in wynwood, officials say insecticide spraying is working to reduce the population of the mosquito that carries the zika virus. where they used to find about 25 in mosquito traps they're now finding just one. scott, there's going to be more aerial spraying here in wynwood tomorrow morning and agahi weekend. matthew degennaro in that one neighborhood there in miami that has seen zika transmitted locally so far. david, thank you so much. so far, only florida is reporting local transmission of zika, but today, texas confirmed the first death of a newborn from the virus. the mother was infected in el salvador. a chemical called deet is an effective mosquito repellent, but is it safe?

>> reporter: 31-year-old ali simon is 36 weeks pregnant and lives in new jersey. she knows zika has reepped mosquitos in the u.s., but like many pregnant women we've spoken to wonders if it's safe to use insect repellent. >> i don't feel like it's necessary for me to douse myself in chemicals until i know they need to. >> reporter: but the c.d.c. has said there are insebt repellant safe to use for pregnant women and refers them to a list provided by the e.p.a. that examines the health effects of insecticides. >> all of them have been evaluate for their safety. what we found for deet is there is no sensitivity, extra sensitivity for pregnant women or children from their expos to deet. >> reporter: because of ethical consideration, most research has been done on animals. however, one study looked at pregnant women during the second and third trimefter and found using 20% deet daily was safe for both mother and baby.

done and it's found to be safe. >> reporter: she understands some women's fears around using repellents but is confident in the science. >> having been pregnant at one point in time. >> would use a repellent. i know that they're definitely safe for use, as i participated in the reviews of them. >> pelley: so, john, dana doagle says it's safe, but how do you know which one to use? >> reporter: scott, she told me about matching the product to your specific needs. deet-based products come in concentrationses that range from 5% to a higher number doesn't mean a product will work better. it means it will last longer. according to an industry trade group, 5% deet lasts about an hour while 30% deet lasts up to eight hours. there's an interactive e.p.a. wex that can help you sort out your choices. you plug in things like how long you want protect expreks whether it's from mosquitos, ticks, or both and it gives you a list of products to choose from. but remember, scott, it's important to remember whatever repellent you use you've got to
