This is the cbs evening news with scott pelley. 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 essentially abolish the Second 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 dont know. Pelley, of course, the Second Amendment establishes the right to bear arms. The Clinton Campaign said trump was inciting violence. Trumps campaign had another major. Reporter scott, Donald Trumps 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 youre in about im not sure because i havent heard this question but i think youre 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. Theyre united. Reporter even so, comments like this have driven away members of trumps own republican party, among them maine senator susan collins, who wrote this morning in the Washington Post trumps lack of selfrestraint and his 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 message here in fayetteville moments ago. Pelley major, thank you. But, of course, thats 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 clintons running mate, senator tim kaine, just weighed in a reporter massachusetts senator Elizabeth Warren followed that up with this interestingly, scott, one thing 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.

And yet, donald trump did not endorse ryan in todays 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. Appeared trumps sympathies were with ryans longshot 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 ry personification of the establishment they oppose. At the eastern end of ryans district in kenosha, glen woods is a constituent but no fan. Paul might as well get a hillary tshirt when he gives his next speech. Reporter to the west in janesville, ryans 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 house . Ive 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.

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. Unless a safety evaluation is done and its found to be safe. Reporter she understands some womens 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 theyre definitely safe for use, as i participated in the reviews of them. Pelley so, john, dana doagle says its safe, but how do you know which one to use . Reporter scott, she told me about matching the product to your specific needs. Deetbased products come in a higher number doesnt mean a product will work better. It means it will last longer.
