And to maintain that peace requires strength. Reporter but how would trump use the beefed up military to fight isis . I know more about isis than the generals do, believe me. Reporter for more than a year, hes said he has a secret plan. There is a method of defeating them quickly and i dont want the enemy to know what im going to do. All i can tell you is that it is a foolproof way of winning. Reporter now, he says the plan is to ask for a plan. Immediately after taking office, i will ask my generals to present to me a plan within 30 days to defeat and destroy isis. Reporter clinton says trump just doesnt know what hes talking about. He says he has a secret plan to defeat isis, but the secret is, he has no plan. Reporter and in a new ad, a proclinton superpac uses trumps own words to portray him as dangerous.

Well, i just dont think she has a president ial look and you need a president ial look. You have to get the job done. I think if she went to mexico, she would have had a total failure. We had a big success. But when you talk about her not looking president ial, are you talking about aesthetics reporter asked about it today in pennsylvania, Chelsea Clinton did not hold back. I would hope that everyone could see that as the sad, misogynistic, sexist rhetoric that i had hoped we moved beyond in the 21st century, certainly in 2016.
