royce of walls is wired so when people try to break through it. then he asked the army corps of engineers head lieutenant general todd a little bit how that works. sir he said there could be merit in not discussing that in other words, we are not going to tell people how we will know trying to break through the fence. ainsley: a lot of people have asked especially the democrats i thought you said mexico was going to pay for the wall. i could easily slap a 5% tariff on automobiles and other goods coming into the u.s. i don't want to do that right now because mexico is so helpful. they have brought out 27,000 soldiers on the border to try to prevent people from coming in our country. they have broken up the drug cartels. he doesn't want to make them mad by slapping tariffs they have been so helpful unlike congress who needs to close loopholes. brian: the president says he wants 400 miles before election day. we will see how that goes. north of the border. they are having an election. liberal justin trudeau
