they say walls don't work. walls work 100%. >> when you're talking drugs maybe not all of it, i think it's only 90%, but that's a lot. how do you respond to that, though? >> the overwhelming amount of drugs come to this country through legal ports of entry. if we're serious about doing something about that, we need to make investments so there are car go investments, additional personnel to prevent the drugs from coming in the country. that's where they come. the president keeps throwing out statements that are not supported by the evidence, not supported by his own department of homeland security or customs and border patrol. i've been to the border twice and they said it used to be single men come, now it's families. we need to respond to that in a humanitarian way but that's the change of circumstance that's happened at the border. there's not an emergency there.
