Former ICE Director Thomas Homan says walls work

"Every place we've built a wall -- San Diego, Yuma, El Paso -- the results have been a decrease in illegal immigration, a decrease in drug supply," he said on Fox News.

"The data is there. I keep hearing Democrats say, 'The wall doesn't work.' Then you're ignoring the data. Every place that it's been put up, it's worked 100 percent of the time. So if it works, what price are you willing to put on our national security and public safety?"
