McCain: a border wall won't stop illegal immigration

In an interview with The Arizona Republic Thursday, McCain explained that he's concerned about the Trump administration's approach to immigration reform:

"I'm not against a border wall, OK, but go to China and you'll see a border wall there. We need technology, we need drones, we need surveillance capabilities and we need rapid-reaction capabilities... But to think that a wall is going to stop illegal immigration or drugs is crazy."

McCain also said he supports a merit-based system, but worries about how low-skilled workers, such as those who pick strawberries in fields across America, would survive under the Cotton-Perdue bill that Trump helped introduce Wednesday.

"I think you have to consider that we do want high-tech people, but we also need low-skilled people who will do work that Americans won't do," McCain said. "I wouldn't do it."
