The Republican presidential candidate set himself apart from the billionaire businessman,telling Jake Tapper on CNN’s “State of the Union” that Trump’s plan to round up undocumented immigrants is “not how we enforce the law for any crime.”

“No, I don’t intend to send jack boots to knock on your door and every door in America,” Cruz said. “Door-to-door, we don’t have any system that knocks on the doors of every person in America. That is not actually how the American law enforcement system works. We also don’t have people going door-to-door looking for murderers. We don’t live in a police state.”

Cruz said law enforcement practices currently in place will find undocumented immigrants who are living under the radar.

“Listen, we have an enforcement force. It’s called border patrol and it’s called Immigration and Customs Enforcement,” he said.

Trump in November pledged to authorize a “deportation force” to “humanely” remove millions of undocumented immigrants from the U.S.

“You have millions of people that are waiting in line to come into this country and they’re waiting to come in legally,” Trump said at the time. “And I always say the wall, we’re going to build the wall. It’s going to be a real deal. It’s going to be a real wall.”
