Then you weren't paying attention. From last night's transcript:
DAVID MUIR: Let me continue on immigration. It was what you wanted to talk about earlier. So let's get back to your deportation proposal that the vice president has reacted to as well. President Trump, you called this the largest domestic deportation operation in the history of our country. You say you would use the National Guard. You say if things get out of control you'd have no problem using the U.S. military.
FORMER PRESIDENT DONALD TRUMP: With local police.
DAVID MUIR: You also said you would use local police. How would you deport 11 million undocumented immigrants? I know you believe that number is much higher. Take us through this. What does this look like? Will authorities be going door to door in this country?
FORMER PRESIDENT DONALD TRUMP: Yeah.

Are you okay with that? You don't mind national guard troops and police searching through your home and everyone else's? Does the 4th Amendment mean anything to you?
