Rubio: When I'm president, criminal illegals and illegals who haven't been here long will be deported

“If you’re a criminal alien, no, you can’t stay. If you’re someone that hasn’t been here for a very long time, you can’t stay,” Rubio responded.

“Define ‘criminal alien,'” followed up Chuck Todd.

“A felon. Other than immigration laws. But I’ve said that before. A crime, non-immigration related. I don’t think you’re gonna round up and deport 12 million people.”
