The claim

“I think what the president’s talking about is beginning with the dangerous persons that we know are here. There are criminals, known criminals. There are known terrorists in the country. There are some who have been apprehended, apprehended for committing violent crimes after they have come across the border illegally. So, you start with that number, you have got, by some counts, as many as 3 or 4 million people that fit that category.”
