Trump backs ICE raid tactics, says they 'haven't gone far enough'

"Have some of these raids gone too far?" O'Donnell asked.

"You're OK with those tactics?" O'Donnell pressed.

"Yeah, because you have to get the people out. You know, you have to look at the people. Many of them are murderers. Many of them are people that were thrown outta their countries because they were, you know, criminals. Many of them are people from jails and prisons. Many of them are people from frankly mental institutions," he claimed. "I feel badly about that, but they're released from insane asylums. You know why? Because they're killers."

The White House has repeatedly said federal agents are targeting criminal illegal migrants who are the "worst of the worst."

It was filed by a coalition of journalists, media organizations and individual protesters.

Trump told CBS News he believes his immigration mission will be complete once "many" of roughly 25 million people are deported.

"Well, it takes a long time, because, you know, probably I say 25 million people were let into our country. A lotta people say it was 10 million people. But whether it was ten or - I believe I'm much closer to the right number," he said. "Of the 25, many of them should not be here. Many of them."
