Denver Mayor Mike Johnston said he would work with the incoming Trump administration on deporting violent criminals, but not all deportations.

CNN’s Erin Burnett speaks with Denver’s Democratic Mayor Mike Johnston about President-elect Donald Trump’s new “border czar” threatening him with arrest if he does not comply with directives to assist in carrying out mass deportations.

Incoming border czar Tom Homan says he is willing to send Denver Mayor Mike Johnston to jail if he follows through with threats to use Denver police to block deportations.

Homan’s comments come after Mayor Mike Johnston said he was willing to go to jail to stop possible mass deportation efforts under the incoming Trump administration.

Tom Homan, the incoming border czar, said Monday that he was willing to put the Denver mayor in jail if he didn't comply with the Trump administration's immigration policies.

"But, look, me and the Denver mayor, we agree on one thing. He’s willing to go to jail, I’m willing to put him in jail."

President-elect Donald Trump’s “border czar,” Tom Homan, said he would jail Denver Mayor Mike Johnston if he stands in the way of the administration’s mass deportation plans. The former Immigration and Customs Enforcement director told Fox News’s Sean Hannity that Johnston’s public defiance of Trump’s proposed immigration policies would be violating federal law.
