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.

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.

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.
