Democrat Denver Mayor Mike Johnston recently said he was prepared to break with President-elect Donald Trump’s deportation plans and Republicans are warning he will absolutely suffer the consequences.

Johnston said during a recent interview that he was prepared to protest against anything he believes is “illegal or immoral or un-American” in the city – including the use of military force.

During a Sunday morning interview on Face The Nation, Paul told anchor Margaret Brennan that Johnston’s plan is a “form of insurrection” that could see him removed from office.

BRENNAN: The stated Trump plan is to use the military or military assets, deputize the National Guard, and have them act as immigration agents. Do you believe that is lawful?

PAUL: You know, I’m 100% supportive of going after the 15,000 murderers, the 13,000 sexual assault perpetrators, rapist, all of these people. Let’s send them on their way to prison or back home to another prison. So I would say all points bulletin all in. But you don’t do it with the army because it’s illegal. And we’ve we’ve had a distrust of putting the army into our streets because the police have a difficult job. But the police understand the Fourth Amendment. They have to go to judges. They have to get warrants. It has to be specific. And so I’m for removing these people. But I would do it through the normal process of domestic policing.

Now, I would say that the mayor of Denver, if he’s going to resist federal law, which there’s a long standing, standing history of the supremacy of federal law, he’s going to resist that. It will go all the way to the Supreme Court. And I would suspect that he would be removed from office. I don’t know whether or not that would be a criminal prosecution for someone resisting federal law. But he will lose. And people need to realize that what he is offering is a form of insurrection where the states resist the federal government. Most people objected to that and rejected that long ago. So I think the mayor of Denver is on the wrong side of history and really, I think will face legal ramifications if he doesn’t obey the federal law.

The president-elect’s pick to be the next border czar responded that he’s willing to put the Denver Mayor in jail for outright flouting Trump’s policies.

“You are absolutely breaking the law,” Tom Homan, Trump’s “border czar” designate, told Fox News’ Sean Hannity. “All he has to do is look at Arizona v. U.S. and he would see he’s breaking the law. 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.”

Homan pointed to a statute that says it’s a “felony if you knowingly harbor and conceal an illegal alien from immigration authorities.”

Homan said they have to secure this country and save lives. 

“President Trump has been clear, we want to concentrate on public safety threats and national security threats. I find it hard to believe that any governor would say they don’t want public safety threats removed from their neighborhoods,” he said.
