U.S. President Donald Trump speaks, as he and Apple CEO Tim Cook

Just hours after President Donald Trump called for him to be jailed, Illinois Governor JB Pritzker fired back — taunting, daring, and challenging the President in a striking rebuke.

Asked on camera to respond to President Trump’s remarks, Governor Pritzker said, “Well, let’s start with the idea that this is a convicted felon — I mean, think about that — who’s threatening to jail me.”

“I gotta say, this guy’s unhinged,” Pritzker said of the President.

“He’s insecure, he’s a wannabe dictator, and there’s one thing I really want to say to Donald Trump,” the governor continued, before looking directly into the camera.

“If you come for my people, you come through me. So come and get me.”

When asked what he meant, Pritzker replied: “You know as well as I do.”

The governor also told MSNBC’s Jacob Soboroff that Trump “said he was going after the worst of the worst. It’s not going after the worst of the worst when you’re just literally stopping children who happen to be brown and asking them for papers as if they’re gonna have proof that they’re a U.S. citizen.”

“We want everybody to pull out your phones,” he added, “and film everything you see.”

Earlier on Wednesday, Governor Pritzker vowed to “not back down,” and warned that “Trump is now calling for the arrest of elected representatives checking his power. What else is left on the path to full-blown authoritarianism?”
