Illinois Gov. JB Pritzker, who is widely seen as a potential 2028 Democratic presidential contender, on Thursday flipped a personal jab from Donald Trump right back at the president ― and suggested why he was the target of Trump’s vitriol in the first place.

Trump, during a recent speech, mocked Pritzker’s appearance, saying: “He’s too busy eating, he wants to eat all the time.” Trump also imagined the governor ordering five burgers.

Appearing on “Jimmy Kimmel Live,” Pritzker brushed off the insult.

“He loves to make fun of people any way he can,” he said of Trump. “Frankly, that’s how you know he’s afraid of you.”

Kimmel agreed and joked that Pritzker should brace himself for a mean nickname from Trump. He preemptively suggested options like “JBLT,” “JB the Hut,” “JB Pritz His Pants,” and “JBackribs.”

Pritzker, the billionaire heir to the Hyatt hotel fortune, laughed along and offered some of his own nicknames that Trump could use: “Jay Burger” and his personal favorite, “J. Beefy.”

The interview also focused on Pritzker’s fiery speech in New Hampshire on Sunday, where the Democratic governor called for what he described as “mass protests” in response to Trump’s agenda.

“It’s time to fight everywhere and all at once,” Pritzker said during the speech. “Never before in my life have I called for mass protests, for mobilization, for disruption. But I am now. These Republicans cannot know a moment of peace. They must understand that we will fight their cruelty with every megaphone and microphone that we have.”

Pressed by Kimmel on what he meant, Pritzker didn’t hold back.

“I think everybody understands that at this point we’ve got an authoritarian in office,” he said of Trump. “He’s essentially tearing apart the things that really matter to working families across the United States — and nobody’s stopping him.”

Pritzker blamed GOP lawmakers for enabling Trump’s agenda.

“Congress is under the control of his party. They’re all paying homage to him at all times. No one’s willing to break with him,” he said. “The only thing in my view that we really can do on a national level is let them know of our displeasure.”
