Neither Chicago Mayor Brandon Johnson nor Illinois Governor JB Pritzker has been accused of criminal wrongdoing, though both have emerged as prominent opponents of Trump's immigration crackdown and deployment of National Guard troops in Democratic-leaning cities.

Trump's call to imprison the two elected officials comes as another high-profile political rival, former FBI Director James Comey, was due to appear in court to face criminal charges that have been widely criticized as flimsy.

Trump has frequently called for jailing his opponents since he first entered politics in 2015, but Comey is the first to face prosecution.

On his social media platform, Trump accused Johnson and Pritzker of failing to protect immigration officers who have been operating in Chicago.

"Chicago Mayor should be in jail for failing to protect Ice Officers! Governor Pritzker also!" Trump wrote, referring to U.S. Immigration and Customs Enforcement personnel.

Johnson signed an executive order on Monday creating an "ICE Free Zone" that prohibits federal immigration agents from using city property in their operations.

"This is not the first time Trump has tried to have a Black man unjustly arrested. I'm not going anywhere," he said on social media.

Pritzker, a potential 2028 Democratic presidential candidate, likewise said he would not back down. "Trump is now calling for the arrest of elected representatives checking his power. What else is left on the path to full-blown authoritarianism?"
Trump has vowed to harness the power of the federal government to target his enemies. Aside from Comey, his Justice Department is investigating several other high-profile critics. All have denied wrongdoing, and Comey is expected to plead not guilty to charges of lying to Congress.
