A man arrested for impersonating a police officer during an anti-ICE protest in Chicago had a loaded semi-automatic weapon, badges and fake documents, police sources said.

The Chicago No Kings rally comes as protests have ramped up against ICE and the Trump administration this week locally and in Los Angeles, where the National Guard and Marines have been deployed against the wishes of local leaders.

Protesters are expected to gather in the Chicago area and the suburbs as part of a nationwide movement called "No Kings."

The woman was taken to Northwestern Memorial Hospital where she was treated and released, Chicago police said.

Chicago Mayor Brandon Johnson encouraged his city to protest the Trump administration’s immigration raids across the country. “I am counting on all of Chicago to resist in this moment,” said Johnson, who is a Democrat. “Whatever particular vulnerable group is being targeted today, another group will be next.”
