The No Kings rally in Downtown Chicago was just one of many planned for around the Chicago area and the country.

People gathered in Chicago and the suburbs Saturday for a "No Kings" protest amid ongoing federal immigration enforcement operations in the area.

Speaking at a "No Kings" rally in Washington, D.C., Bill Nye, the former host of "Bill Nye the Science Guy," urged lawmakers to “stop the abuses of this petulant president [Trump] and his circle of sycophants,” declaring, “No thrones, no crowns, no kings."

President Donald Trump said he could legally invoke the Insurrection Act to tackle violent crime in Chicago, saying presidents have used it before.

The U.S. Court of Appeals for the Seventh Circuit's decision upholds a temporary restraining order granted by a federal judge in Chicago.

President Trump has been declaring Chicago "the most dangerous city in the world" for months, but the data doesn't back up those claims, analysts say.
