CHICAGO (WLS) -- More anti-ICE Chicago protests are expected on Thursday, immigration advocates say. Organizers plan to speak and march against President Donald Trump's administration's immigration policies. The demonstrations come as Chicago Mayor Brandon Johnson warns that ICE is planning to increase their operations in the city.

The mayor's chief of staff said federal agents received notice to deploy to five Democrat-led cities, including Chicago — where recent actions have already drawn thousands to the streets in protest.

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.”

According to the sources, the teams will be activated in Seattle, Chicago, Philadelphia, northern Virginia, including Washington, D.C., and New York.

Three Democratic governors are defending their responses to the migrant crisis​ and dispute claims of failing to cooperate with federal authorities, according to remarks prepared for a congressional panel.

Chicago protest against ICE resulted in 17 arrests with 4 facing felony charges, including aggravated battery and property damage. Thousands participated, with one injured by a car driving through the crowd.
