The agents encountered protesters chanting, “ICE go home,” at times.

A Border Patrol boat was seen in the Chicago River around 2 p.m.

Whether agents have made any arrests in the downtown area on Sunday was not immediately clear.

Meanwhile, Broadview Police Chief Thomas Mills issued a statement on Sunday, saying his department is investigating accusations that an Immigration and Customs Enforcement agent attacked a CBS Chicago reporter.

“The Village of Broadview Police Department has launched a criminal investigation into an allegedly unprovoked attack on a CBS Chicago TV news reporter’s vehicle by a chemical munition fired from the direction of U.S. Immigration Customs and Enforcement detention facility. The victim declined medical attention. The Broadview Police Department expects the full cooperation by the U.S. Department of Homeland Security into our criminal investigation,” Mills said.

Protesters rally against immigration enforcement

The Indivisible Chicago Alliance, a grassroots organization dedicated to fighting the Trump administration’s policies and actions in Chicago and beyond, organized events in the city on Sunday.

Even before Sunday’s show of force downtown, dozens of people came out across the city’s North and Northwest sides for what is being called a day of action.

“We think it’s important that we show the majority of us are opposed to what trump is doing. We’re opposed to ICE. We’re opposed to the militarization of our cities,” said protester Geri Kahn.

Protesters, many of them members of Indivisible Chicago, fanned out from Irving Park and Lake Shore Drive in Buena Park to Welles Park in North Center, taking heart from the support of passing motorists.

“We want to make a big statement that the American people, the majority of the American people, are not with the Trump administration,” said protester John Bachtell.

In Humboldt Park, people also came out, but there, their purpose was different. Their eyes were firmly focused on getting people to the ballot box.

“Our actions for today are writing postcards to voters in Virginia to remind them to get out and vote because they have a really important Supreme Court election coming up,” said Kristen Vandawalker with Indivisible Chicago Northwest.

It is an effort to encourage political action from those who might feel their impact, in what is already a blue state, is limited.

sometimes people feel like they can only take so much action or have so much impact within the state so it’s good to have, hey there is something really important happening in Pennsylvania we can help with or Virginia or whatever,” said Jessica Jorsch with Indivisible Chicago Northwest.

Sunday’s actions are all a prelude to what is expected to be a large-scale No Kings protest coming up three weeks from now on Saturday, Oct. 18 in Grant Park.
