Protesters by the thousands marched through Chicago on Tuesday, stopping traffic in the downtown Loop and chanting anti-Trump slogans as they denounced immigration raids in Los Angeles, Chicago and other cities.

Protesters against U.S. Immigration and Customs Enforcement fanned across downtown Chicago Tuesday evening, and some police vehicles were vandalized as the marchers passed. Sabrina Franza and Jermont Terry are on the ground.

Chicago is responding to President Donald Trump’s aggressive immigration raids with protests. Here’s what we know with two more planned.

The people of Los Angeles and surrounding areas have taken a courageous stand against Trump’s reign of terror targeting immigrant families,” according to organizers in a social media post about the planned protest.

The effect of the ban was not apparent Monday at O'Hare International Airport where, eight years ago during Trump's first attempt at a travel ban, hundreds protested and over a dozen people were arrested.

HOW WE GOT HERE: The protests erupted after Immigration Customs Enforcement (ICE) officers on Friday carried out raids in three locations across L.A., where dozens of people were taken into custody. Newsom called the raids “chaotic federal sweeps” that aimed to fill an “arbitrary arrest quota.”

Protesters will converge nationwide for "No Kings" protests. But what are they? Why protest on Trump's birthday and military parade? What to know.

CNN’s Rosemary Church asks Pablo Alvarado, the co-executive director of the National Day Laborer Organizing Network who called for peaceful protests to protect vulnerable immigrant communities, what he thinks about the violent protests in Los Angeles.
