From Seattle and Austin to Chicago and Washington, D.C., marchers have chanted slogans, carried signs against ICE and snarled traffic through downtown avenues and outside federal offices.

6:30 p.m.: More than 100 people gathered at the immigration services building and detention center in downtown Los Angeles to protest the raids. DHS officers fired pepper balls at the protesters before the Los Angeles Police Department dispersed the crowd.

Immigration protests across the country and the Trump administration's response to the Los Angeles immigration protests has become a major focus of the New York City mayoral campaign.
