Americans protesting Department of Homeland Security actions in Chicago were detained on Wednesday, accused of violence toward agents.

Its agents are immigration officers, like officials at Immigration and Customs Enforcement, or ICE, which is also part of the Department of Homeland Security. While ICE has traditionally operated in the country, Border Patrol’s focus is the 6,000 miles of international border and a zone of about 100 miles inland.

The heavily armed agents carrying out President Donald Trump’s aggressive immigration enforcement push in Chicago are often masked. The man leading them is not.

Federal agents detained at least seven people — including two U.S. citizens — and pepper-sprayed a man Wednesday near the border of Little Village and suburban Cicero, officials said.

Officials say Border Patrol's operations in the Northern California area could start as early as later this week, but that the timing could shift.

U.S. Border Patrol agents deployed to Chicago led a late-night raid on an apartment building this week, rappelling from helicopters onto rooftops and breaking down doors in an operation authorities said targeted gang members but which swept up U.

Venezuelan nationals Yonder Enrique Tenefe-Perez and Luis Gerardo Pirela-Ramirez, who are in the US illegally, were identified as the suspects accused of ramming into a Border Patrol SUV.

Several rideshare drivers were arrested by immigration agents on Saturday at the O'Hare International Airport rideshare parking lot.
