Communities across the Chicago area are preparing for an increase in immigration enforcement on Saturday.

Some 300 federal agents are using North Chicago’s Naval Station Great Lakes as the logistical hub for ramped-up operations, which are expected to begin on Saturday.

President Donald Trump says the surge in immigration enforcement activity in the Chicago area is about getting dangerous criminals off the streets.

Sens. Dick Durbin and Tammy Duckworth, along with Congressman Brad Schneider, went to the Navy directly for answers on Friday.

They say the admiral-in-charge at Naval Station Great Lakes told them that Immigration and Customs Enforcement and Department of Homeland Security officials requested office space and parking at the base from Sept. 5 through Oct. 5.

The Navy agreed, but is not providing barracks or housing, nor are they allowing the federal agents to have lethal munitions on base.

The Illinois representatives say they tried to speak with DHS officials on base, but with no luck.
