The Department of Homeland Security has asked Naval Station Great Lakes for "limited support in the form of facilities, infrastructure, and other logistical needs to support DHS operations," said Matt Mogle, spokesperson for the base 35 miles north of Chicago.

Details about the administration's plans for Chicago remain scarce.

Mogle said no decisions have been made on the request, and that the base hasn't received an official request to support a National Guard deployment. The Chicago Sun-Times first reported on the request to the Navy base.

Chicago Mayor Johnson and Illinois Gov. JB Pritzker have fought back, saying crime has fallen in Chicago and that the city doesn't want or need the military's help. They are planning to sue.
