If “unprepared” Chicago Mayor Lori Lightfoot can’t get crime under control, the feds must be called in to help, a Windy City politician is urging in the aftermath of a chaotic night of riots and looting.

Brian Hopkins, an alderman who represents parts of the downtown area, blasted Lightfoot in a statement to CWBChicago Monday night.

“Our city was devastated by widespread looting and rioting for which our mayor seemed totally unprepared,” he said.

He also accused Lightfoot of offering “nothing but rhetoric and blame,” just like she did after similar riots in May.

He demanded she come up with a “safety plan that will protect all neighborhoods and small business owners.”

Anything short of that and “I am strongly in favor of asking for federal assistance,” Hopkins said.

“Our city cannot afford even one more night of rampant and uncontrolled criminal activity,” he said. “This has to stop. And it has to stop now.”

Earlier Monday, Lightfoot slapped down calls for federal intervention and instead called on the community to come together to prevent future riots.

“Again, no, we do not need federal troops in Chicago, period, full stop,” Lightfoot said.

Chicago’s Magnificent Mile and other parts of the city descended into pandemonium Sunday night into Monday after police shot and injured a 20-year-old man who had fired at them.

That kicked off hours of looting and vandalism that resulted in the arrests of 100 people. Thirteen cops were injured.

Police Superintendent David Brown and Lightfoot said the mayhem was not part of an organized protest.

“This was an incident of pure criminality,” Brown said.
