Mayor Rahm Emanuel said at a press conference he formally asked Police Supt. Garry McCarthy to resign on Tuesday morning. 

"I'm grateful for his service to the city," said Emanuel.

This comes in the wake of growing criticism of the Police Department’s handling of the fatal shooting of Laquan McDonald by a white police officer.

Emanuel, also, announced he created a task force to look into the Chicago Police Department. The task force is made up of members that have investigated police misconduct. 

"These problems are real and systemic," said Emanuel.
