CHICAGO (AP) — Federal officials have begun their civil rights probe into the Chicago Police department, and today they plan to speak with Mayor Rahm Emanuel.

U.S. Attorney General Loretta Lynch announced the investigation Dec. 7, as crowds protested the death of 17-year-old Laquan McDonald, who was shot 16 times by a police officer.

Twenty-two other police departments have been investigated since the start of the Obama administration, including Baltimore and New Orleans.
