Chicago Fraternal Order of Police President John Catanzara has officially retired from the Chicago Police Department. He will continue as head of the police union and says he wants to run for mayor in 2023.

Catanzara turned in his retirement papers Tuesday morning following a disciplinary hearing Monday.

Catanzara, who joined the department in 1995, has been accused of violating several CPD rules with comments that he made on Facebook in the years before he was elected FOP president, WGN reports.

He was also accused of improperly filing complaints against one of his previous supervisors, as well as former CPD Supt. Eddie Johnson over his involvement in a 2018 anti-violence march on the Dan Ryan Expressway.
