Chicago Mayor Brandon Johnson is trying to oust the Chicago Housing Authority Board Chair, Matthew Brewer, after the agency voted in the appointment of Keith Pettigrew as its new CEO. The CHA has been without a CEO for 16 months and Johnson, who pushed for the selection of retired Ald. Walter Burnett, has been criticized for having conflicts of interest with his ownership of properties rented to housing voucher holders. Johnson also removed Brewer from his role as the CHA’s interim operating chairman, but it's unclear if he followed proper procedures to do so. The board’�s bylaws state the board chair is designated by the mayor and a certificate of Appointment with the Recorder of Deeds of Cook County falls under the Cook County Clerk” Office.
