Two major developments in the federal investigation of Chicago's Hired Truck program: 1. State Sen. Antonio Munoz is cooperating with investigators. Munoz, known in court documents as State Senator A, is connected to Angelo Torres, who ran the Hired Truck program, but is apparently not the target of the investigation. 2. Daley scraps Hired Truck program and bans his campaign contributors from doing business with the city. Long overdue, to say the least.
