"Chicago Transportation Commissioner Miguel d'Escoto came to a City Hall meeting with his resignation letter in hand Thursday, correctly sensing that he would be the next department head to be swept from his job in Mayor Richard Daley's housecleaning. Five other city employees--all Water Management Department workers implicated in an alleged time-sheet scam--also were canned. The announcement was made by Ron Huberman, a former police official named chief of staff by Daley last month with orders to clean up City Hall in the midst of a string of scandals. D'Escoto's departure was rumored for weeks. The Transportation Department has figured prominently in the federal investigation into the Hired Truck Program."
