When Vallas left the post to run for governor, Daley chose the relatively obscure Arne Duncan, who later became the U.S. Secretary of Education under Barack Obama, to lead the district. On March 19, 1997, the Chicago City Council adopted the Domestic Partners Ordinance, which made employee benefits available to same-sex partners of City employees. Daley said it was an issue of fairness. The first major public corruption scandal of Daley's tenure as mayor involved the circumstances of the resignation of his City Council floor leader, Alderman Patrick Huels, in October 1997. Daley, Huels, and another close friend Michael Tadin grew up within two blocks on S. Emerald Avenue in Bridgeport. Huels attended De La Salle Institute, the same high school attended by Daley, his father, and Michael Bilandic. Huels worked for the city's Public Works Department as a laborer and tree trimmer, then as an administrative assistant in the Environment Department, and then as a City Council investigator. He answered phones for the 11th Ward Democratic organization, and was its secretary for several years. When Mayor Richard J. Daley died, 11th Ward Alderman Bilandic was named acting mayor, and Huels, then 26, replaced Bilandic as alderman. Huels chaired the Council's Transportation Committee and became Mayor Richard M. Daley's floor leader. In the summer of 2007, in reaction to ongoing indictments and convictions of aldermen, Daley and Huels shepherded a package of ethics reforms through city council. Huels owned a security firm, SDI Security, Inc. along with his wife and his brother, a Chicago police lieutenant. In the mid-1990s, the firm had about 390 full-time employees and was grossing $7 million a year. Huels was president and a director, and Council Finance Committee Chairman Alderman Edward M. Burke (14th) was secretary. Huels and Burke authorized $633,971 in legal consulting fees from their respective Council committees to attorney Michael A. Pedicone, a long-time officer of SDI. In March 1995 the Internal Revenue Service placed a lien on SDI for $326,951 and in June 1996 for $997,382 for failing to pay payroll taxes, including money withheld from its employees' pay checks. In 1970, after high school, Tadin went to work for Marina Cartage; within a decade, he owned the company, and over the next 15 years expanded it from 20 trucks to 150.
