Former ambassador Dan Rooney returns as Pittsburgh Steelers chairman Pittsburgh Steelers owner Dan Rooney and Steelers president Art Rooney greet EMS worker Kathy Nogalo of Lanoka Harbor, New Jersey before the New York Giants play the Pittsburgh Steelers in week 9 of the NFL season at MetLife Stadium in East Rutherford, New Jersey on November 4, 2012. The game comes just 5 days after Hurricane Sandy strikes the north east section of the United States. UPI /John Angelillo ARLINGTON, Texas, Dec. 17 (UPI) -- Dan Rooney said he is returning as chairman of the Pittsburgh Steelers, after resigning as U.S. ambassador to Ireland. "I want to be involved with the team and the organization in any way I can," Rooney, 80, said Sunday before the Steelers' game against the Dallas Cowboys in Arlington, Texas. I would want to become involved again in league matters where I can be helpful. Rooney, a member of the Pro Football Hall of Fame, resigned from the ambassadorship Friday after serving one term since 2009, a typical procedure in U.S. State Department posts involving non-career employees, the Pittsburgh Tribune-Review reported Monday. The Steelers listed him as "chairman emeritus" in his absence, the Pittsburgh Post-Gazette said. His son Art Rooney is the Steelers' president.
