The chairman of the company that owns the Sixers is under investigation: The Pennsylvania Gaming Control Board is investigating whether a $15,000 political contribution from Comcast-Spectacor chairman Ed Snider, who is a partner in the Foxwoods Casino planned for Center City, violated the state ban on campaign giving by gambling interests. Snider gave $15,000 on Jan. 15 to Comcast Corp. PAC-USA, a political committee registered with the Pennsylvania Department of State. The 2004 gaming act prohibits any casino principals from contributing ‘to any political party committee or other political committee in this commonwealth.’ In an interview yesterday, Paul Mauro, deputy director of the Gaming Control Board’s Bureau of Investigations and Enforcement, said only: ‘There is an ongoing investigation, and we don’t comment on ongoing investigations.’”
