David Rubin gave $40,000 to Rendell's campaign committees between 2001 and 2005. His Beverly Hills, Calif.-based company, CDR Financial Products Inc., also continues to hold a $45,000-a-year contract as an adviser to the Pennsylvania Housing Finance Authority.
A federal grand jury is probing state contracts in New Mexico to see whether they are related to $100,000 Rubin and his company gave to Richardson in 2003 and 2004.
Rendell spokesman Chuck Ardo says questions about the contributions to the governor are "much ado about nothing."
