Corzine, who resigned as chief of MF Global days after the firm filed for bankruptcy on October 31, has been a prominent fundraiser and personal contributor to Democrats.

He personally donated $69,300 to Democratic causes this year alone, including $15,000 to the Democratic Congressional Campaign Committee, according to data from the Center for Responsive Politics.

Corzine – a former U.S. senator, New Jersey governor, and Goldman Sachs Group Inc chief executive – has been under the gun since revelations the firm bet $6.3 billion on European sovereign debt spooked investors and pushed the firm into bankruptcy.

An ensuing search for hundreds of millions of dollars in customer funds attracted the attention of the FBI, federal prosecutors and lawmakers seeking answers for jilted farmers.
