Former Democratic governor and financial broker Jon Corzine, who oversaw the collapse of major derivatives broker MF Global, says he doesn’t know where the $1.2 billion missing from client accounts has gone. He also says he doesn’t know if it was inappropriately invested.

Corzine, who the Obama Administration relied on for economic advice and who has been a major contributor to Obama’s reelection campaign, is set to testify on Capitol Hill today. He is expected to invoke his Fifth Amendment rights and refuse to answer questions.

“I simply do not know where the money is, or why the accounts have not been reconciled to date,” Corzine’s prepared testimony read. “I do not know which accounts are unreconciled or whether the unreconciled accounts were or were not subject to the segregation rules.”

MF Global was heavily invested in European debt, which — as you can imagine — has some downsides. The firm, which was heavily overleveraged, has been accused of using investor money without permission to invest in projects of its choosing.

Corzine, who was kicked out of the New Jersey governor’s mansion by voters angry about his stewardship of the state, resigned as CEO of MF Global just five days after the firm filed for bankruptcy.
