It’s going to be a long day for former New Jersey governor Jon Corzine. Corzine is expected to testify before a congressional committee today and admit that he has no idea what happened to millions of investment dollars tied to MF Global’s bankruptcy. The missing money came under Corzine’s watch, and he’s expected to deliver a 21-page statement to the committee when he testifies today. Corzine is expected to say he doesn’t know where the money went and why the accounts have not been reconciled.
