Based on statements from Sen. Inouye's office and the FDIC, and ignoring speculation from the blogosphere, the entire "conversation" went something like this:

BEEP You have reached the Federal Deposit Insurance Corporation. We are now closed. Please leave a message. "This is Van Luong from Senator Inouye's office. Have you received Central Pacific Bank's request for TARP assistance?"

...a few days pass... "Mr. Luong, this is Alice Goodman, head of the the FDIC's office of legislative affairs. The application from Central Pacific Bank is still under process."

Anything more would be even more speculative.

Yeah - Inouye and his wife have investments in that bank. They were reported to be in the $350,000-$700,000 in 2007, and that represented the majority of his financial holdings at that time. Since then, the value of the bank's stock has decreased by 79%. I'd guess that would put him comfortably in the topmost echelon of wealthy Senators.
