Total Cost of the Bailout?

I'll just copy and paste this story from Bloomberg, it's short and sweet:

July 20 (Bloomberg) -- U.S. taxpayers may be on the hook for as much as $23.7 trillion to bail out financial companies, according to Neil Barofsky, special inspector general for the Treasury’s Troubled Asset Relief Program.

Barofsky made the estimate in testimony prepared for a congressional hearing tomorrow.
