Be interested if you have a source for the $800 Billion number. I thought it was quite a bit...50% more - around 1.2 Trillion.
Maybe it's just me, but these days anything less than a Trillion seems almost....well, trivial. It's the Obama effect.
Here’s the link...I looked it up a couple of days ago.

Treasury actually shows it at 727 billion.
