WASHINGTON (AP) -- The Obama administration expects the federal deficit over the next decade to be $2 trillion bigger than previously estimated, White House officials said Friday, a setback for a president already facing a Congress and public wary over spending.
The new projection, to be announced on Tuesday, is for a cumulative 2010-2019 deficit of $9 trillion instead of the $7 trillion previously estimated. The new figure reflects slumping revenues from a worse economic picture than was expected earlier this year. The officials spoke only on the condition of anonymity ahead of next week's announcement.

9 trillion in additional debt over 10 years would bring the total debt outstanding to around 20 trillion.

It did make sense to me though.
