Another milestone set by the Obama Administration: The Outstanding Public Debt as of May 25, 2010, has topped $13 trillion for the first time, according to the U.S National Debt Clock.

The estimated population of the United States is 308,438,503 so each citizen's share of this debt is $42,156.59, according to the Web site.

The National Debt has continued to increase an average of $4.12 billion per day since September 28, 2007.

Under Obama, the annual federal budget deficit is more than $1 Trillion a year, so that $13 Trillion will just keep growing.

Heckavu job, Barack.
