Mark Knoller has the story here:
"The National Debt has now increased more during President Obama's three years and two months in office than it did during 8 years of the George W. Bush presidency.
The Debt rose $4.899 trillion during the two terms of the Bush presidency. It has now gone up $4.939 trillion since President Obama took office.
The latest posting from the Bureau of Public Debt at the Treasury Department shows the National Debt now stands at $15.566 trillion. It was $10.626 trillion on President Bush's last day in office, which coincided with President Obama's first day.
The National Debt also now exceeds 100% of the nation's Gross Domestic Product, the total value of goods and services."
