( CNN ) -- Sen. Rand Paul , the son of libertarian-leaning Republican Ron Paul , threw some red meat to the Republican National Convention crowd Wednesday night by counting up the increase in the debt under the Obama administration . `` President Obama 's administration will add nearly $ 6 trillion to our national debt in just one term , '' said Paul , whom Kentucky voters sent to the U.S. Senate in 2010 . The facts : . The national debt -- the cumulative tab run up by the U.S. government over its lifetime -- stood at $ 10.6 trillion when Barack Obama took office in January 2009 . It 's currently running at nearly $ 16 trillion , according to the Treasury Department . The Congressional Budget Office estimates project another $ 600 billion budget shortfall for the 2013 fiscal year . That would make a $ 6 trillion increase in a single term , as Paul says . Fact Check : Paul Ryan misleads on debt panel 's spending cut . But there are some catches . First off , Obama governed for much of the first nine months of his administration under the last budget of the Bush administration . But he did push an $ 800 billion-plus economic stimulus program through Congress early in his term , some of which was spent before that budget year ended in October . Bush 's original budget proposal predicted a $ 407 billion deficit for 2009 , but the final figure was $ 1.4 trillion , according to White House figures . Spending has gone up under the Obama administration : For the 2011 fiscal year , the second full budget of Obama 's term , the federal government spent about $ 3.6 trillion , according to the White House budget office . That 's about $ 600 million more than in 2008 , the last full year under the Bush administration . But the budget gap has another element : Tax revenues have dropped during the 2007-2009 recession and remain lower than before . In the 2007 budget year , which ended shortly before the recession began , the federal government brought in nearly $ 2.6 trillion ; that number fell to $ 2.1 trillion in 2009 and is projected to total $ 2.4 trillion by the time this budget year ends in September . The verdict : . True , but incomplete . While budget shortfalls have added $ 6 trillion to the national debt since January 2009 , some of that spending was already in the pipeline , and some of it is the result of the economic slump that has cut into tax receipts .
