The eye-popping national debt surpassed $11 trillion Monday, the largest in U.S. history.

The new Treasury Department figures on the national debt were released as the non-partisan Congressional Budget Office is expected to project that the annual budget deficit will be higher than previously estimated by the White House's Office of Management and Budget. The debt, which refers to the cumulative amount of money the government owes, hit $10.9 trillion on Friday.

The whopping number has major ramifications for President Barack Obama, who is trying to push through a raft of big-ticket bills on health care, energy, education and climate change — while also attempting to stabilize the swooning economy.

Sen. Kent Conrad (D-N.D.), chairman of the Budget Committee, said Tuesday that the numbers could force Congress to make "adjustments" to Obama's $3.6 trillion budget plan.

"It’s very important get a result for the American people and one that has the priorities that have been [announced] by the president in terms of reducing our dependence on foreign energy, that’s in all of our interests, excellence in education, health care reform and dramatic reduction of the deficit,” Conrad told reporters. “Those will be our guiding principles as we go forward, but as I say, we’ve not yet seen CBO’s new numbers. But I think we can all anticipate because they were done substantially later than OMB’s, that they are going to be more adverse. That that’s going to require all of us to make adjustments.”
