Maybe Bush could refinance the White House?

BBC:

US Treasury Secretary John Snow has urged Congress to raise the government's debt ceiling, or face a cash crunch in the autumn.
He warned that Washington was on track to breach the current limit of $7.4 trillion in late September.

If the ceiling is not raised, "we can finance government operations no longer than mid-to-late November," he said.

The move is likely to reignite controversy over the US's spiralling budget deficit.

US government expenditure, swollen by the war in Iraq, exceeded revenues by a record $375bn in 2003, and the gap is forecast to rise again to $445bn this year.

Washington's coffers have also been depleted by a round of controversial tax cuts, seen by critics as a boon to the rich.
