The Bush administration asked Congress on Saturday for the power to buy $700 billion in toxic assets clogging the financial system and threatening the economy as negotiations began on the largest bailout since the Great Depression.

The rescue plan would give Washington broad authority to purchase bad mortgage-related assets from U.S. financial institutions for the next two years. It does not specify which institutions qualify or what, if anything, the government would get in return for the unprecedented infusion.

Congressional aides and administration officials are working through the weekend to fill in the details of the proposal. The White House hoped for a deal with Congress by the time markets opened Monday; top lawmakers say they would push to enact the plan as early as the coming week.

“We’re going to work with Congress to get a bill done quickly,” President Bush said at the White House. Without discussing specifics, he said, “This is a big package because it was a big problem.”

The proposal is a mere three pages long, but it gives sweeping powers to the government to dispense gigantic sums of taxpayer dollars in a program that would be sheltered from court review.

The proposal would raise the statutory limit on the national debt from $10.6 trillion to $11.3 trillion to make room for the massive rescue.
