WASHINGTON — We may never know whether the government's $700 billion bailout of the financial industry worked, according to a new report from congressional auditors. That's because it will be impossible to sort out which of the government's spending and other tinkering has made a difference, according to the report released Friday by the Government Accountability Office.

"The lack of a clearly articulated vision has complicated Treasury's ability to effectively communicate to Congress, the financial markets, and the public on the benefits of TARP," the report said.
