Where is GM's burden of proof?

As Kentucky Gov. Steve Beshear is cajoling Congress to write blank taxpayer checks to the auto industry, troubling questions mount about how good an idea that is.

The Wall Street Journal reports:

""There is no Plan B being discussed beyond a government bailout," one top GM adviser said Friday."

Granted, that is a statement from an anonymous source, but I haven't seen anything that leads me to believe GM does have a Plan B. They should have to explain all their contingency plans to us.
