Treasury Secretary Timothy Geithner is scheduled to present his overhaul of the bank bailout plan, a "comprehensive financial plan," on Tuesday. Two concepts, among others, that could be dealt with are a so-called "bad bank," a government/private-sector partnership to buy up toxic assets from struggling financial institutions, and the potential suspension of the mark-to-market rule.

On a larger scale, the Senate is expected to pass an $827 billion stimulus bill, which to this point has been hindered by partisan disagreements, also on Tuesday. Both the next-step bank bailout and the stimulus package have already been delayed from Monday.

Congressional leaders are aiming to have the bill prepared for President Barack Obama to sign before a recess next week.
