Congressional leaders are trying to come up with enough changes in the administration's $700 billion financial rescue plan to persuade members who voted against it to change their minds and sign on.

Congressional leaders need to attract about a dozen votes to avoid another defeat. Senate Republican Leader Mitch McConnell says it's time lawmakers "act like grownups" and "get this done for all of the people."

Both John McCain and Barack Obama are suggesting adding an increase in the federal deposit insurance limit to $250,000 as a way of boosting confidence in the banking system. Republican House aides say that might appeal to some conservatives who want to help small business owners and avoid runs on banks.

Another possible change would modify accounting rules that require banks and other financial institutions to adjust the value of their assets to reflect current market prices even if they plan to hold onto them for years. Some House Republicans say the rules have forced banks to report huge paper losses on mortgage-backed securities which might have been avoided.
