"A collapse of investment bank Bear Stearns would have been fell on Main Street, not just Wall Street." That's what Fed Chair Ben Bernanke told the Senate Banking Committee this morning.

The Fed Chair says allowing Bear Stearns to collapse would have spelt disaster for the US economy. Critics of the deal say it amounts to a taxpayer back to bailout of Bear Stearns.

Some good news and bad news for President Bush today at the NATO Summit, convening in Romania, NATO leaders bow to pressure from Russia and deny earlier admission to the former Soviet states of Ukraine and Georgia.

The President will also be pleased that NATO invited Croatia and Albania to become alliance members.
