WASHINGTON (AP) -- President George W. Bush is expressing remorse that the global financial crisis has cost jobs and damaged retirement accounts.

The president told ABC's "World News" in an interview that he will support additional federal intervention, if necessary, to ease the recession. The interview will air Monday night.

Bush told the network: "I'm sorry it's happening, of course."

The National Bureau of Economic Research reported on Monday that the U.S. economy fell into a recession in December 2007.
