American banks under scrutiny

American officials are looking into allegations that mortgage lenders acted illegally when they foreclosed on hundreds of thousands of homeowners.

The accusation is that firms signed off on home foreclosures, without going through the correct procedures.

The banks could be in hot water if the investigation uncovers criminal acts or that top executives were aware of the robo-signing.
