Bernanke says top regulators digging deeper into banks' robo-sign scandal

Federal Banking regulators are conducting an intensive probe of reportedly false foreclosure affidavits used by major U.S. financial institutions to evict thousands of American homeowners.

"The federal banking agencies are working together to complete an in-depth review of practices at the largest mortgage servicing operations," Federal Reserve Chairman Ben Bernanke said Monday in the prepared text of a speech at a conference on foreclosures and the future of housing. "We are looking intensively at the firms' policies, procedures, and internal controls related to foreclosures and seeking to determine whether systematic weaknesses are leading to improper foreclosures."
