A federal law enforcement official confirmed the FBI is now looking at 26 cases of potential corporate fraud related to the collapse of the U.S. mortgage lending industry.
FBI Director Robert Mueller told the U.S. Congress a week ago that 24 cases of potential corporate fraud were under investigation, up from 21 disclosed by the bureau in July.
In testimony before the House of Representatives Judiciary Committee, the FBI chief also vowed to pursue corporate executives if necessary in mortgage fraud cases.
Mueller said the FBI was looking at all levels of the mortgage systems. With respect to the corporate probes, which could result in federal charges, "the allegations would be there were misstatements of assets," he said.
