The attorneys general of up to 40 states plan to announce soon a joint investigation into banks' use of flawed foreclosure paperwork.


A person briefed on the investigation said Saturday night that an announcement could come as early as Tuesday. The person spoke on condition of anonymity because the investigation was not yet public.

Iowa Attorney General Tom Miller will lead the investigation. Miller already has been leading multistate reviews of questionable foreclosure documents.

A joint investigation by 40 states would further escalate pressure on banks to widen their suspensions of foreclosures. On Friday, Bank of America became the first bank to halt foreclosures in all 50 states.
