The investigation by attorneys general in all 50 U.S. states into banks’ foreclosure practices is on “a fast track,” and any resolution might involve multiple settlements, Iowa Attorney General Tom Miller told Bloomberg. “We’d like to resolve this sooner rather than later,” Miller, who is leading the attorneys general task force, said in an interview Tuesday. “We want to move quickly if we can, but not so quickly that we don’t do it right.” A global settlement of the task force investigation is unlikely, he said; “It would be one bank at a time.” Miller also leads a separate foreclosure prevention group of state attorneys general.
