COLUMBUS, Ohio (AP) — The leader of Ohio’s House of Representatives said Wednesday that lawmakers determining whether Attorney General Marc Dann should be impeached over a sex scandal need help from an unlikely source: the attorney general himself.

Republican House Speaker Jon Husted said the chamber isn’t well-equipped to investigate whether Dann has committed any impeachable offenses and could be helped by an independent investigator. Dann, Husted said, would be most able to quickly and efficiently make such an appointment.

There are several ongoing investigations stemming from the scandal. The information needs to be condensed, and possibly combined with information yet to be gathered, so the House can determine whether impeachment is warranted, Husted said.

‘‘Without having a mechanism to gather that information and to put that information together we are at a distinct disadvantage in being able to make a responsible decision,’’ he said.
