HARRISBURG, Pa. — Pennsylvania's state treasurer has resigned and plans to plead guilty to federal charges accusing him of using his office to threaten potential campaign donors during his failed gubernatorial primary race last year.

Democrat Rob McCord apologized for his actions in a video statement released by his lawyers Friday and resigned immediately.

His lawyers say he'll plead guilty and that charges could be filed as early as next week.

McCord is the second statewide official in Pennsylvania facing some sort of official scrutiny. Attorney General Kathleen Kane potentially faces charges for allegedly giving secret investigative material to a newspaper.
