After two days of silence, the top general in Afghanistan says he will "fully cooperate" with the investigation ordered into communications he had with a Tampa socialite at the center of the military's sex scandal.

Marine Corps Gen. John Allen released a statement through his lawyer Wednesday night saying he'll cooperate and that he instructed his staff to do the same.

The lawyer, Col. John G. Baker, says Allen wants questions in the probe resolved as quickly and completely as possible.

The Pentagon inspector general is looking into emails exchanged between Allen and Jill Kelley. The inquiry came after Kelley complained about another matter - emails sent to her by the woman identified as the mistress of former CIA Director David Petraeus.
