The spiraling scandal that took down former CIA Director David Petraeus has apparently ensnared another powerful general, as authorities announced that Gen. John Allen is under investigation for allegedly sending inappropriate messages to Jill Kelley, a woman who has been linked to the Petraeus scandal.
Allen, who is the commander of NATO's International Security Assistance Force, has denied any wrongdoing, a senior defense official said.
Details of the latest angle of the scandal that has shaken the highest level of the military were sketchy early Tuesday.
Some details about Allen, the top U.S. commander in Afghanistan, came from an overnight statement by Defense Secretary Leon Panetta, while he was on his way to Australia.
This morning on "Early Start," CNN's Chris Lawrence reports on the latest.
