WASHINGTON – The Justice Department has decided not to charge David Petraeus' mistress, Paula Broadwell, with cyberstalking as part of its investigation into an email scandal that led to the resignation of the CIA director and storied general.

Broadwell's lawyer, Robert Muse, gave The Associated Press a letter from U.S. Attorney Robert O'Neill that said no federal charges will be brought in Florida related to "alleged acts of cyberstalking."

Petraeus resigned as CIA director in November after acknowledging the extramarital affair, which was exposed after Broadwell emailed Tampa socialite Jill Kelley, allegedly warning Kelley to stay away from Petraeus and Gen. John Allen, the U.S. commander in Afghanistan.
