Paula Broadwell, a woman who was romantically involved with former CIA Director David Petraeus, will not face federal charges of cyberstalking another woman friendly with Petraeus. The U.S. Attorney's Office in Tampa informed Broadwell's attorney Robert Muse of the decision in a brief letter dated December 14. As the target of our investigation, we believe that it is appropriate to advise your client that our office has determined that no federal charges will be brought regarding allegations of cyberstalking, Assistant U.S. Attorney W. Stephen Muldrow wrote. Muse told CNN he was very pleased that the U.S. Attorney's office in Tampa very promptly resolved this matter. A source close to Broadwell said the letter had been received Monday. She's pleased with the prosecutor's decision and glad it's been resolved, the source told CNN. Petraeus resigned November 9 after revealing that he 'd been involved in an extramarital affair. U.S. officials said the FBI discovered Petraeus was involved with Broadwell, a woman who was under investigation for sending allegedly harassing and anonymous e-mails to Jill Kelley, a Tampa socialite who was friendly with Petraeus and his wife. Sources close to Kelley said she had not been romantically involved with Petraeus. During the investigation the FBI obtained Broadwell's computer and discovered she had classified materials.
