Paula Broadwell, the author who allegedly had an affair with former CIA Director David Petraeus, is suspected of storing significant amounts of military documents, including classified material, at her home, potentially in violation of federal law.

A source familiar with case told ABC News that Broadwell admitted to the FBI she took the documents from secure government buildings. The government demanded that they all be given back, and when federal agents descended on her North Carolina home on Monday night it was a pre-arranged meeting.

Prosecutors are now determining whether to charge Broadwell with a crime, and this morning the FBI and military are pouring over the material. The 40-year-old author, who wrote the biography on Gen. Petraeus “All In,” is cooperating and the case, which is complicated by the fact that as an intelligence officer in the U.S. Military Reserve she had security clearance to review the documents.

The FBI found classified material on a computer voluntarily handed over by Broadwell earlier in the investigation. Prosecutors will now have to determine how important the classified material is before making a final decision. Authorities could decide to seek disciplinary action against her rather than pursue charges.

Senior FBI officials are expected to brief the House and Senate Intelligence Committees today on their handling of the Petraeus investigation. The officials are expected to lay out how the case was developed and argue that there were no politics involved.

The case is so critical that FBI Director Robert Mueller may attend to defend the bureau, ABC News has learned. Members of Congress have been angry that they were not informed about the case before the story was reported by the media, but FBI officials maintain that their guidelines forbid them from discussing ongoing criminal cases.
