Washington (CNN) -- The Pentagon is bracing for the release of more secrets by the whistleblower website WikiLeaks, a Pentagon official said Tuesday, as the Defense Department drafts a new plan to securely distribute and protect military and other information.
Pentagon spokesman Col. Dave Lapan said WikiLeaks has more Defense Department material beyond what site founder Julian Assange has admitted publicly to possessing.
"We believe that WikiLeaks has in its possession additional documents that may be released in the future," Lapan told reporters at a briefing. "They still have the 15,000 documents from Afghanistan. They still have a video from Afghanistan. Those are things they have talked about publicly."
"And we have reason to believe they have other documents as well," he added, without elaborating.
The military has charged Pfc. Bradley Manning with leaking video to WikiLeaks, as well as downloading documents from military computers while he served as an intelligence analyst in Iraq. Among the documents he is alleged to have taken are 150,000 diplomatic cables. WikiLeaks has denied being in possession of those cables. Manning is currently being held at a military jail in Quantico, Virginia.
