Sandy Berger is going to plead guilty to illegally removing documents from the National Archive: Berger to Plead Guilty to Taking Materials. (No less than seven emails about this one; thanks to all.)

WASHINGTON - Former national security adviser Sandy Berger will plead guilty to taking classified material from the National Archives, a misdemeanor, the Justice Department said Thursday.

Berger is expected to appear in federal court in Washington on Friday, said Justice spokesman Bryan Sierra.

The former Clinton administration official previously acknowledged he removed from the National Archives copies of documents about the government’s anti-terror efforts and notes that he took on those documents. He said he was reviewing the materials to help determine which Clinton administration documents to provide to the independent commission investigating the Sept. 11, 2001, terror attacks.

He called the episode “an honest mistake,” and denied criminal wrongdoing.

Berger and his lawyer, Lanny Breuer, have said Berger knowingly removed the handwritten notes by placing them in his jacket and pants and inadvertently took copies of actual classified documents in a leather portfolio. He returned most of the documents, but some still are missing.
