A man who in the 1980s was convicted of espionage and later pardoned for leaking spy satellite photos to a British magazine is scheduled to plead guilty to charges of stealing government records.

Online court records show Samuel Loring Morison of Crofton, Maryland, is scheduled to plead guilty Thursday to charges of stealing records related to his grandfather, the late Rear Adm. Samuel Eliot Morison.

The elder Morison wrote a seminal history of World War II naval operations and was a two-time recipient of the Pulitzer Prize. He died in 1976.

Samuel Loring Morison was arrested in 2014 and charged with stealing the records from the Naval History and Heritage Command in Washington.

Morison's attorney, Jim Wyda, declined to comment Wednesday.
