A former senior official with the National Security Agency faces sentencing in one of a series of criminal cases the Obama administration has pursued against government officials accused of giving classified information to the media.

Thomas Drake was originally charged with multiple felonies in the case, which the federal government brought after he leaked inside information on a failed NSA computer project to The Baltimore Sun.

Drake challenged the government’s claim the information he gave the newspaper was classified. The government’s case fell apart in June when the judge ordered it to put classified documents into evidence.

Drake pleaded guilty to a single misdemeanor charge of unauthorized access. His lawyers say they’ll ask Friday for a year’s probation and community service when he’s sentenced in Baltimore.
