A Navy sailor stationed in Portsmouth is facing charges that he gave classified information to a Russian he knew.

Chief Petty Officer Charles T. Briggs is scheduled to be arraigned next week at a general court-martial. Military court documents don’t say what kind of information he’s accused of giving the Russian or how he knew the person.

Briggs, who works in information and technology at Naval Medical Center Portsmouth, is charged with unauthorized distribution of classified information obtained from a government computer, obstructing justice, communicating defense information, possessing child pornography, attempting to view child pornography, two counts of violating a general regulation and three counts of making false official statements.

According to the charge sheet, Briggs used a government computer to get secret information on or around Jan. 9, 2019, and had reason to believe the information could be used to “injure the United States or benefit a foreign national.”
