Marine Maj. Mark Thompson, the former U.S. Naval Academy instructor charged with lying in a sexual misconduct case, is set to plead guilty this week, military court records show.

Thompson was slated to stand trial this week, but instead, a plea hearing is scheduled for Thursday morning at Marine Corps Base Quantico, according to the military’s online court docket and a military official.

Thompson, who faces charges of making a false official statement and of conduct unbecoming an officer and a gentleman, had long sought to clear his name by proving that he was unfairly convicted of sexual misconduct with two female midshipmen at a 2013 court-martial. He brought his allegations to The Washington Post.

The military launched a new investigation into Thompson and filed additional charges after The Post uncovered evidence that he was dishonest when he testified before an administrative board deciding whether he should be kicked out of the Marines.

After the new charges were filed, Marine prosecutors said Thompson should be locked up for nearly three years, fined $200,000 and removed from the service for what they described as a pattern of deception. At 47, Thompson also faces a total loss of his retirement benefits.
