Lt. Easterling is a petitioner in a court suit. This does not constitute violation of Art. 88, but his alleged remarks do.

He was in KBR, and joined the Army at age 40, commissioned Lieutenant, and is on a 15-month tour of duty. I don't know if he had military service prior to joining KBR.

However, his remarks in a letter to Attorney Orly Taitz have been released (NBC News); they violate provisions of the UCMJ in that he allegedly said he would refuse Obama's military orders.
