Lieutenant (junior grade) (LTJG) is a junior commissioned officer rank in the United States Navy. Did he go to Anapolis? The two year enlistment is suspicious, indeed.
Mabus was born in Starkville and is a fourth-generation Mississippian; he grew up in Ackerman, the only child of the owner of the local hardware store. After attending public schools, he graduated summa cum laude from the University of Mississippi, where he was a member of Beta Theta Pi, with a B.A. in English and political science. He earned an M.A. in political science from Johns Hopkins University and a Juris Doctor, magna cum laude, from Harvard Law School. He also served two years in the Navy as a surface warfare officer from 1970 to 1972 aboard the cruiser USS Little Rock,[1] and worked as a law clerk in the United States Fifth Circuit Court of Appeals.
