Sanford, a captain in the Reserve, could have been reprimanded over his heavily publicized extramarital affair with an Argentine woman. As the Greenville News reports, adultery is punishable under military code.
Air Force Reserve Command spokesperson Cliff Tyler said the Reserve "looked at all the facts and they looked at the circumstances and the decision was made as a command not to take any action against him."
Sanford spokesman Joel Sawyer said he had no comment on the decision. He told the newspaper that the governor is "looking forward, not backward."
Sanford joined the Air Force Reserves in 2002.
