WASHINGTON (AP) — The Navy admiral fired last fall as the No. 2 commander of U.S. nuclear forces was given a letter of reprimand Monday and ordered to forfeit $4,000 in pay but will be allowed to remain on duty as a Navy staff officer, the Navy said.

In a brief statement, the Navy said a superior officer determined that Rear Adm. Timothy Giardina’s involvement in a casino gambling case violated the Uniform Code of Military Justice on two counts of conduct unbecoming an officer and a gentleman.
