Corruption Scandal
On 8 November 2013, the Navy suspended Branch's access to classified information in connection with a Department of Justice investigation involving Singapore-based defense contractor, Glenn Defense Marine Asia. The investigation as to Branch involves a non-criminal accusation of "inappropriate conduct" associated with his acceptance of gifts from Glenn Marine during his tour as commanding officer of USS Nimitz on a western Pacific/Persian Gulf deployment in 2005. Although Branch remained in his post during the lengthy Justice Department investigation, his access to classified information remained suspended, relegating him to unclassified duties. In September 2015, the Navy formally nominated Rear Admiral Elizabeth L. Train to succeed Branch as Director of Naval Intelligence. In January 2016, the Washington Post reported that Branch was still functioning in his role, yet was "barred from reading, seeing or hearing classified information since November 2013", due to the suspension tied to the investigation. Also in January 2016, the Daily Mail reported, "Branch is yet to be charged, but he has not been cleared either - leaving the Navy in the bizarre predicament of having an intelligence chief who is unable to read top secret documents." On 1 April 2016, the Navy Times reported that the Navy had withdrawn Elizabeth Train's nomination to succeed Branch in favor of Vice Admiral Jan E. Tighe, previously commander of the Navy's Fleet Cyber Command and Commander, U.S. Tenth Fleet. Vice Admiral Tighe relieved Branch as Deputy CNO for Information Warfare/Director of Naval Intelligence in July 2016. Branch's access to classified information remained suspended until he retired. Both the Navy and the Department of Justice cleared Branch of any wrongdoing in September 2017 and declined to prosecute Branch after a three-year investigation that resulted in no charges being brought.
