 Acknowledging the message, Mori resumed his round of golf, ending it an hour and a half after the first message, an action for which he was later heavily criticized, owing in part to the use of stock photographs taken the previous summer showing Mori enjoying his round of golf.Since the collision involved a commercial vessel, the U.S. National Transportation Safety Board (NTSB) had jurisdiction to conduct the investigation into the accident.An NTSB official, along with several USN and USCG officers, questioned Waddle and Pfeifer about the incident as soon as "Greeneville" moored at Pearl Harbor.
