Steve Roush has resigned from the U.S. Olympic Committee, leaving a post in which he played a key role in organizing logistics for American athletes at the last three Games.
Roush has been the USOC's chief of sport performance since 2003, and previously worked as sports partnership director.
The Colorado Springs-based USOC says the resignation is "effective this month."
In the six years leading to the Beijing Olympics, Roush made more than two dozen trips to China to ensure optimal conditions -- everything from living quarters, to food, to training facilities.
The 50-year-old Roush says he's been thinking and reflecting about pursuing new professional opportunities since the end of the Beijing Games.
