The General Services Administration's Western Regions Conference scandal still leaves a bad taste in the mouths of some agencies. Spending on government conferences dropped $3 billion between 2013 and 2010. And the Office of Management and Budget told agencies to cut travel spending by 30 percent back in 2012. But federal employees gain some benefits from conferences that money can't buy. Bob Hale is a fellow at Booz Allen Hamilton, former undersecretary of defense comptroller and former executive director of the American Society of Military Comptrollers. He tells In Depth with Francis Rose why conferences are still valuable.
