The General Services Administration deputy commissioner who joked on video about the extravagant spending at the GSA's 2010 Las Vegas conference has been placed on leave, reports the Washington Post. David Foley is under disciplinary review for his conduct at the conference, making him the eighth GSA official so far to be disciplined or fired since the Vegas debacle came to light in a report by the Inspector General. "Our agency continues to be appalled by this indefensible behavior, and we are taking every step possible to ensure that nothing like this ever happens again,” said a GSA spokesman.
