Video Shows Federal Officials Joking About Cost of Lavish Conference

Officials with the federal agency now under congressional investigation over a lavish conference were captured on camera joking about the expense at the summit's "capstone" event in October 2010.

One official joked about how much was spent at a party hosted by the agency's commissioner. Another employee, in a mock music video, even sang about how he'd "never be under OIG investigation."

OIG stands for Office of Inspector General -- the office that earlier this week released a bombshell report that triggered firings at the agency that held the conference. The report found the Public Buildings Service, part of the General Services Administration, spent more than $820,000 on the meeting near Las Vegas in 2010.
