Judicial Watch, the public interest group that investigates and fights government corruption, announced today that it obtained documents from the United States Air Force and the United States Secret Service detailing costs associated with Michelle Obama’s controversial August 2010 vacation to Spain. According to a Judicial Watch analysis, the records indicate a total combined cost of at least $467,585.

She got a vacation and she didn't pay for it. Fits the definition perfectly.

According to U.S. Department of Defense’s 2010 published hourly rates, the total cost of flying Michelle Obama and her guests from Camp Andrews to Malaga and then to Mallorca and back to the United States was $199,323.75. This is based on approximately 17 hours and 15 minutes of total flying time. The 15-member flight crew stayed at Tryp Guadalmar, a nearby motel. Lodging cost was $10,290.60 and car rental cost was $2,633.50. Food cost was $876.30, including $57.68 for four bottles of maple syrup and a package of pancake mix.
