It cost taxpayers nearly a half-million dollars for first lady Michelle Obama to travel to Spain in 2010, according to an analysis by Judicial Watch.

The right-leaning watchdog group estimated that the trip cost $467,585. It based its analysis on documents obtained from the U.S. Secret Service and the U.S. Air Force.

Judicial Watch President Tom Fitton said it took his group “two years and a lawsuit to get these documents out of the Obama administration.”

“It is hypocritical for President Obama to fire GSA officials for wasteful conference spending, while his family went on a luxury vacation in the Costa del Sol Spain that cost taxpayers nearly half a million dollars,” Fitton said.
