While working for three years at as chief of staff of the Center for a Free Cuba, a U.S. government-funded center that promotes democracy in Cuba, Felipe Sixto made more than $579,000 for himself by overcharging the group for radios and flashlights.

Then in July 2007 Sixto got a job in Bush’s White House Office of Intergovernmental Affairs where he was assigned to deal with state legislators, Native American groups and Hispanic officials on issues such as Cuba, Puerto Rico, health, labor, transportation, the environment and energy, according to the Associated Press.

He was promoted to to special assistant to Bush on March 1, and just weeks later learned that his former employer was prepared to begin legal action against him, at which point he resigned his post.

Friday Sixto plead guilty to theft from a federally aided program. He will be sentenced in the spring.
