A former aide to then-President George W. Bush used money he stole from a government-funded nonprofit to pay student loans and credit card debt and to purchase a car, a truck, a piano and artwork, according to documents filed this month at the U.S. District Court for the District of Columbia.

Felipe E. Sixto, 29, who was an associate director at the White House Office of Intergovernmental Affairs, also spent $50,000 on groceries and restaurants, paid $142,000 to family members, and used $82,000 for a mortgage payment and another $19,000 for medical bills, the documents show. The detailed spending was listed in a 26-page memorandum seeking leniency filed by Kathleen E. Voelker, a Washington lawyer representing Sixto. She said that Sixto had made restitution to the Center for a Free Cuba, or CFC, a nonprofit that promotes democracy in Cuba.

In December, Sixto pleaded guilty to stealing $579,247 in U.S. Agency for International Development funds from the CFC. He is scheduled to be sentenced Wednesday. Prosecutors, in a court filing, said that Sixto engaged in the theft while serving as CFC's chief of staff and continued carrying out his scheme after he joined the White House in July 2007. As part of his scheme, the government said, Sixto set up a bank account, incorporated a company in Maryland, and used the alias, "Walter Lee.''

Sixto, the government said, used the stolen funds "to live a lifestyle that was beyond his means.'' His conduct, prosecutors said, "had a tremendous and lasting impact on CFC.'' Shortly after CFC reported the loss of money to AID, the nonprofit's government funding was suspended. Some CFC employees were forced to work without pay while others were terminated, the government said. AID reinstated the nonprofit, which has filed a new application for funding.
