The head of the Smithsonian Latino Center resigned after an investigation found she abused her expense account to fund her extravagant use of spas, luxury hotels and frequent limousine rides, according to a report released by the institution.

Pilar O'Leary, 39, billed the museum for "extravagant" and "lavish travel expenses," the Smithsonian Institution inspector general found.

O'Leary also solicited free tickets to events including, the Latin Grammys and the Billboard Latin Music Awards and Conference, the report said.

According to the report, "The investigation revealed that O'Leary has not always acted in the best interests of the Smithsonian" and "Her conduct has violated the basic ethical rules of the Institution."

According to the Washington Post, which received the report following a response to a Freedom of Information Act request, O'Leary denied any wrongdoing, saying her travel had been approved by supervisors and the tickets weren't gifts.

O'Leary left the Smithsonian in February, and at the time the institution made no mention of the ethical violations.
