WASHINGTON (AP) — An aide to President Bush has resigned because of his alleged misuse of grant money from the U.S. Agency for International Development when he worked for a Cuban democracy organization.

Felipe Sixto was promoted on March 1 as a special assistant to the president for intergovernmental affairs and stepped forward on March 20 to reveal his alleged wrongdoing and to resign, White House spokesman Scott Stanzel said on Friday. He said Sixto took that step after learning that his former employer, the Center for a Free Cuba, was prepared to initiate legal action against him.

The alleged wrongdoing occurred when Sixto was chief of staff at the center, where he worked for more than three years before moving to the White House.
