U.S. civil rights leader Al Sharpton said Thursday that Mexico's president still needs to apologize for saying Mexicans take jobs in the United States that "not even" blacks will do. In a phone interview with The Associated Press, Sharpton said he wasn't satisfied with the contradictory expressions of regret issued by the administration of Vicente Fox this week. He said he would seek an "unequivocal, formal" apology during a meeting with Fox on Monday in Mexico City. The president's spokesman, Ruben Aguilar, has characterized the comment, made May 13 during a visit to Puerto Vallarta, as a misunderstanding. His office refused to comment on Sharpton's demand Thursday. The closest the administration has come to apologizing was when Assistant Foreign Secretary Patricia Olamendi said Tuesday that "if anyone felt offended by the statement, I offer apologies on behalf of my government." But the next day Aguilar said Olamendi was speaking on behalf of herself _ not the government.
