President Barack Obama's health is fine a little more than a week after he traveled to Mexico, where an outbreak of swine flu has killed at least 68 people and sickened more than 1,000, the White House said Saturday. "The president's trip to Mexico has not put his health in any danger," said spokesman Robert Gibbs. The World Health Organization's director-general, Margaret Chan, said the outbreak of the never-before-seen virus is a very serious situation and has "pandemic potential." Obama was in Mexico last week to meet with top government officials and talk about the growing problem with drug smuggling and border violence. Obama is being updated on the swine flu outbreak in Mexico, with the Homeland Security Council monitoring the situation along with the State Department and the Centers for Disease Control and Prevention.
