Secretary of Labor Elaine Chao will replace Secretary of State Condoleezza Rice as head of the president's delegation to the Beijing Olympics at the games' closing ceremony Saturday, the White House announced this afternoon.

Rice's "travel schedule has changed due to developing world events," the White House press office said. Presumably, those events include Russia's conflict with Georgia and Pakistani President Pervez Musharraf's resignation. Rice traveled to Brussels yesterday for a North Atlantic Treaty Organization (NATO) meeting on the Georgia/Russia conflict.
