Many details about foreign presidential trips are classified for national security reasons, and there is little public information about overall costs. A report from the Government Accountability Office found that Clinton’s 1998 trip to six African nations cost the U.S. government at least $42.7 million. Most of that was incurred by the military, which made 98 airlift missions to transport personnel and vehicles, and set up temporary medical evacuation units in five countries.
That figure did not include costs borne by the Secret Service, which were considered classified.
Obama’s trip could cost the federal government $60 million to $100 million based on the costs of similar African trips in recent years, according to one person familiar with the journey, who was not authorized to speak for attribution. The Secret Service planning document, which was provided to The Post by a person who is concerned about the amount of resources necessary for the trip, does not specify costs.
