The White House approved the use of military aircraft for multi-national trips by Health and Human Services Secretary Tom Price to Africa and Europe this spring, and to Asia in the summer, at a cost of more than $500,000 to taxpayers.

The overseas trips bring the total cost to taxpayers of Price’s travels to more than $1 million since May, according to a POLITICO review.

Price pledged on Thursday to reimburse the government for the cost of his own seat on his domestic trips using private aircraft – reportedly around $52,000 — but that would not include the cost of the military flights.

Price’s wife, Betty, accompanied him on the military flights, while other members of the secretary’s delegation flew commercially to Europe.
