is postponing a planned trip to Israel.
The decision comes as Pruitt is under pressure over the cost of his travel, including frequent first-class flights. The postponement of the Israel trip was first reported by The Washington Post.
EPA spokeswoman Liz Bowman confirmed the trip's postponement in an email Sunday. She did not explain why the trip had been postponed or immediately respond to an email asking whether the decision was related to the recent reports about Pruitt's travel.
Pruitt has said a "toxic environment politically" required first-class travel and protection from a 24-hour security detail.
According to travel vouchers obtained by an environmental organization, Pruitt and staffers billed taxpayers nearly $200,000 for his trips over six months last year.
CBS News had learned that when Pruitt returned home from Milan on June 11, he flew on Emirates Airlines, whose business class cabins are some of the world's most luxurious, complete with an onboard lounge that promises what the airline calls a "truly unique journey."
To take the flight, Pruitt needed special dispensation. Government officials are bound by the Fly America Act, which requires them to "use U.S. air carrier service for all air travel… funded by the U.S. government."
Sources have told CBS News that Pruitt regularly flies in first class along with his unprecedented, round-the-clock, security detail. The costs of their travel has not been made available.
