Under fire over reports that EPA Administrator Scott Pruitt took several first class flights using taxpayer money, the agency defended the flights on Tuesday by claiming that Pruitt had a “blanket waiver” to fly first class for security reasons, only to walk back that claim the next day.

Several reports this week revealed that Pruitt flew first class on flights from Washington, D.C. to Boston and Washington, D.C. to New York, as well as on an Emirates flight from Milan, Italy, to Washington, D.C. Pruitt said on Tuesday that he felt he had to fly first class due to the “level of threat” he faces on planes. EPA Spokesman Jahan Wilcox also said Tuesday that Pruitt had a “blanket waiver” to do so.

However, when Politico pointed out that rules prohibit blanket waivers, Wilcox changed his statement and said that the EPA submits waivers each time Pruitt needs one.

“As such, for every trip Administrator Pruitt submits a waiver to fly in either first or business class,” Wilcox said in a statement to Politico.
