WASHINGTON — The Air Force has ordered a review of its procedures used to decide where personnel are put up during overnight layovers, after conceding on Sunday that the decision to place a crew at the luxury resort owned by the Trump family in Scotland this year “might be allowable but not advisable.”

The internal inquiry is being conducted at the request of Air Force leadership, which has directed the Air Mobility Command “to review all guidance pertaining to selection of airports and lodging accommodations during international travels.”

[Update: Pentagon says it spent $184,000 at Trump’s Turnberry resort in Scotland.]

This comes after the Air Force decided in March to send seven crew members flying on a C-17 military transport plane that was on its way to Kuwait from Alaska to the Trump Turnberry resort in Scotland, after the plane had a layover at an airport nearby.

On Saturday, an Air Force official defended the decision to place the crew at the Trump resort, saying that there were no other closer rooms available and that the discounted rate the resort charged meant the cost was below a spending limit.
