An Air Force official admitted the branch’s multiple purchases of coffee cups that break easily and cost $1,280 each “is simply irresponsible,” vowing to pursue ways to fix the mugs instead of continually buying new ones.

Buying and replacing the special mugs, which can reheat liquids aboard air refueling tankers in flight, has cost the Air Force $326,785 since 2016, Air Force Secretary Heather Wilson said in a letter.

The letter, dated last Wednesday to Sen. Chuck Grassley, R-Iowa, came after Grassley questioned “yet another report of wasteful spending in the Department of Defense” in an earlier letter.
