White House spokesman Trent Duffy said people who work in the executive mansion do have a sense of humor, but not when it comes to breaking regulations.
“When any official sign or seal is being used inappropriately the party is notified,” Duffy said.
“You cannot pick and choose where to enforce that rule. It’s important that the seal or any White House insignia not be used inappropriately,” he said.
Duffy said while he does not personally read The Onion, he admitted knowing others in the White House who do. “Like everyone else, we like a good laugh.”
