Secretary of State Marco Rubio has revealed how he hides from Donald Trump aboard Air Force One in order to get some rest.

In a lengthy profile examining Trump’s health published Monday by New York Magazine, Rubio described his weird strategy to avoid being spotted by the president during flights.

“There’s an office with two couches, and I usually want to sleep on one of those two couches,” Rubio told the magazine’s Washington correspondent, Ben Terris.

“But what I do is I cocoon myself in a blanket. I cover my head. I look like a mummy,” he added. Terris noted that Rubio demonstrated by “pulling a blanket over his body as if he were auditioning for a Snuggie commercial.”

Rubio said the tactic is necessary because Trump rarely sleeps on the presidential jet. “Because I know that at some point on the flight, he’s going to emerge from the cabin and start prowling the hallways to see who is awake,” he explained.

“I want him to think it’s a staffer who fell asleep,” he added. “I don’t want him to see his secretary of state sleeping on a couch and think, ‘Oh, this guy is weak.’”

Trump’s minimal sleep habits are well documented.

The president has long boasted about getting by on little rest, once telling supporters during his 2016 campaign: “I’m not a big sleeper. I like three hours, four hours, I toss, I turn, I beep-de-beep, I want to find out what’s going on.”

Close allies have said Trump often calls them in the early hours of the morning.
