Former vice-presidents Joe Biden and Dick Cheney, former Speaker of the House of Representatives, Newt Gingrich, and the Supreme Court Justices Ruth Bader Ginsburg and Clarence Thomas have all had trouble in the past staying awake during meetings, and US Commerce Secretary Wilbur Ross has also been said to be fond of "a crafty forty winks".
When President Donald Trump, fell asleep during one of his own speeches yesterday, however, he vehemently denied having nodded off, and said he was just concentrating on his words. With his eyes closed.
Trump was speaking about something or other at the White House, when, all of a sudden, he stopped speaking, and started mumbling. His eyelids fluttered a few times, as if his eyes were madly trying to stay open against a tidal wave of tiredness, finally admitting defeat. There was drool.
To all intents and purposes, President Trump was now in the Land of Nod. Several seconds passed.
Then, and not a moment too soon, a fly landed on his top lip. The president brushed it away, and started speaking again. After a few more incoherent words, however, he resumed his reverie, and had to be shaken awake by White House aides.
He looked around him confusedly, like a mad old man protesting, being manhandled back to his hospital bed after imagining a doctor had agreed to let him go home.
Later, nearer bedtime, Trump got busy on Twitter:
"I wasn't sleeping, I was just resting my eyes," he lied. "If you new about just how bizzy I am, and about all the big decisions I have to make to make America grate again, you'd no I need to rest my eyes. Goodnight!"
And he laid his sweet little orange head down on his duck-feather pillow, and fell into a deep sleep from which we must all pray he never awakes.
