"While being filmed for a documentary, the president stumbled through his chosen passage, taking his frustration out on everyone around him, Philip Rucker and Carol Leonnig write...

"With LED lights on stilts in front of him, Trump took his seat. “You’re lucky you got the easy part,” (director Alexandra) Pelosi (daughter of House Speaker Nancy Pelosi) told him cheerfully. “It gets complicated after this.” But the president stumbled, trying to get out the words in the arcane, stilted form the founding fathers had written. Trump grew irritated. “It’s very hard to do because of the language here,” Trump told the crew. “It’s very hard to get through that whole thing without a stumble.” He added, “It’s like a different language, right?” The cameraman tried to calm Trump, telling him it was no big deal, to take a moment and start over. Trump tried again, but again remarked, “It’s like a foreign language.”

"The section, like many parts of the Constitution, was slightly awkward—an anachronistic arrangement of words that don’t naturally trip off the tongue. Members of the crew exchanged looks, trying not to be obvious. Some believed Trump would eventually get it, but others were more concerned. The president, already bristling about his missteps, was getting angry. He chided the crew, accusing them of distracting him. “You know, your paper was making a lot of noise. It’s tough enough,” Trump said.

“Every time he stumbled, he manufactured something to blame people,” another person in the room recalled. “He never said, ‘Sorry, I’m messing this up.’ [Other] people would screw up and say, ‘Ohhhh, I’m sorry.’ They would be self-effacing. He was making up excuses and saying there were distracting sounds.… He was definitely blaming everyone for his inability to get through it. That was prickly, or childish.” Though stiff, he eventually made it through without any errors.

"Trump presented a stark contrast to many other readers, including the Supreme Court associate justice Stephen Breyer, who read as if he knew the full text by heart, and Senator Ted Cruz, who “knew it from beginning to end” as a result of performing dramatic readings of the Constitution as a high school student, according to Pelosi. “Donald Trump is a celebrity and he came to perform,” she said. “He had not practiced it beforehand. I don’t think anyone would show up to read the Constitution without practicing it first.”
