“He’s been lying his whole life, almost reflexively, and it’s almost as if he finds it more satisfying and easier than to speak with precision,” said Michael D’Antonio, a Pulitzer Prize-winning reporter who later wrote a biography of Mr. Trump, “The Truth About Trump.” “When he was a kid, he lied about whether he hit a home run or not, and when he was a young man, he lied about how tall Trump Tower is — how many floors it is and the actual floors in feet — and he lied about which beautiful women were interested in him.”
Mr. Trump has written about how he bends the truth when it suits his purposes, asserting in his 1987 book “The Art of the Deal” that “a little hyperbole never hurts.”
“People want to believe that something is the biggest and the greatest and the most spectacular,” Mr. Trump wrote then. “I call it truthful hyperbole. It’s an innocent form of exaggeration — and a very effective form of promotion.”
The major difference now, Mr. D’Antonio said, is that as president Mr. Trump is fact-checked assiduously.
Mr. Trump’s latest tangle with the truth began on Monday, when he said at a cabinet meeting that Mr. Peña Nieto had been on the phone to him. “Even the president of Mexico called me,” Mr. Trump said, touting his success in cracking down on illegal immigration. “They said their southern border — very few people are coming because they know they’re not going to get through our border, which is the ultimate compliment.”
The Mexican government said on Wednesday that no such telephone call took place. In a statement, Mexico’s secretary of foreign relations said Mr. Peña Nieto told Mr. Trump during the Group of 20 summit meeting that deportations of Mexicans from the United States had fallen 31 percent over the first six months of the year, compared with the same period in 2016.
On Tuesday, it was the Boy Scouts’ turn: A leaked transcript of an interview the president had with The Wall Street Journal quoted him saying that the head of the Boy Scouts had called him full of praise for a highly political speech Mr. Trump had delivered at the National Scout Jamboree.
