You mean like Trumps own MOU that he went back on ?
Anyhow, "The art of the deal" did not work out for Americans either when he tried it on them.
""Judge Curiel's order finalizing the $25 million Trump University settlement means that victims of Donald Trump's fraudulent university will finally receive the relief they deserve," he said in a statement, adding that the amount surpassed the initial number the class-action suit initially negotiated."

Basically, it was pay to go to Trumps "University" and learn the art of the deal. That was a scam. $25 million is small change compared to the scams he is running now of course.
And lets not forget, " the art of the deal" man was convicted on 34 counts of fraud. He is a convicted fraudster.
Here is what Tony Schwartz, the guy who actually wrote the book, said -
"President Trump's former ghostwriter says writing "The Art of the Deal" is the biggest regret of his life and wishes the 1987 bestseller "weren't even in print."
"I knew this was a bad guy when I did the book," Tony Schwartz told CBS News chief Washington correspondent Major Garrett for this week's episode of "The Takeout" podcast. The pair sat down for lunch at New York's ViceVersa restaurant.
"Trump is not only willing to lie, but he doesn't get bothered by it, doesn't feel guilty about it, isn't preoccupied by it," Schwartz said. "There's an emptiness inside Trump. There's an absence of a soul. There's an absence of a heart.""

Re his telling lies, we just need to see his latest "Golf Championship win" from last week. It will be a struggle to find anyone who says he did not cheat to get a 2 under par round. And there is also the matter of him apparently not being able to tell the truth about anything. Just read ANY of his speech transcripts.
