Prosecutor Josh Steinglass read back some of the quotes from Trump's books to highlight Trump's frugality and micromanaging.
Steinglass mocked the defense argument that Trump didn't have control over the words in the books he wrote.
Steinglass compared it to a Yogi Berra quote: "I really didn't say everything I said," which drew laughs from the jury.
"He doesn't like spending money, and he's proud of it," Steinglass said of Trump, reminding jurors that David Pecker testified to this as well. He's a "micromanager" who "insists on being involved in the details" of his business, Steinglass said.
Steinglass quoted from Trump's book, "Think Like A Billionaire," which urged readers to "pay attention to the small numbers in your finances" and called frugality the "most important money management skill a person can use."
"That has been his philosophy from the beginning," Steinglass said. "The cardinal sin for Mr. Trump is overpaying for anything."
Steinglass read one quote where Trump emphasized to always check invoices, including from decorators.
"If Donald Trump is checking the invoices from his decorator, you can bet he is checking his invoices from Michael Cohen," Steinglass said.
