In his new book, the former Secretary of Defense wrote that Donald Trump used to complain about how the US Navy ships looked and compared them to Russian and Italian vessels.
According to an excerpt released by The Hill, the president dislikes the Navy's vessel designs.
Trump privately complained that the Navy's ships looked ugly and that their Russian and Italian counterparts looked like real ships.
The Navy is built to fight and win, not win beauty contests, and we prize function over form, according to the man who defended the Navy.
"That didn't satisfy him and he reacted in a different way," said Esper, describing Trump's reaction to his rebuttal.
Over the last few weeks, excerpts of the book have been published.
The New York Times reported on Friday that Trump once suggested that the US launch missiles into Mexico to destroy the drug labs.
According to The Times, Stephen Miller, a former White House senior adviser to Trump, wanted to show off the head of the leader of the Islamic State. He said that the act would be a war crime.
Another excerpt from the book was released on May 2, and it showed how Trump asked officials if it was possible to shoot the protesters.
Other Trump-era officials, including former Attorney General William Barr and former White House press secretary, have also released behind-the-scenes recollections of the Trump administration.
Grisham's book, titled "I'll Take Your Questions Now: What I Saw At The Trump White House," includes stories such as how Trump wore her makeup during a speech in Saudi Arabia.
