Mary, the niece of US President Donald Trump, described her uncle as someone likely to suffer from many psychological disorders, which does not make him fit to be president of the United States.

This came in memoirs of Mary Trump that I included in a book called "Too Much and Never Enough: How My Family Made the Most Dangerous Man in the World" (Too Much and Never Enough: How My Family Created the World's Most Dangerous Man) Media before it is published.

Mary is the daughter of President Trump's older brother, Fred Trump, who died of a heart attack at the age of 42 as a result of alcoholism. Mary holds a PhD in clinical psychology from Adelphi University in New York.

Robert, the younger brother of the President of the United States, tried to prevent the book from being published, but a judge in New York decided last week to allow the publication "Simon & Schuster" to print the book, which will be presented in libraries weeks before the Republican National Convention, where he is expected to accept it. Donald Trump nominates the party to run in the race for his re-election to the presidency in November.

For her part, White House press spokeswoman Kylie McKinney on Tuesday described the book as "full of lies. And that's it."

Commenting on the book, White House spokeswoman Sarah Matthews said, "Mary Trump and the publishing house may claim that they are acting in the public interest, but the book is clearly in the personal financial interest of the author."

The daily POLITICO, published in Washington, DC, summarized nine accusations that it described as the most scathing in Mary Trump's book:

1- Trump prankster

Mary Trump accused the president of paying money to a friend for taking the college entrance exam "SAT" on his behalf to help him enter the University of Pennsylvania.

The SAT test, according to the Wikipedia online, is a basic test for American college enrollment, and is one of the tests the military uses to test an individual's mental abilities.

2- Trump the clown

Mary notes in her memoirs that Marian Trump Barry, a former judge on the Court of Appeals of New Jersey and the elder sister of the American president, saw her brother "clown" who would never be able to win the presidency.

At a luncheon with the author of the book after Donald Trump announced in 2015 his intention to run in the presidential election, Marianne described her brother as "absolutely without principles", and that "the only time Donald was going to church when there were cameras."

Marianne also noted that her brother's business was bankrupted five times, and that he was taking advantage of his brother Farid, Mary’s deceased father.

3- Trump did not know his son's wife

In her memoirs, Mary says that Donald Trump has not recognized his wife's wife, Lara, Erik, despite their association with marriage for nearly eight years.

4- Trump is mentally disturbed

Besides believing that her uncle meets the nine criteria of clinical narcissism, Mary Trump sees that he may also suffer from antisocial personality disorder, dependent personality disorder, and a learning difficulty that has hindered his ability to process information for decades.

He also - according to Mary - may have a sleep disorder caused by excessive intake of "diet diet" drinks on a daily basis that contain stimulant caffeine.

5- Marianne Barry's advice to her brother Trump before meeting with the North Korean leader

Mary mentioned in her book that Marian Trump Barry called the White House in June 2018 to warn her brother of the consequences of his dealings with North Korean leader Kim Jong Un before meeting him.

"Tell him that his older sister called to inform him of brotherly advice that I prepare (for the interview) and learn who knows what to do. Leave the Twitter behind. Avoid Dennis Rodman (the famous American basketball player who considered himself a friend of Kim)," Barry told the president's secretary in the call.

6- Trump's relationship with his mother

The author of the book claims that Donald Trump's personality was formed through his weak relationship as a child with his mother, Mary.

Because of that relationship - the president's niece adds in her diary - Donald's money as a child toward his father who was not a friendly father.

Mary says in her book that "Donald suffered from deprivation, which will have a lasting impact throughout his life," so that his character was characterized by a personality such as "narcissism, bullying and a sense of greatness."

7- Trump's father and anti-Semitism

The author of the book notes that Farid the Great, the father of Donald Trump, and the real estate tycoon in New York used to use anti-Semitic terminology in his conversations.

The US government filed a lawsuit against Fred Trump, father and son Donald, in the early 1970s for allegedly discriminating against African Americans.

8- Trump and a history of crude comments

When authoring the second part of his book, "Trump: The Art of the Deal," Trump complained that women did not want to date him, describing them as "the dirtiest, ugliest and most obese person."

9- Trump is indifferent

In her memoirs, Mary reported that Trump took his sister, Elizabeth, to the movie theater to watch a movie while his brother - her father, Farid - was dying in hospital in 1981, adding that no family member accompanied her father to the hospital.
