Mary Trump, a niece of President Donald Trump, wrote a controversial book about him titled “Too Much and Never Enough” and writer and co-host of “The View” Meghan McCain asked her about her intention in writing it.

McCain asks directly if it would have been a way to “get a paycheck,” and she said that when the subject is familiar, it is difficult to test the veracity of the story because it reflects only the author’s point of view, which she said would undermine her credibility, according to ABC News on July 23.

“I don’t like family tell-all books … because they’re told from the one side, and often the subjects are villainized to the point that I don’t actually end up believing the stuff written,” McCain pointed out to Mary Trump.

In a tweet that contains part of the interview, part of Mary’s intervention appears in reference to money.

“Meghan McCain to Mary Trump, ‘What do you say to people like me who think this is just a great way for you to get a paycheck right now?’”

“Trump, ‘If I had wanted to cash in… I would have done this ten years ago… and I would not have been taking the risks that I’m taking,'” Mary Trump responded in the interview.

The fact is that sales of the controversial book have reached 1.35 million copies, according to a report by publisher Simon and Schuster.

Meghan also highlighted the fact that Mary Trump did not frequent the president’s family and barely knew her cousins, which was also alluded to by her uncle and president, who also accused her of breaking the law by violating the confidentiality agreement, in a July 17 tweet.

“Will all end up going to the government anyway. Next up is Mary Trump, a seldom-seen niece who knows little about me, says untruthful things about my wonderful parents (who couldn’t stand her!) and me, and violated her NDA. She also broke the Law by giving out my …” Trump said, continuing in another message.

“Tax returns. It’s a disaster! A lot of books have been written about me, some good, some bad. Both happily and sadly, there will be more to come,” downplaying one more book written about him.

Mary Trump’s book states in the subtitle of that unauthorized biography, “How my family created the most dangerous man in the world,” apparently in an attempt to interfere with his re-election.

She refers to the president’s father, Fred Trump, as a “sociopath” who pushed his children to “succeed at all costs,” to see people as “expendable,” and to “do anything to get attention, financial rewards, and to win”

The White House referred to the book as one full of “falsehoods” and “absurd allegations,” and that it was written “clearly in the author’s own financial interest,” rather than in the public interest.

“President Trump has been in office for over three years working on behalf of the American people—why speak out now? The President describes the relationship he had with his father as warm and said his father was very good to him. He said his father was loving and not at all hard on him as a child,” added the statement, quoted by Business Insider.
