Trump's niece, Mary, says his reelection would spell 'the end of American democracy'

• President Donald Trump's niece wrote in her new book that "it would be the end of American Democracy" if her uncle were to be reelected in November.
• Mary Trump's "Too Much and Never Enough: How My Family Created the World's Most Dangerous Man" is set to be published July 14. Some outlets have published excerpts of the book.
• The younger Trump said she turned down an invitation to attend her uncle's election-night party in 2016 because she was rooting for Hillary Clinton to win.

President Donald Trump's niece has offered a stern warning about her uncle four months before the 2020 elections.

Writing in her coming book, 'Too Much and Never Enough: How My Family Created the World's Most Dangerous Man," Mary Trump said that if her uncle were reelected, it "would be the end of American Democracy," according to an advanced copy of the book obtained by the Associated Press.

"Lying, playing the lowest common denominator, cheating and sowing division are all he knows," she wrote, according to the AP.

"By the time this book is published, hundreds of thousands of Americans will have been scarified on the altar of Donald's hubris and willful ignorance," she added.

Mary Trump's book is due to be released by Simon & Schuster on July 14.

She is the daughter of the president's late older brother, Fred Trump Jr., who died in 1981 at the age of 42 of complications from alcoholism.

Mary Trump had a big falling out with her uncle 20 years ago when her grandfather died and she and her brother disagreed with the rest of the Trump family on how his estate was being divided up.

She still got an invite to attend her uncle's election-night party in New York City in 2016, however, she wrote, according to the AP.

She said she turned the invite down because she feared she "wouldn't be able to contain my euphoria when Clinton's victory was announced."

Instead, she stayed home as her uncle defeated Hillary Clinton and was elected the 45th US president, realizing voters "had chosen to turn this country in to a macro version of a malignantly dysfunctional family."

She wasn't the only family member unsupportive of her uncle's bid for president, however, the book reportedly said.

She said her aunt, Maryanne Trump Barry, a retired federal court judge, didn't take his campaign seriously either.

"'He's a clown,' my aunt Maryanne said during one of our regular lunches at the time. 'This will never happen,'" Mary Trump recalled her aunt saying.
