Mary Lea Trump Ph.D. Biography, Who is Mary Lea Trump Ph.D.

Trump worked for one year at the Manhattan Psychiatric Center while working on her PhD research. Trump is a contributor to the book Diagnosis: Schizophrenia, published by Columbia University Press in 2002. She has taught graduate courses in developmental psychology, trauma, and psychopathology. She is the founder and chief executive officer of The Trump Coaching Group, a life coaching company, and has also owned and operated a number of small businesses in the Northeast.

Trump's father died on September 29, 1981 at the age of 42 from a heart attack caused by alcoholism; she was sixteen. He had developed an enlarged heart and had undergone surgical procedures before he finally succumbed to the disease and died alone in Queens Hospital Center in Jamaica Hills. Trump was at school, watching a film in the auditorium with other kids when a school teacher pulled her aside and made her call home. She found out after a series of phone calls that her father had died. Mary was not able to see her father's body despite her request to do so and had to be content with saying her goodbye to a closed coffin at the funeral.

In her book, Trump relates a time when her grandmother Mary Anne MacLeod Trump referred to Elton John as a "faggot", and Trump decided not to come out as gay and tell her that she was going to marry a woman, with whom she would later raise a daughter. She has since divorced, and lives on Long Island, New York, with her daughter.

Politics
Trump supported Hillary Clinton during the 2016 presidential election. On July 15, 2020, she said in an ABC News interview conducted by George Stephanopoulos that Donald Trump should resign as president. Mary said that he is "utterly incapable of leading this country, and it's dangerous to allow him to do so." In a July 22, 2020 interview on The Late Show with Stephen Colbert, when asked for her professional opinions, Mary stated that Donald Trump exhibits sociopathic tendencies but not at a high-functioning level like his father, was institutionally insulated from responsibilities, and is never held accountable for his actions.

Conflicts within the Trump family

When Fred Trump Sr. died in 1999 from Alzheimer's disease, Mary and her brother Fred III contested their grandfather's will. Fred Sr.'s will left the bulk of his estate, in equal shares, to his children. His grandchildren were each left $200,000. When Mary's father predeceased him, Fred Sr.'s lawyers had recommended amending his will, to leave Mary and her brother, Fred III, larger shares than the grandchildren with living parents. They anticipated Fred Sr.'s will would be challenged if it were not amended by descendants who would argue his intent was that each child would eventually leave a portion of his or her share of the estate to his or her own descendants.

Shortly after Fred Sr.'s death, Mary's sister-in-law gave birth to a son with a rare and debilitating medical condition—one that would require a lifetime of very expensive medical care. Fred Sr. had established a foundation that paid the medical expenses of his family. After Mary and Fred III had filed suit against Donald Trump and two of his three living siblings, Mary and Fred III were advised that the medical foundation would no longer pay for their medical expenses. The lawsuit was settled in 2001. The final settlement of the dispute over sharing Fred Sr.'s estate did not award them the share their father would have inherited, if he had been alive when Fred Sr. died. It did restore coverage of their family's medical expenses.

The 2019 Pulitzer Prize in Investigative Reporting was awarded to David Barstow, Susanne Craig and Russ Buettner of The New York Times for "an exhaustive 18-month investigation of Donald Trump's finances that debunked his statements of self-made wealth and revealed a business empire riddled with tax dodges." Mary was reportedly a key source of information for that study, having come into possession of Donald's tax documents during the discovery process in the dispute over her grandfather's estate.

Upon the announcement of Mary's book Too Much and Never Enough in June 2020, her uncle Robert Trump attempted to block its release, stating that she signed a non-disclosure agreement during the 1999 lawsuit.The filing of a temporary restraining order against Mary was dismissed by a New York court for a lack of jurisdiction, and the book was published on July 14, 2020.

Donald Trump's niece, Mary Trump, released a tell-all book about the President and his family earlier this summer.
In the book, Mary reveals that she was a source for a landmark New York Times investigation.
A couple months later, in September, Mary filed a lawsuit against the President and his siblings, claiming they defrauded her out of her share of her grandfather's wealth.

hen Donald Trump moved into the White House, more than a few of his family members stepped into the spotlight alongside him. It seems not a day goes by that the public doesn't hear about a Trump child's exploits, whether it be Ivanka's poorly-timed Instagram posts or Don Jr.'s right-wing pronouncements; even lesser-known figures, like Donald's sister Maryanne Trump Barry, have found themselves under renewed scrutiny.

But until very recently, the President's niece, Mary Trump, had been hardly heard from at all. With the publishing of her book about her uncle—which prompted a legal skirmish and then set sales records on its first day—that's all changed. In recent months, she's continued to make television appearances to speak about Trump, and filed a lawsuit against the President and his siblings in September.

Here, what you should know about Mary Lea Trump.

She's the daughter of Fred Trump Jr., Donald's older brother.
Mary is the eldest grandchild of patriarch Fred Trump Sr., and the daughter of Fred Trump Jr., the second of Fred Sr. and Mary Trump's five children. Fred Trump Jr. died from a heart attack due to complications from alcoholism, at age 42 in 1981. He left behind two children—Mary L. Trump and Fred Trump III, both teenagers at the time—with Linda Lee Clapp, his former wife.

Fred Jr.'s death left enduring scars on the family, including his younger brother, the now-President. Fred Sr. had hoped that Fred Jr. would take over the family business, but Fred Jr. was reticent to do so, preferring to pursue a career as a pilot. "There was a lot of tension between not only the old man but also between him and Donald," one of Fred Jr.'s friends, Annamaria Forcier, told the Washington Post in 2019. "There was a lot of tension because they didn’t want him to be an airline pilot."

Too Much and Never Enough: How My Family Created the World's Most Dangerous Man

In this revelatory, authoritative portrait of Donald J. Trump and the toxic family that made him, Mary L. Trump, a trained clinical psychologist and Donald’s only niece, shines a bright light on the dark history of their family in order to explain how her uncle became the man who now threatens the world’s health, economic security and social fabric.

Mary Trump spent much of her childhood in her grandparents’ large, imposing house in New York, where Donald and his four siblings grew up. She describes a nightmare of traumas, destructive relationships and a tragic combination of neglect and abuse. She explains how specific events and general family patterns created the damaged man who currently occupies the Oval Office, including the strange and harmful relationship between Fred Trump and his two oldest sons, Fred Jr. and Donald.

A first-hand witness, Mary brings an incisive wit and unexpected humour to sometimes grim, often confounding family events. She recounts in unsparing detail everything from her uncle Donald’s place in the family spotlight and Ivana’s penchant for regifting to her grandmother’s frequent injuries and illnesses and the appalling way Donald, Fred Trump’s favourite son, dismissed and derided him when he began to succumb to Alzheimer’s.

Mary Trump has the education, insight and intimate familiarity needed to reveal what makes Donald, and the rest of her clan, tick. She alone can recount this fascinating, unnerving saga, not just because of her insider’s perspective but also because she is the only Trump willing to tell the truth about one of the world’s most powerful and dysfunctional families.
