President Donald Trump's niece, Mary Trump said she has heard her uncle use racial and anti-Semitic slurs regularly when growing up. In an interview with MSNBC's Rachel Maddow, Mary Trump promoted her best-selling tell-all book about the president, Too Much and Never Enough: How My Family Created the World's Most Dangerous Man. In the interview, she talked about the language used by her family that she heard when was young and claimed Donald Trump, along with other family members, used racial and anti-Semitic slurs. https://www.youtube.com/watch?v=wZ0VJLhFHMA Maddow asked if Mary Trump heard the president use the n-word "specifically." "Of course I did," Mary Trump responded. "And I don't think that should surprise anybody given how virulently racist he is today," Trump added. Maddow pressed if Trump used anti-Semitic slurs specifically. "Yes," Mary Trump answered. Mary Trump said it was "sort of normal" to hear her family use the n-word or anti-Semitic slurs. She said the language was "perfectly commonplace" especially among older generations. "I didn't share their ideas about race and Judaism at all," she said. "But, you know, growing up with that being perfectly normal, you don't think twice about it." A White House spokesperson told MSNBC that Trump's book is "a book of falsehoods, plain and simple. The president doesn't use those words." White House Chief of Staff Mark Meadows told reporters that he has known the president for 3 years and that "not once have I heard anything like that." In a Washington Post interview, Mary Trump, who is gay, also mentioned the issues of homophobia in the family. "Homophobia was never an issue because nobody ever talked about gay people, well, until my grandmother called Elton John" a slur, she said.
