Mary Trump, President Trump's niece, filed a lawsuit against the president and his siblings in New York on Thursday, accusing them of fraud. The lawsuit claims the president, his sister Maryanne Trump Barry, and his late brother Robert Trump "concocted scheme after scheme to cheat on their taxes, swindle their business partners, and jack up rents on their low income tenants." Mary Trump, who spoke out against the president in her book Too Much and Never Enough: How My Family Created the World's Most Dangerous Man, also claims that after the death of her father, Fred Trump Jr., the president and his siblings "fleeced her of tens of millions of dollars" of her inheritance. The White House dismissed the allegations. White House Press Secretary Kayleigh McEnany said Mary Trump had "really discredited herself" by secretly recording her aunt, Maryanne Trump Barry, saying that her brother was a liar with "no principles."
