Mary Trump stands by the claim she made in her new book that her uncle, President Trump, paid someone to take the SAT exam for him.

In her book, Too Much and Never Enough: How My Family Created the World’s Most Dangerous Man, Trump wrote that someone named Joe Shapiro, whom she describes as a “smart kid with a reputation for being a good test taker,” was paid “well” to take the test, helping Trump get into the Wharton School at the University of Pennsylvania as an undergraduate.
