“5.23 million v. 5.11 million,” Trump’s niece tweeted on Friday evening, alongside a thoughtful emoji.

President Trump’s niece, Mary Trump, taunted her uncle on Twitter by boasting about the huge number of viewers that tuned into her appearance on MSNBC.
“5.23 million v. 5.11 million,” Mary Trump tweeted on Friday night, comparing her MSNBC ratings to the ratings of Trump’s town hall event on Fox News in June, according to the New York Post.
Mary Trump also included the hashtag “#seldomseen” in the tweet, which is a reference to an earlier attack made by the president in which he described her as a “seldom seen niece who knows little about me.”

The president’s niece sat down with MSNBC journalist Rachel Maddow on Thursday to discuss her recently published tell-all book about the president and his family entitled “Too Much and Never Enough: How My Family Created the World’s Most Dangerous Man.”
Since hitting the shelves earlier this week, nearly one million copies of the book have been sold.
In the interview with Maddow, Mary Trump reveals that she heard her uncle use the N-word and anti-Semitic slurs.
“I don’t think that should surprise anybody given how virulently racist he is today,” she said. 
When asked about why she decided to speak out now, Mary Trump responded: “I can’t say there was a last straw because there have been so many straws, but certainly the horrors at the border, the separating of children from their parents, the torture, the kidnapping and the incarceration of them in cages was unthinkable, unbearable.
“When an opportunity presented itself to me to do something, I needed to take a leap,” she added, according to Variety.
The comments prompted the president to launch an angry Twitter rant on Friday, in which he describes Mary Trump as a “seldom seen niece who knows little about me.” He also accused her of saying “untruthful things” about him and his family and claimed his niece “violated her NDA.”

The White House has denied the contents of the book and that the president ever used any racial slurs.
