Donald Trump is very very unhappy with his niece, Mary Trump.
In case you missed it, she published a book earlier this week which was widely referred to as an "explosive tell-all" about the president.
Some of the claims she made in Too Much and Never Enough: How My Family Created the World's Most Dangerous Man include that he paid someone to take the SATs for him, that he made creepy comments about his own niece's breasts, and that he went to see a movie while his brother died alone in hospital. Not a particularly flattering picture.
She also called him a narcissist, saying: "Donald is not simply weak, his ego is a fragile thing that must be bolstered every moment because he knows deep down that he is nothing of what he claims to be."
Mary used her background in psychology to add:
Donald’s pathologies are so complex and his behaviours so often inexplicable that coming up with an accurate and comprehensive diagnosis would require a full battery of psychological and neuropsychological tests that he’ll never sit for.
Strong words. And if you think the president is unbothered, think again.
First his family and the White House took every possible avenue to discredit the book and block it from being published.
Now that's failed, Donald Trump is doing what he does best: lashing out in an incoherent string of furious tweets.
He began by announcing he is the "ultimate member of The Book of the Month Club". Very very weird flex.
We're not sure exactly what he means but he seems to be confused about what a book club actually is... If anyone sees him, please can you let them know they're usually joined by people who read books, not people who have books written about how awful they are.
Anyway, he continued by listing his favourite choice insults for John Bolton (seems he's still salty about the last book) and then moved on to Mary, his "seldom seen niece" who his parents "couldn't stand", and calls her "a mess", which seems pretty tame for the president, to be honest.
He ends on an uncharacteristically philosophical note, which seems to suggest he takes the criticism in his stride (lol).
In fact, if you just take the last two sentences of his diatribe, it sounds like the words of a semi-reasonable human... until you remember he just posted a thread of tweets about how much he hates a relative.
So very presidential.
