J.K. Rowling Trolls Donald Trump's Spelling and Grammar with Typo-Riddled Tweet

Harry Potter author J.K. Rowling mocked President Donald Trump on Twitter Sunday with a tweet full of typos. Rowling was responding to an earlier message posted by the president, who called out the New York Times for claiming White House special counsel Don McGahn was cooperating with Robert Mueller's investigation.

Trump said the article was "fake news" and alleged members of the media called him to apologize for the misinformation. He claimed this was a step forward.

Rowling, however, noted Trump did not name anyone who called with an apology in her mocking tweet.

"I do'nt care what Kids at School call me because they are all Disgusting Fake Losers and my Real Friends go to a diffrent Scool you haven't heard of and they think Im the Coolest and Smartest and we go to parties and I don't have to tell you there Names for this to be True," the tweet read.

This is not Rowling's first time pointing fingers at Trump on Twitter. One of her most notable tweets aimed at the president explained he's "nowhere near as bad" as Rowling's fictional villain, Voldemort. She also called him a "giant orange Twitter egg" when he debated with Hillary Clinton before his election.

Rowling previously laughed at Trump's claims he's a skilled writer. In a now-deleted tweet, posted in July, Trump spoke of his books and Twitter strategy, the Huffington Post reported. The tweet included the wrong form of the word "pore."

"After having written many best selling books, and somewhat priding myself on my ability to write, it should be noted that the Fake News constantly likes to pour over my tweets looking for a mistake. I capitalize certain words only for emphasis, not b/c they should be capitalized!"

Rowling issued two tweets in response, filled entirely with "haha," one, which noted the typo.

Trump's ghostwriter Tony Schwartz claimed Trump wrote none of his book, The Art of the Deal. Schwartz acted as "co-author" on the 1987 memoir though he's since spoken about his larger role in the publication.

"Many thanks, Donald Trump, for suggesting I run for President, based on the fact that I wrote 'The Art of the Deal,'" he tweeted after Trump announced his presidency, according to The New Yorker.

Even after working with Trump on the book, Schwartz was not a supporter of his candidacy.

"I feel a deep sense of remorse that I contributed to presenting Trump in a way that brought him wider attention and made him more appealing than he is," he told The New Yorker. "I genuinely believe that if Trump wins and gets the nuclear codes there is an excellent possibility it will lead to the end of civilization."
