J. K. Rowling just couldn’t resist.
Here’s how Rowling responded:
Trump often refers to himself by his surname, rather than by using the words “me” and “I.”
It’s a habit that Harvard Medical School professor Elsa Ronningstam says people with “an exaggerated view of how great” they are sometimes use to make themselves appear even bigger.
Trump’s tweet and Rowling’s retort did not go unnoticed by other Twitter users, who seized on the posts to also poke fun at the president.
