Author JK Rowling took potshots at US President Donald Trump for making a grammatical error in a tweet while boasting about his writing ability. Trump in a tweet, hailed himself as "best selling" author. "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! (sic)" Trump had tweeted.

Rowling, the author of the wildly popular Harry Potter series, pointed out that Trump should have written "pore over" rather than "pour over". After posting multiple tweets reading 'hahaha' in repetition, Rowling called out Trump's error and gave him an appropriately misspelt title.
