JK Rowling

'Harry Potter' author J.K. Rowling trolled United States President Donald Trump by comparing his 2017 presidential inauguration crowd size to aerial photographs of people gathered to watch the Royal Wedding of Prince Harry and Meghan Markle in London on Saturday. On Saturday, during the highly-anticipated wedding, Rowling tweeted a picture of the Windsor wedding crowd and placed it beside a photo of the crowd at Donald Trump's inauguration in Washington D.C.
