JK Rowling mocks Donald Trump's 'massive' signature
'Harry Potter' author JK Rowling mocked US President Donald Trump's 'massive' signature displayed on his Iran sanctions memorandum. The author shared his picture on Twitter along with a screenshot that read, "Large writing means...an arrogant person who needs to exhibit compliments." Rowling said she started believing in graphology, the study of handwriting, after coming across Trump's signature.
