JK Rowling has faced criticism after her vocal opposition to Donald Trump, and has been sent tweets by fans of the President threatening to burn her books.

She's accused one of these fans of "not thinking" after they said they had burned their collection of Harry Potter novels.

The Donald Trump fan wrote: "Just burned all my Harry Potter books after being a fan for 17 years.

"The Philosopher's Stone was one of the first books I EVER read!"

They continued: "I'm upset it has to be that way... you embarrassed me, disgusted me and I will never read your work again".
