JK Rowling has once again shown why you should definitely follow her on Twitter.

After claiming her villainous creation Lord Voldemort is “nowhere near as bad” as Donald Trump, Rowling has now turned her attention to the presidential candidate’s campaign team.

Trump’s spokeswoman Katrina Pierson caused a stir on social media recently after a controversial tweet from 2012 went viral.

“President Obama’s dad born in Africa, Mitt Romney’s dad born in Mexico. Any pure breeds left? #CNNDebate’,” Pierson wrote.

Unsurprisingly, the spokeswoman received a huge backlash from fellow Twitter users – however, Rowling’s response put the rest to shame.

“Death Eaters walk among us,” she wrote, simply.

For those who are unfamiliar with the Harry Potter franchise, Death Eaters is the name given to the twisted followers of Lord Voldemort.

They practised the Dark Arts, (torture, murder etc.) and thought anyone who wasn’t “pure-blood” (a witch or wizard with no Muggles in their family) was inferior to them.

Rowling has become known for giving brilliant responses on social media.

Highlights include a recent response to the Westboro Baptist Church (WBC), who took offence to the idea of Rowling’s creation Dumbledore marrying fellow wizard Gandalf.

She has also used Twitter to support her legion of LGBT fans, offering words of wisdom and comforting advice to those struggling with their sexuality.

Trump, meanwhile, has had the highest honour possible in his US Presidential campaign – an endorsement from Sarah Palin.

The former governor of Alaska and staunch opponent of LGBT rights, who was the 2008 vice-presidential candidate, gave a colourful speech supporting Trump during a campaign rally in Iowa last week.
