J.K. Rowling posted a link on her Twitter account that led to a BBC article headlined "Why people are calling American businessman Donald Trump Voldemort."
As a response, numerous social media users started comparing the presidential hopeful with Harry Potter's archenemy, Lord Voldemort.
The author, however, pointed out that her character is "nowhere near" Trump.
On the same social media platform, Rowling blasted the controversial Republican candidate tweeting, "How horrible, Voldemort was nowhere near as bad." She then continued on to describe Trump as a "carnival barker" with "fake hair."
The BBC article discussed Trump's recent call for a "complete and total shutdown of Muslims entering the country" claiming there is a "great hatred towards Americans by large segments of the Muslim population."
His remarks sparked condemnation from both sides of US politics and world leaders, as well. Even the White House challenged Republicans to denounce Trump because of his "unconstitutional" proposals.
White House spokesman Josh Earnest asserted, "What Donald Trump said yesterday disqualifies him from serving as president." He considered Trump's proposals as "offensive" and "toxic."
"What he said is disqualifying and any Republican who's too fearful of the Republican base to admit it has no business serving as president either," Earnest added.
Despite these reactions, Trump seemed to be unfazed. He responded to the outrage in a lengthy interview with ABC America.
He said, "What I'm doing is no different than FDR." Trump referred to the former US president Franklin D. Roosevelt who oversaw the internment of 110,000 Japanese-Americans after the Pearl Harbor Bombing on December 7, 1941.
He emphasized that an attack the scale of the September 11, 2001 incident could happen again if officials do not ban Muslims from entering the country. Trump said, "We have to figure out what's going on."
Trump has yet to respond to Rowling's comment.
