J.K. Rowling made fun of President Trump on Thursday, joking that he may have unintentionally brought peace to the Middle East with his controversial response to the violence in Charlottesville, Va.

"Unbelievable," the British author of the Harry Potter series tweeted. "He actually did bring the Middle East together."

Rowling was referring to a chyron that ran on CNN earlier Thursday with the words "Iran & Israel condemn Trump's comments," attaching a photo to her tweet.

During the 2016 presidential campaign, Trump promised to unite the Middle East and sent senior adviser and son-in-law Jared Kushner to the region in June to restart negotiations on a peace deal between Israel and the Palestines. Kushner plans to return to Israel and the Palestinian Authority as part of his ongoing effort to broker a peace deal, the Washington Examiner reported last week.

Trump has been heavily criticized this week for first refusing to name and shame the Ku Klux Klan, neo-Nazi and white supremacist groups involved in the Unite the Right rally that turned deadly in Charlottesville on Saturday. Heather Heyer, a 32-year-old paralegal, was killed when a car drove into a group protesting the rally.

While denouncing racism as "evil" on Monday, Trump appeared to walk back the statement during a press conference on Tuesday when he said there were "many sides" to blame for the unrest.
