A former staff member of the Yale Record says that he recalls many of the details of a prank that Dr. Ben Carson wrote about in an autobiography.

The incident has been the subject of media coverage in recent days, after the Wall Street Journal reported on Friday that it found no evidence to support Carson’s claim that he was a victim of a hoax that led him to take a fake psychology test, as he wrote in his 1990 autobiography, Gifted Hands.

In an interview with BuzzFeed News on Monday, Curtis Bakal, an editorial assistant at the satirical Yale Record who says he helped write the fake test, said he was “99% certain the way Carson remembers it is correct.”

“When I read about the story in the Wall Street Journal, I immediately said, to my wife and friend, ‘That was the prank we played at the Record! And Ben Carson was in the class,’” said Bakal, who noted he wasn’t actually present during the taking of the fake test. “We did a mock parody of the Yale Daily News during the exam period in January 1970, and in this parody we had a box that said: ‘So-and-so section of the exam has been lost in a fire. Professor so-and-so is going to give a makeup exam.’”
