On November 2nd, a rogue Twitter employee temporarily deactivated the Twitter account belonging to President Donald Trump. After initially reporting that it had been an error, Twitter said that the action had been taken by a contractor on his last day. Now, after a global manhunt by journalists, the former employee revealed himself to TechCrunch. His name is Bahtiyar Duysak, a German citizen of Turkish descent, and he worked for Twitter as a contractor with a firm named Pro Unlimited.

Duysak said the move was “a mistake” and told TechCrunch he never thought the account would actually be deactivated. He attributed the deactivation to a series of unspecified “coincidences” that had occurred on his final day. “I had a wild time in America,” Duysak said. “I was tired sometimes. And everyone can do mistakes. I did a mistake.”
