You wouldn’t think people could forget the name Reality Winner, but with the constant stream of news related to Russian election interference over the past 2½ years, the early chapter involving Winner has been largely forgotten. People could watch Is This a Room thinking it is a fictional, or at least fictionalized, encounter between a young woman and the FBI agents who have come to interrogate her. And that’s the beauty of this show, whose script comes verbatim from an FBI transcript of June 3, 2017, the day Winner—a 25-year-old Air Force veteran who’d been working for a national-security contractor in Georgia—was arrested for leaking classified information to the media.
