Actress Leah Remini left the Church of Scientology in 2013 - after 35 years as a devout member - and ever since, she has been on a crusade to expose the controversial organization's secrets. On Scientology and the Aftermath," her new series on A&E, Remini seeks to "delve deep into shocking stories of abuse, heartbreak and harassment experienced by those who have left the church and spoken publicly about their experiences." Tuesday night's episode had a theme: Disturbing stories about the organization's leader David Miscavige, whom ex-members refer to as "the pope of Scientology," as well as the "undisputed dictator." Remini ... interviewed people about Miscavige's alleged physical abuse against his staff, including Jeff Hawkins, who was the Scientology "marketing guru" for years. He liked the idea of Scientology's anti-war stance and spiritual component, particularly the strong belief about the afterlife. So Hawkins signed a ... contract and started working closely with Miscavige. Then, he says, Miscavige assaulted him several times. During one incident, he explains, Miscavige once started making fun of him in a room full of people; and when Hawkins asked him not to, Miscavige took that as a sign of disrespect and started hitting him in the face. Hawkins says that he, as well as everyone in the room at the time, was too afraid to fight back. Initially, he thought the bad times would pass; but when he realized Miscavige would be running Scientology for a very long time, he left the church.
