“20/20” reports on former members of the Church of Scientology, including those who are crusading against it and others who still practice outside the Church. In a new interview, ABC News’ Dan Harris sits down with actress Leah Remini, who describes her fight against the Church, including her goal to have the organization lose its tax exempt status as a religion. The Church claims that the movement against it is a conspiracy led by a handful of people who spread lies for fame and money.
