Watch Live: Marjorie Taylor Greene testifies against challenge to her candidacy

Rep. Marjorie Taylor Greene is testifying in court Friday in an administrative hearing on a challenge seeking to block her from the ballot in Georgia based on a post-Civil War era policy about keeping insurrectionists from office. 

Ron Fein, the attorney for the group of challengers, Free Speech for the People, said Friday that the "most powerful witness against Marjorie Taylor Greene's candidacy, in establishing she crossed a line, is Greene herself." 

Greene's lawyer, James Bopp Jr., said the candidacy challenge "cannot be decided by this court" and suggested that the U.S. House of Representatives should have a role to debate whether she should be disqualified or prevented from being seated as a member of Congress in 2023, after the midterm election.
