Chapman has speculated that his arrest was due in part to a possible prisoner exchange agreement between the Mexican and American authorities. According to Chapman, the federal agents "sold him out", by trading him in for a convicted Mexican drug lord. Duane, Leland, and Tim had their ankle bracelets removed so they could work. On October 11, 2006, reports surfaced of an open letter dated September 26, 2006, sent on Chapman's behalf by 29 Republican Congressmen to U.S. Secretary of State Condoleezza Rice. The letter stated the authors' opposition to Chapman's extradition and requested that Rice deny Mexico's request for same. Subsequently, on October 20, 2006, lawyers for Chapman said that the Mexican federal court had granted them an order that halted the criminal case against the bounty hunter until further evidence and witness testimony were gathered. A court hearing was held on December 23, 2006. The original hearing was postponed because a report from a lower court was not yet received. The court heard both sides of the story, and then decided to recess. Then court proceedings started on January 16, 2007 and the court had until Tuesday, February 6, 2007 but the deadline was extended.
