In October 2002, Simcox issued a public call to arms, inviting readers of his newspaper, the
Tombstone Tumbleweed, to join a "Citizens Border Patrol Militia" whose function, Simcox said, would be to "shame the government into doing its job" of controlling the United States's border with Mexico. He founded Civil Homeland Defense, a group which patrolled the border, and within the next two and a half years sought to assist the
United States Border Patrol. Simcox's practice of reporting illegal immigrants attempting to enter the country has been controversial, and questions concerning its legality have been raised. When Civil Homeland Defense was first formed, Simcox's opponents claimed that it is illegal for a normal citizen who is in no way affiliated with law enforcement to detain people in the United States. Simcox claimed at that time that these detentions were justified under a "
citizen's arrest" policy. Since the inception of the MCDC, however, their "Standard Operating Procedure" (SOP) states that "Minutemen Observe, Report, Record, and Direct Border Patrol or other appropriate emergency or law enforcement agencies to suspected Illegal Aliens or Illegal Activities." In December 2004, Simcox teamed with
James Gilchrist to organize the
Minuteman Project, which brought nationwide attention to the southern border. While some have accused the Minuteman members of being
vigilantes, supporters claim that there has never been a case of a member of The Minuteman Project physically harming anyone. Simcox was interviewed for the 2005
independent documentary
Wetback: The Undocumented Documentary. He also appeared in a 2006 documentary by Joseph Matthew and Dan DeVivo called "Crossing Arizona" and a 2007 documentary by Chris Burgard called "Border". He has been featured as a guest on
The Political Cesspool. On April 21, 2006, Simcox sent a message to President
George W. Bush asking him to send
National Guard troops to guard the border or the "Minutemen" would begin construction of a wall along the border, built on private property. Simcox has stated he does not receive a salary from Minutemen, and earns income via honoraria and fees received for speaking engagements. He claims to have sold his life story for a film that will soon go into production. During the period between his departure from the Minutemen and his arrest in 2013, Simcox worked for in
Scottsdale, Arizona. ==Senate campaign==
