In November 2010, Arpaio created an armed illegal immigration operations posse to help his deputies enforce immigration law. Members of the posse included actors Steven Seagal, Lou Ferrigno, and Peter Lupus. Because the Maricopa County Sheriff's Office (MCSO) lost its authority to enforce immigration law (both by losing its 287(g) authority and through the Federal court's order in "Melendres v. Arpaio"), the posse is no longer active. While the MCSO website claimed 3,000 posse members, as of July 29, 2015, the posse had 986 members.
