Trump named Tom Homan to be his border czar, and Homan has been overseeing the mass deportations of aliens, especially those with criminal backgrounds.
The contractors' proposal said deputized private citizens, including military veterans, former law enforcement officials and retired ICE and CBP officers, would be under Homan's command.
White House spokesman Kush Desai said the administration "remains aligned on and committed to a whole-of-government approach to securing our borders, mass deporting criminal illegal migrants, and enforcing our immigration laws."
