The Pentagon is recruiting civilian employees to join Donald Trump’s mass deportation campaign and asking staff to sign up for deployments to immigration enforcement facilities across the United States.

The defense department has posted a job listing requesting volunteers for civilian federal employees apply to join a “volunteer force” supporting Immigration and Customs Enforcement (Ice) and Customs and Border Patrol (CBP) operations. On Wednesday, the department reportedly emailed civilian employees asking them to take up this opportunity.

“The Secretary of Defense has authorized DoD civilian employees to participate in details to the Department of Homeland Security to contribute to its operations along the Southern Border and its internal immigration enforcement activities,” reads the email, obtained by 404Media. Roughly 950,000 civilian employees work for the Pentagon.

Selected employees will reportedly “offer critical support” to Ice and border patrol “as they fulfill the President’s intent to ensure a safe and orderly immigration system”.
