The incoming administration said it would not rely on outside groups to carry out its plan to deport millions of immigrants, but militias have a long record of inserting themselves into patrolling the border.
A few days after the election, William Teer, who runs the Texas Three Percenters, a local far-right militia group, wrote to President-elect Donald J. Trump with an offer: His organization could help Mr. Trump carry out his plan to deport millions of people who are in the United States illegally.
“In support of our nation’s commitments to lawful immigration practices, I wanted to extend my willingness to assist, in cooperation with local law enforcement and community programs, to promote the safety and security of our state,” Mr. Teer wrote. “I am available for further discussion.”
He said Mr. Trump had yet to respond. A spokesperson for Mr. Trump’s transition team said the mass deportation plan would use state and federal resources, not private ones. But Mr. Teer’s offer was one of several recent efforts by far-right organizations, including some that have a history of taking it on themselves to patrol the border with Mexico, to insert themselves into the deportation plan.
