Dec. 10 (UPI) -- The Department of Homeland Security has inked a deal to buy six Boeing 737 planes to deport immigrants.

U.S. Immigration and Customs Enforcement has used charter planes in the past for deportation flights, but this deal will allow it to operate its own fleet.

The money comes from the $170 billion that Congress authorized for Trump's immigration control plans in a spending bill earlier this year, according to the Washington Post.

In late October, DHS announced it had deported nearly 600,000 people this year.
