This month’s GOP spending bill included a $485 million budget hike for Immigration and Customs Enforcement (ICE). That likely represents a windfall for the many private vendors profiting from the Trump administration’s ongoing immigration crackdown — including the shadowy aviation contractors carrying out ICE’s deportation flights.

ICE uses private air charter companies — in some cases the same as those that ferry professional sports teams across the country — to carry out its deportations at an extremely high cost. The three flights that carried migrants to El Salvador last week, despite a judge ordering the planes to turn back, likely cost the government upward of $8,000 per hour per aircraft.

At the center of this business, as a report this week from the Project on Government Oversight revealed, is a New Mexico firm that has donated hundreds of thousands of dollars to President Donald Trump and GOP super PACs: CSI Aviation. Last year, the company won a $3.6 billion contract for the flights — although its main competitor, CIA-linked Classic Air Charter, says it was cheated out of the award and is challenging the decision in court.
