For all the Trump administration’s talk of saving money and increasing “government efficiency,” the president demanded that huge amounts be appropriated in the Republicans’ recent budget bill to fund his mass-deportation program.

In all, $170 billion was set aside to be spent over the next four years for border and immigration enforcement. This total includes $45 billion to create a sprawling detention system (nearly five times the annual budget for the Bureau of Prisons), $30 billion for ICE operations, $46.6 billion for more border wall construction, and, as if that weren’t enough, a new $10 billion border patrol slush fund.

This level of funding is unprecedented. ICE is now the highest-funded law enforcement agency in the country. And that fact raises a question: What exactly are they going to do with all that money?
