Copied and pasted from Axios--ICE USD 2 B in debt.

The agency charged with carrying out President Trump's mass deportation promises has warned Congress it is short a whopping $2 billion for this fiscal year, Axios has learned.

Why it matters: Immigration and Customs Enforcement (ICE) repeatedly has faced significant budget shortfalls in recent years. Trump's immigration plans — which include deporting "millions" of unauthorized immigrants — would rack up costs even more.

Congress would send ICE an extra $500 million in the stop-gap spending bill that passed the House and is being debated in the Senate.

But that wouldn't come close to covering the nearly $2 billion the agency told Congress it needs just to keep up the work it's doing through the end of September, two sources familiar with the communications told Axios.

Add to that the expense of fully implementing Trump's plans —which will include hiring hundreds of people, more than doubling ICE detention space to 100,000 beds and adding many more planes for deportation flights.

Zoom in: Not all of that is addressed in the bill now before Congress, which means the additional money ICE says it needs is unlikely to land anytime soon.

The Department of Homeland Security may have to pull money from its other agencies — such as FEMA or the Coast Guard — and direct it to ICE.

A report from the Government Accountability Office on budgets from 2014 to 2023 found that ICE regularly overspent and had to grab funds from other agencies within DHS to cover its costs.
