I could see them getting some of it back, but there might really be some 4-D chess going on with this administration. I'm in the middle of a podcast explaining how they're planning on using rescission to not have to spend all of the congressionally approved funds.

Apparently, there's a difference between how Congress allocates funding in a budget and how they approve spending in a continuing resolution. The executive branch can't reallocate budget to other purposes, but they are allowed to not spend all of the approved funds from a CR.

Long story short, they might have passed a bloated CR with the intention of rescissioning a bunch of money into reducing the deficit or buying crypto or whatever.
