Federal spending was $6.7T USD. Cutting 1/3 of that? Probably impossible.
That said, 5% might be possible. That would cover half of the interest payments on the federal debt in a year.
It also depends if they're going for one-time or continuing reductions. Obviously the latter is preferable. And cost-shifting to the future doesn't count.
You have to inflation adjust the 2019 numbers to get the comparables for 2025. And not using the CPI (which is aimed at individuals), but using an index based on what the government actually spends the money on :)
