I figured some expenses were hiding, but hadn&#x27;t found enough of them yet.<p>I&#x27;m cobbling together some more data points here. They aren&#x27;t all for the same year, but are close to recent.<p><pre><code>  - Veterans Affairs: ~160B [0]
  - DHS: ~65B [1]
  - &quot;non-military intelligence spending&quot; (I assume including a solid chunk of NSA and CIA): ~55B [2]
  - FBI: ~8B [3]
  - retirement from Treasury (for service before 1984. The reference is interesting!) ~8B [4]

This tallies up to an additional $296B or 8% (for 25% total).<p>The Project On Government Oversight has a similar table [5] that includes some of my items, some additional items, and excludes some of mine. It reaches a $1 trillion &quot;National Security&quot; budget, which shakes out to about 28% of spending.<p>Thanks for the linking and push to keep digging! The &quot;Military budget and total US federal spending&quot; section of the article linked in the parent was a good jumping off point for me, as well.<p>[0]: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;United_States_Department_of_Veterans_Affairs" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;United_States_Department_of_Ve...</a>
