Apparently a US marshall, or even higher level. Something international. i cannot recall. i just wanted to post this clip but couldnt on 4chan, so then I uploaded it after looking for it and realizing it was kinda memory holed as far as "patriot proofs" went, only because there are SO MANY... Starting with the cannons and military rituals on Inaugurations day.

Go back and watch the inauguration, might need archived version if they were altered since then, and watch RIGHT after Biden is inaugurated(sworn in), I believe that is where this scene occurs with Nancy, you can see the woman in other scenes also and maybe see her badge. I will look more on this later, it is interesting. Lmk if you find anything!
