Sorry, no link - just now heard it on the teevee. Apparently NPS rangers are being detailed to the Southern border for patrol purposes.
I find myself waiting for the fallout from NPS and others. At the old job some of the multi-agency LE stuff included NPS, and I used to dive with NPS rangers a lot when we used to have to do our annual "get your hours in to keep your dive pay" dives. While these were mostly CA based rangers, I don't think I ever met one that was anywhere to the right of "mid-far left". I'm really interested to see when the pushback starts.
