Contingency plans. They don't think they've been beaten, yet. They're trying to collaborate and come up with counter moves now that their soft coup didn't work out.
Contingency 1: Midterms don't go their way.
If this happens, they don't have many other options. USSS is no doubt aware of that threat.
Contingency 2: Arranging alternate comms. Somehow eluding our ability to eavesdrop on them. Probably go back to old-school methods of codes and couriers to avoid electronic monitoring.
Contingency 3: preparing their Hail Mary wreck-it-all self-destruct plan, if nothing else works.
Contingency 4: Rat lines. They need them. I'm certain Patagonia is going to have a lot of new "Canadian" residents in the next six months.
