Surprising no one, the Biden administration has announced that the armed occupation by troops in DC will be a more or less permanent feature. Don’t forget, this was all caused because Trump was a dictator. The fact that they are there through the end of the year isn’t the scary part.
Here is the exact wording:
If it’s not possible to sustain at the current level with NG personnel, we need to establish the number of NG personnel (DCNG and out-of-state) we can sustain for an extended period – at least through Fall 2021 – and understand additional options for providing DoD support, to include use of reserve personnel, as well as active component. (emphasis added)
This seems to indicate that, at some point, they are planning on shifting to active duty personnel.
