Up above is a post to an article that OPM has also published an order of succession. There must be something prompting this at this time. Obviously the succession issue has always been and issue, but for some reason it has suddenly become relevant.
This is called “placing Biden” in a box. Until his nominees are successfully voted on in the Senate and sworn in, PDJT’s people will run the “shops”. They can, and will, slow down any changes Pedo Joe wants to make. If the Republicans maintain the Senate then it may take months for Pedo Joe to get his people in place and make the changes. This is also in anticipation that Pedo Joe will fire, on day one, all of PDJT’s secretaries, making it essential to have line of succession spelled out. Pedo Joe could just issue another EO changing PDJT’s EO’s but there will be a lot of major pushback, including potential lawsuits.
