EO 13961 seems to be part of the COG or Devolution and established what can be called as a "Babysitter" to watch over during the Pause.

The Babysitter is established in the Sec 3 of this EO "Federal Mission Resilience Executive Committee" and consists of such big names as:

Members of the Executive Committee
Secretary of Defense: Christopher Miller

Secretary of Homeland Security: Chad Wolf

Director of National Intelligence: John Ratcliffe

in addition to:

Robert O’Brien

Tony Ornato

Russell Vought

Kevin Droegemeir

So Biden is revoking the Babysitter assigned to watch over him, now that Daddy is back!

Sections revoked:

Jon Herold and Badlands Media are validated heavily by this, good on them.

Any explanation on the reasoning?

WTF!
