My speculation was he was setting up some kind of listening device system or even something that could be used to harm the new administration in some way. In that bunker underneath the WH that is some kind of secure defcon one kinda place.
Here you go:
PEOC: (#709) Presidential Emergency Operations Center is a bunker-like structure that lies underground, beneath the East Wing of the White House
There was a Q post that was interpreted that the PEOC was made safe and some threatening stuff was found and disabled.
[some threatening stuff was found and disabled]
What haven’t they put OB in the slammer? Or, are they throwing a big net out to catch more fish?
