Good find!
Thinking of timing here...
What date is on that note from the GSA admin?
When did she write the other note that she couldn’t start proceedings/preparations for transition?
When did she start getting the threats?
Timing is important; if she posted the note you posted and the one about not starting transition proceedings, —then— started getting threats, it means intimidation and obstruction of an official in the carrying out of their duties.
There’s probably a law about that also, along with the foreign connection one you posted.
The Departmental Seal is also in question.
The “allowance” letter has a Seal that isn’t in the official guide book.
