Sources within the Trump Administration claim that the “spirit animal” tweet is a reference to a small meeting that McMaster and select others within the National Security Council held in the days prior to August 11.
At that meeting, attendees reportedly joked about each other’s “spirit animals.” Indeed, as of this writing, I cannot neither confirm nor deny that a prominent member of the NSC is imbued with the soul of a platypus.
Since August 11, Cernovich has offered other information that also points to him having sourcing within the NSC. However, the “spirit animal” tweet reportedly represented a more concerning breach. Yet even so, the breach itself is of less evident concern to McMaster and his supporters than is the fact of its August 11 publication.
