I really do think the letter from the Joint Chiefs was to put democraps of the scent of the impending arrests for treason and that Biden will be arrested by inauguration day with Bill, Hillary, Obama, Pelosi, Schumer and co.
Yes and they are all there ready to arrest Biden and the elites, just waiting for the sign to take them all in to custody then military tribunals.
Of course - he needs to say that to keep the Dems fooled in to thinking Trump is leaving office when we all know our pres will have 4 more years.
