This private seurity section is named “Checkmate”. One thing is the Bitem team and demsheviks will trust them. And they may possibly or likely be retired LE or MIl, they were described as being very skilled or words to that effect. I assume they will be taking their orders from the NG, not from Bitems’ orcs.
Secret Service are the ones that are paying for them and given it’s for a ‘POTUS-Elect’ they will give the orders.
