Hoft is a bit of a drama queen but this may actually be big. Isn’t sigint a CIA function? That would lead credence to your supposition.
No...
More the NSA, but all of the organizations that make up the 'Intelligence Community' have some SIGINT capability, or can tap into those that do. And diplomats, particularly Ambassadors and senior embassy staff, are knee deep in the intelligence game. Remember Samantha Power? The 'Unmasker in Chief'? She was our Ambassador to the UN...
SIGINT is an intel function, not unique to the CIA.
The CIA has a wooden submarine. That may be unique.
Sigint is NSA.... so trump has (actually had) everything and still does. the dems are so stupid.
Trump fired her over all this— but... she is still a state dpt. employee. All good- because she will pay for this behaviour... bigly and criminally.
