I have 2 family members who are/were special agents for the FBI. Much of their job is harvesting evidence to build cases by spying, which frequently comes more in the form of “spying” in the way we saw in The Sopranos.
The FBI is also the premier counter-espionage organization within the US, so it is tasked with spying on suspected foreign / turned spies.
It is much more than a spy network, but it is exactly that as well.
That claim deserves a source.
We don’t know how much the Trump political officials managed to avoid those onboarding requirements. It has been widely reported that at least some of them bypassed eligibility requirements and polygraph. It’s probably not a huge leap to assume these same people were not required to consent to these forever-after-searches.
Also, they do head up the main counterintelligence effort of the US.
How the mighty have fallen.
