[Ed. – Kimberley Strassel is right: this would be beyond appalling. It makes Watergate look like an adolescent caper.]
Thanks to the Washington Post’s unnamed law-enforcement leakers, we know Mr. Nunes’s request deals with a “top secret intelligence source” of the FBI and CIA, who is a U.S. citizen and who was involved in the Russia collusion probe. When government agencies refer to sources, they mean people who appear to be average citizens but use their profession or contacts to spy for the agency. Ergo, we might take this to mean that the FBI secretly had a person on the payroll who used his or her non-FBI credentials to interact in some capacity with the Trump campaign.
This would amount to spying, and it is hugely disconcerting. It would also be a major escalation from the electronic surveillance we already knew about, which was bad enough. Obama political appointees rampantly “unmasked” Trump campaign officials to monitor their conversations, while the FBI played dirty with its surveillance warrant against Carter Page, failing to tell the Foreign Intelligence Surveillance Court that its supporting information came from the Hillary Clinton campaign. Now we find it may have also been rolling out human intelligence, John Le Carré style, to infiltrate the Trump campaign.
