This is the Sundance quote in full. As per the article:

“Grenell’s greatest contribution as DNI was personifying a belief that government, including the intelligence apparatus, works for the people; and as a direct result the intelligence apparatus has a responsibility to provide sunlight upon all aspects of their function that does not impede national security. The way to keep politics out of intelligence matters is to keep as much of their activity as public as possible. Sunlight is the best disinfectant. I hope we see more of Ric Grenell in another capacity soon”.

Grenell kicks Warner in the crotch in this letter.. *warning about hiding IC abuses behind unnecessary security classification. “In no case shall information continue to be maintained as classified or fail to be declassified in order to conceal violations of law or prevent embarrassment to a person, organization or agency
