What James Comey Meant by ‘Fuzz’

In Senate-committee testimony, the former FBI director used a definition with links to NASA

 The “no fuzz” turn of phrase extended beyond NASA, becoming “an intelligence community term,” according to Jim Wright, a progressive blogger who served as a chief warrant officer in the U.S. Navy. As Mr. Wright explained on Facebook. “James Comey is saying that intelligence on this is 100% certain. No fuzz. No ambiguity.”
