The letter is released to CNN on the same day, and publicly published in full. Addressing his decision not to recommend the indictment of Clinton, Comey writes, “At the end of the day, the case itself was not a cliff-hanger; despite all the chest-beating by people no longer in government, there really wasn’t a prosecutable case.”
CNN also reports that over the past several weeks, “Comey has met with groups of former FBI agents as part of his routine visits to field offices around the country. In at least one recent such meeting, according to people familiar with the meeting, former agents were sharply critical of the FBI’s handling of the Clinton probe and particularly the decision to not recommend charges against Clinton. Comey gave the meeting participants a similar answer about the case not being a cliff-hanger.” (CNN, 9/7/2016)
A later CNN article will identify the particularly contentious meeting as taking place in Kansas City. (CNN, 11/2/2016)
In the letter, Comey also defends his decision to release the FBI’s final report on the investigation (with significant redactions). That was a highly unusual move, because that usually only happens after an indictment or conviction. He makes a particular point to defend the timing of the report’s release, as it came out on a Friday afternoon just before the three-day Labor Day weekend.
