From fiscal 2013 through 2018 (the most recent reporting period), the IG
determined that 350 Defense Department officials — most of them in the
military services — retaliated against or sought to intimidate 195
whistleblowers.
In each of those cases, the IG substantiated both the allegation of
wrongdoing and the report of retaliation for having disclosed it. But only
one of the officials who tried to exact retribution on a whistleblower was
fired.
