Then, in August 2019, Mr. Horowitz’s office released still another report, this one dealing with Mr. Comey’s leaking of memos detailing confidential conversations he’d had with President Trump. In addition to highlighting Mr. Comey’s dishonesty toward the FBI agents dispatched to his home to retrieve the memos, the inspector general scored Mr. Comey for setting “a dangerous example” for the bureau. Later Mr. Horowitz testified that he’d recommended Mr. Comey be prosecuted.

How did Mr. Comey respond? By ignoring the larger indictment of his FBI leadership and focusing only on Mr. Horowitz’s finding that they’d unearthed no evidence Mr. Comey had leaked classified information. “I don’t need a public apology from those who defamed me, but a quick message with a ‘sorry we lied about you’ would be nice,” Mr. Comey tweeted.

So another Comey tweet demanding yet another apology is entirely likely. And it points to the low bar Mr. Comey has now set for America’s most prestigious law enforcement agency: Unless the conduct is criminal, anything goes.
