Michael Flynn Jr. issues another dark prophecy: 'Comey is going down'

Earlier this week, Michael Flynn Jr.—son of US Army Lieutenant General Michael Flynn—mysteriously warned "You're all going down" on Twitter.

On Wednesday, Flynn Jr. issued a more specific prophecy of doom, this time directed at former-FBI director James Comey.

"Comey is going down, and he doesn’t even know it yet. Sad.... #ItsComing[sic]" he posted to Twitter.

The warning came in response to Comey trying to explain that informants are an integral part of the FBI's work.

"Facts matter. The FBI’s use of Confidential Human Sources (the actual term) is tightly regulated and essential to protecting the country," he wrote. "Attacks on the FBI and lying about its work will do lasting damage to our country. How will Republicans explain this to their grandchildren?"

It's worth noting that the FBI does have a long history of abusing its power in the agency's use of informants, from COINTELPRO to more recent investigations into terror cases, where informants appear to have instigated criminal conspiracies unlikely to have come to fruition on their own.

So far, there doesn't appear to be credible evidence that the FBI abused its power in investigating the Trump campaign.
