Soon after Donald Trump’s former national security adviser Michael Flynn agreed to a plea deal with special counsel Robert Mueller on Dec. 1, Kremlin-linked trolls began ramping up their social-media attacks on the Russia investigation. They tweeted out dozens of articles from Fox News and far-right outlets aimed at undermining the credibility of the FBI, Department of Justice, and the so-called “deep state.” And Putin’s trolls would soon have a new vein of material to exploit.

As Christmas approached, a drumbeat against the FBI grew louder in certain quarters of Congress: GOP Rep. Jim Jordan led the attack, claiming on Fox News that the FBI had conspired against Trump’s 2016 campaign. President Trump himself launched broadsides against FBI Deputy Director Andrew McCabe and “leakin’ James Comey.” And on Dec. 20, Fox News star Sean Hannity tweeted “CONSPIRACY: GOP Lawmakers Says FEDERAL CONSPIRACY to Prevent Trump Presidency.”
