From the Comey memos, a conversation with Reince Priebus:
David Frum writes that the conservatives have built a closed information system (what Julian Sanchez calls "epistemic closure"). Within their little echo chamber, Republicans actually thought that the release of the memos would help Trump. Frum explains how they hurt:
But before the crisis arrives, the habit of relying on false information leads to bad decision-making—like the very bad decision to leak the Comey memos. Those memos have enhanced James Comey’s testimony, and left Trump looking guiltier than ever. The big news in the Comey memos is that Comey directly told Reince Priebus that a federal court had issued a FISA warrant against his national-security adviser. The president presumably knew this—and kept Flynn on the job while pressuring Comey to end the investigation of Flynn. The leak of the Comey memos has succeeded only in more deeply implicating Trump in the gravest espionage scandal of recent decades.
