Former FBI Director James Comey on Thursday blasted “weasels and liars” ahead of the likely release of a controversial anti-FBI memo written in part by Rep. Devin Nunes (R-CA), the chairman of the House intelligence committee. “All should appreciate the FBI speaking up. I wish more of our leaders would,” Comey wrote on Twitter. “But take heart: American history shows that, in the long run, weasels and liars never hold the field, so long as good people stand up.” The FBI said this week that it opposes the release of the memo, which Democrats say includes cherry-picked information that paints a false narrative. The document purports to detail surveillance abuses on the part of the FBI, and President Donald Trump is expected to approve its release as soon as Friday.
