“They both accused Trump of being a recruit of Vladimir Putin, they were in agreement with Hillary Clinton’s views. “I would say that any rational human being with even minimal history of the US and the CIA would take everything that the CIA says with a huge grain of salt. I would call it a dose of rational scepticism given that how many times in that past the agency has lied and been in error. Replying to Newsnight presenter Emily Maitlis, who continued to press Mr Greenwald on whether the CIA was “partisan”, the former Guardian journalist fired back.
