The Hillary Clinton campaign was also using attorney/client privilege to hide the Clinton campaign's direct coordination with certain FBI people. When it came to inventing leaks against Trump & associates, and then coordinating the hand off of the fake Trump/Russia Hoaxes, the Clinton campaign was micromanaging everything from BOTH ENDS. They weren't just getting regular updates from Sussmann & Elias at Perkins Coie, or from Christopher Steele and Glenn Simpson at Fusion GPS. They were in regular communication with their people inside the FBI. Only they were using Perkins Coie lawyers as the go betweens so they could use the attorney/client privilege to shield what they were doing from the outside world.
