Hillary was terminated from the investigative team from the Watergate investigations by Zeiffman.
Zeifman was asked directly whether he fired her. His answer: “Well, let me put it this way. I terminated her, along with some other staff members who were — we no longer needed, and advised her that I would not — could not recommend her for any further positions.”
Kessler also notes that Clinton failed the D.C. bar exam in that period. She never retook the exam (passing the Arkansas exam instead) and concealed her failure even from her closest friends until her autobiography in 2003.
Zeifman’s specific beef with Clinton is rather obscure. It mostly concerns his dislike of a brief that she wrote under Doar’s direction to advance a position advocated by Rodino — which would have denied Nixon the right to counsel as the committee investigated whether to recommend impeachment.
