Why was Hillary Rodham fired from the committee investigating Watergate?

From Fox News, Ed Morrissey, February 25, 2014:

Jerry Zeifman, a lifelong Democrat, supervised the work of 27-year-old Hillary Rodham on the [House Judiciary] committee. Hillary got a job working on the investigation at the behest of her former law professor, Burke Marshall, who was also Sen. Ted Kennedy’s chief counsel in the Chappaquiddick affair. When the investigation was over, Zeifman fired Hillary from the committee staff and refused to give her a letter of recommendation – one of only three people who earned that dubious distinction in Zeifman’s 17-year career.

Why?

“Because she was a liar,” Zeifman said in an interview last week. “She was an unethical, dishonest lawyer. She conspired to violate the Constitution, the rules of the House, the rules of the committee and the rules of confidentiality.”

Liars are addicted to lying; they can’t stop.
