That revelation was found in the diary of Clinton family friend and confidante, Diane Blair. She worked on Bill Clinton's two presidential campaigns and advised the president and first lady throughout their eight years in the white house.
Blair's papers and diary were donated to the University of Arkansas after her death in 2000. The now-public documents recount Mrs. Clinton telling Blair she was not worried about future relations with congress during her husband's presidency because she had plans to leave politics and become a teacher.
Instead, as you know, Clinton would go on to serve eight years in the U.S. Senate and four years as Secretary of State.
