In 1992 Californians became the first in the nation to be represented by two female senators with the election of Dianne Feinstein (born 1933) and Barbara Boxer (born 1940). Feinstein was the first female president of the San Francisco Board of Supervisors. After Mayor George Moscone’s assassination, she became San Francisco’s first female mayor. She is the first woman to chair the Senate Rules Committee and the Select Committee on Intelligence. Boxer was the first female president of the Marin County Board of Supervisors. She was elected to the U.S. House of Representatives in 1982. During the Supreme Court confirmation hearings for Clarence Thomas, she led a group to the Senate Judiciary Committee to demand that they take sexual harassment allegations made against Thomas seriously.
