As Speaker of the House, she is second in the presidential line of succession, immediately after the vice president. As of 2019, Pelosi is in her 17th term as a congresswoman. She represents California's 12th congressional district, which consists of four fifths of the city and county of San Francisco. She initially represented the 5th district (1987-1993), and then, when district boundaries were redrawn after the 1990 Census, the 8th district (1993-2013).
