Nancy Pelosi was sworn in as the Speaker of the House (for the second time) in the 116th Congress last month, after battling members of her own party who initially opposed her bid for the role. Not one to back down from a challenge, she secured enough votes to reclaim the speaker's gavel for the second time. The California Democrat has had a long career and is considered one of the most significant political figures of her generation. In 2007, Pelosi was elected as the first female House Speaker in U.S. history-the only woman to hold that office twice. Loved and vilified on both sides of the aisle, we look at her life and career.
