Nancy Pelosi announces end to nearly four decades in Congress

Nancy Pelosi is arguably the most powerful woman in American history. After her election to Congress in 1987, she accumulated more and more power, eventually rising to become Speaker of the House in 2007, the first and only woman to hold that office. Now in her 20th term, Pelosi announced Thursday morning that she will not seek reelection. Susan Page is Washington Bureau chief for USA Today and author of Madam Speaker: Nancy Pelosi and the Lessons of Power. She joined Consider This host Juana Summers to talk about Pelosi's achievements -- and her legacy.
