Janet Reno
The first female attorney general, Janet Reno served under President Bill Clinton from 1993 to 2001. Her tenure was fraught with controversies, from the siege of the Branch Davidian compund in Waco, Texas, and the antitrust lawsuit against Microsoft to the return of Elián González to Cuba. Despite those heated issues, Reno was the longest-serving Attorney General of the 20th century.
