In the 1960s, he was involved in the civil rights movement, first as a member of the Nashville Student Movement and then serving as the first chairman of the Student Nonviolent Coordinating Committee (SNCC). Barry came to national prominence as mayor of the national capital, the first prominent civil rights activist to become chief executive of a major American city. He gave the presidential nomination speech for Jesse Jackson at the 1984 Democratic National Convention. His celebrity was transformed into international notoriety in January 1990, when he was videotaped during a sting operation smoking crack cocaine and was arrested by Federal Bureau of Investigation (FBI) officials on drug charges. The arrest and subsequent trial precluded Barry from seeking re-election, and he served six months in a federal prison. After his release, he was elected to the Council of the District of Columbia in 1992. He was elected again as mayor in 1994, serving from 1995 to 1999.
