After graduating from law school, Egan returned to Georgia and established a law practice in
Atlanta. In 1977, Egan resigned from the House when he was appointed
United States associate attorney general, by President
Jimmy Carter. In 1979, Egan resumed his law practice. In 1988, he ran for a seat in the
Georgia State Senate in a special election, to replace Senator
Paul Coverdell who was appointed to the position of director of the
Peace Corps by President
George H. W. Bush on May 2, 1989. Egan was elected to Coverdell's vacated Senate seat in June, 1989. He served in the Senate, representing District 40 in
Metropolitan Atlanta from 1989 to 2001. Egan's willingness to occasionally support an unpopular cause, driven to do so by his own set of ethics, won the respect of colleagues, Republicans and Democrats alike. He became known as "the conscience of the senate" by his Republican colleagues. After his legislative career ended, Egan, who had retired from active practice with the Atlanta law firm of Sutherland Asbill and Brennan, continued his affiliation with the firm in "as counsel" capacity. In 2001, he was one of the first people appointed to the newly created Metropolitan North Georgia Water Planning District by Governor
Roy Barnes. Egan also served on the board of the
Trust for Public Land. == Death ==
