Representative William D. Delahunt announced Friday that he will not seek re-elction for his eighth term in office.
Delahunt, 68 said the death of Senator Edward M. Kennedy in August has made him realize that he wanted to spend more time with his family, the New York Times reported.
According to the Boston Globe, Delahunt had considered resigning before, but Sen. Kennedy encouraged him to stay two years ago.
The Christian Science Monitor said the retirement of the Democrat will open another opportunity for the Republican party to take another step closer in taking control of the House.
"Life is about change," Delahunt said. "I think it's healthy. It's time."
