LITTLE ROCK, Ark. (AP) — Former U.S. Rep. Robert Marion Berry, an Arkansas Democrat who served seven terms in Congress and was known for his blunt rhetoric and advocacy for farmers and older residents, has died. He was 80.

Berry, who was known as “Marion,” died Friday, his family confirmed in a statement Saturday. A cause of death was not provided.

“With his signature quick wit and way with words, he lived his life in service to others,” said Berry’s son, Mitch. “He truly believed that the role of government was to help people, and it was a charge he took very seriously. He was generous with his time and talents as his dozens of mentees can attest.”

Berry was first elected to Congress in 1996 but decided against reelection in 2010 for health reasons. He underwent surgery to remove a brain tumor in July 2011.

A licensed pharmacist and farmer, Berry was elected to represent the 1st District in eastern Arkansas after serving in President Bill Clinton’s administration as a special assistant for agricultural trade and food assistance. He quickly focused on issues most likely to impact his notably poor district, including agriculture.
