Former Rep. James Mann died Monday, the Associated Press reported Tuesday. The Democrat represented South Carolina in the House from 1969 to 1979 and helped write the articles of impeachment against President Richard Nixon.

Mann, who had Alzheimer’s disease, died in Greenville, his son, James R. Mann Jr., told the AP on Tuesday. He opened a private law practice there after deciding not to seek a sixth term in 1978.

His son said he won dozens of gold medals as a senior Olympian competing in high jump, tennis and horseshoes.

Mann was born in Greenville on April 27, 1920, and graduated from the Citadel in 1941. He served in the Army from 1941 to 1946, then earned his law degree from the University of South Carolina in 1947, according to the Biographical Directory of the United States Congress.

He served in the South Carolina state House from 1949 to 1952.
