COLUMBIA, S.C. (AP) — Butler Derrick, who represented South Carolina from the 3rd Congressional District for 20 years and was the last Democrat to hold that spot, has died after a seven-month battle with cancer. He was 77.

Nelson Mullins managing partner Jim Lehman confirmed that Derrick died Monday at his home in Easley.

Derrick was known for his leadership on efforts to establish a regional compact system to spread the disposal of nuclear waste among the states. He was also known for his fight to save the textile industry.

Derrick was the last Democrat to hold the seat. Lindsey Graham won the seat in 1994 after Derrick decided not to seek reelection in 1994.

Funeral arrangements have not been announced.
