LITTLE ROCK, Ark. (AP) — Former Arkansas governor and U.S. Sen. David Pryor, a Democrat who was one of the state’s most beloved political figures and remained active in public service in the state long after he left office, has died. He was 89.

Pryor, who went undercover to investigate nursing homes while a congressman, died Saturday of natural causes in Little Rock surrounded by family, his son Mark Pryor, said. David Pryor was a heart attack and stroke survivor who was also hospitalized in 2020 after testing positive for COVID-19.

“I think he was a great model for public service. He was a great role model for politicians, but just for everyone in how we should treat each other and how we can make Arkansas better,” Mark Pryor, a former two-term Democratic U.S. senator, said.

David Pryor was considered one of the party’s giants in Arkansas, alongside former President Bill Clinton and the late U.S. Sen. Dale Bumpers. He also served in the U.S. House and the Arkansas Legislature, and remained active in public life in recent years, including being appointed to the University of Arkansas’ Board of Trustees in 2009. He also attended the inauguration of Republican Gov. Sarah Huckabee Sanders in January 2023.
