Republican Sen. Jim Inhofe, a conservative firebrand known for his strong support of defense spending and his denial that human activity is responsible for the bulk of climate change, has died. He was 89.

Inhofe, a powerful fixture in Oklahoma politics for over six decades, died Tuesday morning after he had a stroke over the July Fourth holiday, his family said in a statement.

Inhofe, who was elected to a fifth Senate term in 2020, stepped down in early 2023.
