Dirk Kempthorne, a long-serving public official who served as mayor of Boise, U.S. Senator, Governor of Idaho, and Secretary of the Interior, has died at the age of 74.

A Life of Public Service

Kempthorne’s family announced his death on Saturday, stating he passed away Friday evening in Boise. He had been battling colon cancer since last year, though the family did not disclose a specific cause of death.

Early Career and Mayoral Success

Kempthorne began his career in public service with his election as mayor of Boise in 1985, at the age of 34. He served for seven years, successfully negotiating an agreement to construct a convention center that revitalized the city’s downtown area.

From Senate to Governorship

In 1992, Kempthorne won a U.S. Senate seat following the departure of Senator Steve Symms. He was known for his bipartisan collaboration, authoring legislation that ended unfunded federal mandates on state and local governments, which was signed into law by President Bill Clinton.

Instead of seeking reelection to the Senate in 1998, he ran for and won the governorship of Idaho in a landslide victory, receiving over two-thirds of the vote. As governor, he focused on strengthening public education, supporting children and families, and investing in the state’s transportation infrastructure.

Secretary of the Interior

President George W. Bush appointed Kempthorne as Secretary of the Interior in 2006, a position he held until the end of Bush’s presidency. He notably resided on a houseboat on the Potomac River during his tenure.

While facing criticism from some environmental groups, Kempthorne also demonstrated a commitment to environmental protection, notably advocating for the listing of the polar bear as a threatened species under the Endangered Species Act in 2008, even offering to resign if his position wasn’t supported.

Recent Humanitarian Efforts and Legacy

Beyond his official roles, Kempthorne recently assisted with the evacuation of nearly 400 U.S. citizens and Afghan allies from Afghanistan following the U.S. military withdrawal. He described a powerful experience during this effort, involving prayer and a vision that aided in the evacuation.

Former President George W. Bush described Kempthorne as one of the finest public servants he had ever known, praising his character and dedication to preserving natural resources. Idaho Governor Brad Little also lauded Kempthorne’s lasting impact on the state, particularly in education and infrastructure.
