Former U.S. governor and senator Jay Rockefeller (John D. Rockefeller IV), a member of the Rockefeller dynasty and a Democrat who represented West Virginia for decades, died Thursday night at his Washington home at age 89, according to Seznam Zprávy pickups of AP and Reuters.

Rockefeller came to West Virginia in 1964 as a federal anti-poverty volunteer. He won a seat in the state House of Delegates, served as secretary of state, then as governor from 1977 to 1985, before entering the U.S. Senate in 1985.

In the Senate, where he served until 2015, he championed expanded health coverage for children and coal miners, mine safety and veterans’ benefits. He opposed the Iraq War and remained a central Democratic voice on health and energy policy.

Governor Patrick Morrisey ordered flags in West Virginia lowered to half-staff through 13 November. The Rockefeller family announced his death without giving a public cause.

Across three decades in federal office, Rockefeller chaired committees on commerce and intelligence and used the weight of his name to draw investment into one of America’s poorest states. Critics often cast him as a wealthy outsider; West Virginia voters nonetheless returned him to office repeatedly.

His death closes a long chapter of American politics tied to the Rockefeller dynasty — after uncle Nelson served as vice president and great-grandfather John D. Rockefeller founded Standard Oil. Jay Rockefeller remains one of the longest-serving Senate Democrats of his generation.
