Jay Rockefeller, a descendant of one of America’s best-known and wealthiest families, died on Friday. The politician and businessman passed away at his home in Washington.
His family did not disclose the cause of death, Antena3 reports. Rockefeller was 89 and had served in the U.S. Senate for three decades.
During his terms in office, he advocated expanding access to healthcare for the poor and vehemently criticized President George W. Bush for his handling of the Iraq War, although he had initially supported launching the offensive.
Jay Rockefeller was the great-grandson of oil magnate John D. Rockefeller—the first American billionaire. His family established a political and business dynasty and has been accused of being part of the world’s so-called shadow government.
