Business Insider reported that Publisher’s Weekly announced Clancy’s death on Twitter, and that The New York Times confirmed the report. Clancy, beyond his novels, had co-founded Red Storm Entertainment in 1996, for his video game projects. That company was later sold to Ubisoft.
Clancy, while generally considered conservative in his politics, notably spoke critically about the George W. Bush administration, particularly regarding its handling of terrorism and the investigation of the attacks on 9/11. He was generally considered an expert in the field of espionage writing, and was well-respected by both members of the military and the intelligence community.
