Brisbane, Australia CNN  —  A former US Marine accused of training Chinese military pilots will be extradited to face charges in the United States, Australia’s Attorney General confirmed Monday, dealing a blow to supporters who have mounted a public campaign for his freedom. Daniel Duggan, a naturalized Australian, was arrested in the state of New South Wales in 2022 based on a 2017 US grand jury indictment that accuses him of training Chinese military pilots in violation of a US arms embargo.
