News release: “Homeland Security and Governmental Affairs Committee Chairman Joe Lieberman, ID-Conn., and Ranking Member Susan Collins, R-Me., took Department of Homeland Security (DHS) officials to task Wednesday for the Department’s failure to complete a global architecture to detect the smuggling of nuclear materials, despite a five-year effort and the expenditure of $4 billion of taxpayer money. At a hearing entitled Nuclear Terrorism: Strengthening our Domestic Defenses, Part II, the Senators expressed their frustration and disappointment with the work of the Domestic Nuclear Detection Office (DNDO): its failure to develop a strategic plan to guide nuclear detection efforts by DHS agencies and the failure of its two largest acquisition programs – the Advanced Spectroscopic Portal (ASP) and the Cargo Advanced Automated Radiography Systems (CAARS) – that represent a combined investment of $400 million over five years.”
