ASPEN (Colorado): The United States is overhauling procedures to tighten access to top-secret intelligence in a bid to prevent another mega-leak like the one carried out by former spy agency contractor Edward Snowden, senior US officials said on Thursday.
The National Security Agency, which Snowden worked for as a Hawaii-based contractor, said it would lead the effort to isolate intelligence and implement a "two-man rule" for downloading — similar to procedures used to safeguard nuclear weapons.
