The Seventh Circuit has overturned a "landmark order requiring the government to show defense lawyers foreign-intelligence-related surveillance on how a terrorism investigation developed," Politico's Josh Gerstein reports. Judge Richard Posner reasoned that "'the Foreign Intelligence Surveillance Act is an attempt to strike a balance between the interest in full openness of legal proceedings and the interest in national security, which requires a degree of secrecy concerning the government’s efforts to protect the nation,'" according to Politico's report.
