A federal judge laid out a path Wednesday to revive a constitutional challenge to the National Security Agency's domestic telephone records surveillance program, days after a U.S. appeals court ruled that the plaintiffs lacked standing to sue. U.S. District Judge Richard Leon of Washington, D.C., who earlier had called the NSA call records program "almost Orwellian," said plaintiffs could amend their case immediately to include customers of a Verizon unit known to have participated in the program, Verizon Business Network Services.
