17 January 2006 -- Two U.S. civil liberties groups today challenged the legal basis of U.S. President George W. Bush's domestic spying program.
The American Civil Liberties Union (ACLU) and the Center for Constitutional Rights filed suit against the government, saying the program uses unconstitutional methods of intelligence gathering and violates Americans' right to free speech and privacy.
Bush has defended the program, which allows government agencies to monitor electronic communications, as legal and necessary. He says the program is part of national security measures and is aimed at tracking down terrorists.
