ACLU: Bush exceeded authority with wiretaps

The American Civil Liberties Union on Tuesday said it had filed suit against the National Security Agency, alleging that its warrantless wiretapping program is unconstitutional and that President Bush, in authorizing it, exceeded his constitutional authority.
“President Bush may believe he can authorize spying on Americans without judicial or congressional approval, but this program is illegal, and we intend to put a stop to it,” said ACLU Executive Director Anthony D. Romero.
Shortly after the September 11, 2001, attacks, Bush reportedly authorized the NSA to intercept communications between people inside the United States, including American citizens, and terrorism suspects overseas, without obtaining a warrant.
