Homeland Security Secretary Michael Chertoff said his department will activate his department's new domestic satellite surveillance office in stages, starting as soon as possible with traditional scientific and homeland security activities -- such as tracking hurricane damage, monitoring climate change and creating terrain maps.

"I have had a firsthand experience with the trust-me theory of law from this administration," said Harman, citing the 2005 disclosure of the National Security Agency's domestic spying program, which included warrantless eavesdropping on calls and e-mails between people in the United States and overseas. "I won't make the same mistake. . . . I want to see the legal underpinnings for the whole program."

Thompson called DHS's release Thursday of the office's procedures and a civil liberties impact assessment "a good start." But, he said, "We still don't know whether the NAO will pass constitutional muster since no legal framework has been provided."
