US attorney general invokes state secrets privilege in suit Calif. Muslims filed against FBI

LOS ANGELES — U.S. Attorney General Eric Holder has invoked state secrets rules to prevent information from being released in a lawsuit filed by Southern California Muslims who claim the FBI monitored their activities solely because of their religion.

In a legal declaration filed late Monday, Holder makes a rare assertion of the state secrets privilege, arguing that it could cause significant harm to national security if the government is forced to reveal the subjects of a mosque-surveillance operation in 2006 and describe how the monitoring was carried out.
The FBI has said it does not initiate counterterrorism operations based solely on a group’s religion.
