A Federal judge in San Francisco heard arguments Friday over whether activists can sue to block what they call an un-constitutional “dragnet surveillance” program. The Electronic Frontier Foundation says the program rounds up phone calls, e-mails and internet browsing information on millions of Americans with no warrants or suspicion. The Electronic Frontier Foundation is trying to sue to halt the program. The Federal government says there’s no information the program even exists, and it says a lawsuit to find out is blocked by national security law. Christopher Martinez reports.
