WASHINGTON (AP) — Leaders of a Senate panel that oversees U.S. intelligence issues said Thursday it has approved a plan to scale back how many American telephone records the National Security Agency can sweep up. But critics of U.S. surveillance programs and privacy rights experts said the bill does little, if anything, to end the daily collection of millions of records that has spurred widespread demands for reform.

Legislation by the Senate Intelligence Committee, which was approved by an 11-4 vote, would increase congressional and judicial oversight of intelligence activities. It also would create 10-year prison sentences for people who access the classified material without authorization, according to a statement released by committee chairwoman Sen. Dianne Feinstein, D-Calif., and Sen. Saxby Chambliss, R-Ga., the panel’s top Republican.
