Senate panel cancels vote on NSA bill

At a committee hearing last week to examine the NSA's programs, Feinstein outlined her plans for the bill. 

She said the legislation would tweak — but not end — the NSA’s controversial program to collect records on all U.S. phone calls.

She said the bill would also require that the Senate confirm the NSA director and would instruct the agency to produce annual reports containing statistics on its surveillance activities.

Sens. Ron Wyden (D-Ore.) and Mark Udall (D-Colo.), vocal civil liberties advocates, had been expected to push more aggressive privacy protection proposals as amendments to Feinstein's bill during the markup. 

A coalition of privacy advocates and other organizations sent a letter to Feinstein on Monday, urging her to make the markup open to the public.
