NSA reform heats up in the Senate

The debate over reforming the National Security Agency is heating up in the Senate.

After what some see as a loss in the House, pro-reform lawmakers and advocates are hoping for a comeback in the upper chamber, where they are seeking an end to the NSA’s collection of bulk data from phone calls involving people in the United States. Reform advocates are talking to lawmakers about a narrow definition of “selectors” -- the terms intelligence officials can use to search for information in large data sets -- and there have been some signs of support for their position.
