The USA Freedom Act, a bill that would end the National Security Agency’s practice of collecting troves of call data from telephone companies, passed on a 67 to 32 vote. It would instead mandate a six-month transition to a system in which the data would remain in private hands but could be searched on a case-by-case basis under a court order.

President Obama has said he will sign the bill, which was passed by a wide margin in the House last month but became caught up in a sharp intraparty divide between Senate Republican leaders who sought to preserve the status quo and a small cadre of GOP senators who joined with Democrats in supporting changes to surveillance programs.
