The U.S. House on Wednesday weighed whether to end the National Security Agency's authority to collect hundreds of millions of Americans' phone records as the fight pitting privacy rights against the government's efforts to thwart terrorism got a new airing, AP reported. A showdown vote, expected late in the day, marked the first chance for lawmakers to take a stand on the secret surveillance program since former NSA systems analyst Edward Snowden leaked classified documents last month that spelled out the monumental scope of the government's activities. The issue created unusual political coalitions in Washington, with the Obama administration, national security leaders in Congress and the Republican establishment facing off against libertarian-leaning conservatives and some liberal Democrats. With a flurry of letters, statements and tweets, both sides lobbied furiously in the hours prior to the vote in the Republican-controlled House. The director of national intelligence, James Clapper, warned against dismantling a critical intelligence tool. Republican Rep. Justin Amash, chief sponsor of the effort, said it was designed to end the indiscriminate collection of Americans' phone records. His measure, offered as an addition to a $598.3 billion defense spending bill for 2014, would cancel the statutory authority for the NSA program, ending the agency's ability to collect phone records and metadata under the USA Patriot Act unless it identified an individual under investigation. Amash stepped up the pressure on rank-and-file colleagues, looking ahead to meetings with constituents during next month's congressional break. -- SPA 22:28 LOCAL TIME 19:28 GMT تغريد
