Despite growing opposition in some quarters to ending the NSA’s program, a “clean” authorization — one that would enable its continuation without any changes — is unlikely, lawmakers from both parties say. Sen. Ron Wyden (D-Ore.), a leading opponent of the NSA’s program in its current format, said he would be “surprised if there are 60 votes” in the Senate for that. In the House, where there is bipartisan support for reining in surveillance, it’s a longer shot still. “It’s a toxic vote back in your district to reauthorize the Patriot Act, if you don’t get some reforms” with it, said Rep. Thomas Massie (R-Ky.). The House last fall passed the USA Freedom Act, which would have ended the NSA program, but the Senate failed to advance its own version.The House and Senate judiciary committees are working to come up with new bipartisan legislation to be introduced soon.
