Back in May, the US government began to process a bill aimed at reining in the NSA's powers of surveillance -- if Google, Apple and Microsoft are sending group letters, you know it's an important bill. However, it's been left on Capitol Hill, rejected by the Senate. It failed a procedural vote, after senior Republicans said it would affect efforts to defend the country from enemies. It fell short of the 60 votes needed, gathering 58 to 42 votes. It's now unlikely to become law, as Republicans (who made up most of the opposition), will hold a majority in the Senate in the new year.
