Google asks for disclosure go-ahead
Google is asking the Obama administration to allow the internet company to disclose more details about the US government's closely guarded demands for emails and other information that people transmit online.
The request was made in a letter to Attorney General Eric Holder and FBI Director Robert Mueller.
Google is trying to debunk media reports that the company has created a way for the National Security Agency to gain access to large amounts of its users' online communications.
The reports surfaced last week after a government contractor leaked confidential documents revealing the NSA has been tapping into computers of Google and many other internet services to retrieve information about foreigners living outside the US
Google insists it has only been co-operating in a very limited way.
