Today, a number of developments in the NSA surveillance story. First, Edward Snowden says he is still in Hong Kong. He gave an interview to the South China Morning Post and said he plans to fight any attempt to extradite him back to the U.S. for leaking classified documents.
CORNISH: On Capitol Hill, the man who heads the NSA, General Keith Alexander, appeared before a Senate panel. He told lawmakers that surveillance programs have helped to stop dozens of attacks.
BLOCK: And some of the biggest technology companies are asking for permission to divulge how often they turn over data to the government. As NPR's Jim Zarroli reports, companies such as Google and Facebook worry the controversy will harm relations with their customers.
JIM ZARROLI, BYLINE: Companies such as Google are very much caught in the middle of the current debate about government security and privacy. Press reports have said they are required to turn over huge amounts of customer data to government agencies like the NSA, but they're often barred from saying anything publicly about the requests they get. So customers are left to wonder whether someone is looking over their shoulders when they go on sites like Facebook. Sarah Rotman Epps is a senior analyst at Forrester Research.
SARAH ROTMAN EPPS: Google, Facebook, Microsoft and the rest of the companies are at risk of losing customer trust, and I think they're frustrated by their inability to talk directly about these matters with their customers.
ZARROLI: And this is an especially big issue in large, growing overseas markets. One of the surveillance programs at issue, known as PRISM, analyzes data collected by U.S. tech companies from foreign users. Manfred Weber is a member of the European Parliament, which has expressed big concern about the programs.
MANFRED WEBER: We are interested in what is going on. Is there really a checking of all the emails? Is there really a checking of all the Internet traffic? We want to know how it works.
ZARROLI: And this could well affect the bottom line at companies like Google. Weber says U.S. surveillance programs appear to give Americans broader privacy protections than non-Americans. He says European regulators are especially bothered by this, and it could well affect Google's ability to do business in these markets.
Yesterday, Google sent a letter to Attorney General Eric Holder asking for permission to reveal how often it really turns over customer information to the government. Microsoft, Twitter and Facebook quickly echoed the request. These companies say releasing this information will dispel the notion that government investigators are given unlimited access to customer data. Ben Wizner of the ACLU applauds Google's move.
BEN WIZNER: We've seen in the last week how important it can be for the public to learn not just about the existence of surveillance, but about the scope of that surveillance.
ZARROLI: Wizner says when it comes to government surveillance programs, Google has been a big advocate of transparency. But he also says Google and the other companies could be doing more.
WIZNER: It would be nice to see some of these companies going into court and challenging the gag orders that have prevented them from sharing information about national security surveillance.
ZARROLI: But it's also true that these companies have to strike a delicate balance on surveillance issues. They need to show they're willing to cooperate with the government to address legitimate security concerns. They just have to do it without giving their customers the impression that someone's watching them every time they go online. Jim Zarroli, NPR News, New York.
