Apple's Tim Cook Among Tech CEOs on Witness Shortlist in NSA Case

TheStreet (May 22, 2014) Top executives at some of the nation's leading tech companies may be asked to testify in Germany's investigation into the National Security Agency's data-collection activities, according to a report by the Wall Street Journal. The report says German lawmakers may ask Facebook Chief Executive Mark Zuckerberg, Twitter CEO Dick Costolo, Apple CEO Tim Cook, Google Executive Chairman Eric Schmidt and Microsoft General Counsel Brad Smith to appear as witnesses in the case. The executives would not be required to appear as they are U.S. citizens not present in Germany, according to the report, which cites Roderich Kiesewetter, who sits on the investigation committee. Kiesewetter says the committee hopes the executives would still attend and serve as experts if U.S. authorities prevent them from appearing as witnesses. Video provided by TheStreet
