WASHINGTON (Reuters) - The U.S. National Security Agency director on Tuesday defended the spy agency as acting within legal boundaries, amid a public uproar which has grown from anger over the collection of Americans' phone and email records to outrage over spying on European allies.
General Keith Alexander offered an impassioned defence of the beleaguered intelligence agency, telling the House of Representatives Intelligence Committee that the NSA is focused on preventing attacks on Americans and allies, and operates under strict oversight.
