Jimmy Wales, the founder of Wikipedia, has called on Barack Obama to rein in the National Security Agency as he described the whistleblower Edward Snowden as a hero" whom history will judge "very favourably". Wales called for a "major re-evaluation" of the NSA, adding that the public "would have never approved this sweeping surveillance program" had it been put to a vote. The revelations, Wales said, had been "incredibly damaging and embarrassing to the US. It makes it very difficult for someone like me to go out, as I do, [to] speak to people in authoritarian countries, and say: 'You shouldn't be spying on activists, you shouldn't be censoring the internet', when we [in the US] are complicit in these acts of extraordinary intrusion into people's personal lives. [Snowden] has exposed what I believe to be criminal wrongdoing, lying to Congress, and certainly [an] affront to the Fourth Amendment. I think that history will judge him very favourably. There is a growing sense of concern in Congress about this, a growing sense in Congress that public is angry about this, that they have been misled and I think we are going to see legislation to change this."
