John Oliver Interviews NSA Whistleblower Edward Snowden on ‘Last Week Tonight’

John Oliver interviewed National Security Agency (NSA) whistleblower Edward Snowden for the latest episode of Last Week Tonight with John Oliver. As Oliver notes, the information that Snowden helped reveal to the world is incredibly important to the question of whether to reauthorize some controversial portions–for example, Section 215–of The Patriot Act, and yet people are mostly ignorant to what exactly he revealed, why, and what those revelations actually mean.
