Edward Snowden has been the subject of several high-profile appeals this year, calling on Barack Obama to pardon the National Security Agency whistleblower and allow him to return home to the US. Writers, intelligence experts, film stars and tech tycoons have all joined the chorus. Now the most audacious display of support for Snowden is under way. Messages calling for his pardon are being beamed on to the outside wall of the Newseum, the Washington institution devoted to freedom of speech and the press that stands less than two miles from the White House. Saturday night’s action in Washington comes at a critical time for Snowden, who remains in exile in Russia where he has been granted asylum, having been charged in the US with offences under the Espionage Act.
