Periscope will stream a live interview between Twitter CEO Jack Dorsey and CIA whistleblower Edward Snowden later today. You can watch the interview live at 5pm Irish time on @PardonSnowden. 

The interview will consist of a mix between questions from Dorsey and social media users. Anyone with any questions is being encouraged to tweet them out with #AskSnowden. 

It's not quite clear why the Twitter CEO is doing the interview, as he's not a journalist. He has, however, put his weight behind a campaign to free Snowden in the past. 

The Pardon Snowden campaign urges users to sign a letter intended for President Obama before he leaves office.
