FILE - In this image provided by Human Rights Watch, NSA leaker Edward Snowden, center, attends a news conference at Moscow's Sheremetyevo Airport with Sarah Harrison of WikiLeaks, left, Friday, July 12, 2013. The whole time Snowden has been seeking asylum, Harrison has been by his side. She has emerged as a central, if mysterious, figure in the saga that has taken Snowden across the world in an attempt to evade U.S. espionage charges.
