McLEAN, Virginia (AP) - The father of NSA leaker Edward Snowden, frustrated by his inability to reach out directly to his son, has written an open letter to him extolling him for "summoning the American people to confront the growing danger of tyranny."
The letter was written jointly on Tuesday by Mr Lonnie Snowden and his lawyer, Bruce Fein.
It comes a day after Mr Edward Snowden issued a statement through WikiLeaks ripping the Obama administration for leaving him "stateless" and revoking his passport.
Snowden is in Russia and has been seeking asylum in multiple countries.
Snowden's father has expressed concern that WikiLeaks supporters who have been helping his son seek asylum may not have his best interests at heart.
The father has said he'd like his son to return to the US under the right circumstances.
