In an appearance on NBC's Today Show Friday morning, Lon Snowden, the father of NSA leaker Edward Snowden, said that while he has had no direct contact with his son --- who has been in the transit zone of Moscow's Sheremetyevo Airport since June 23 -- he has contacted him through intermediaries.

While he did not share any details of the intermediaries he is using, Snowden told NBC's Matt Lauer that he is "thankful for anybody at this point that is providing him assistance to keep him safe and secure ... if Wikileaks is doing that, I'm thankful for that."

Snowden appeared with his lawyer, Bruce Fein, and sometimes used vague language when discussing the arrangements. He did not specifically confirm that Wikileaks was helping.
