Father of NSA Whistleblower is Concerned About His Son

Edward Snowden is reportedly in Hong Kong

The father of Edward Snowden told ABC News he's concerned for his son since Edward revealed himself to be the source of a series of top secret leaks from the National Security Agency.

Lonnie Snowden, who spoke briefly with ABC News Sunday, said he's still digesting and processing the news reports about his son, who he last saw months ago for dinner. Lonnie Snowden said the two parted that meal with a hug.

Edward Snowden, 29, went from obscurity as an NSA contractor to acontroversial international figure Sunday when The Guardian newspaper published an interview in which Snowden said he was the source of headline-grabbing news stories about the NSA's vast surveillance programs -- from the shadowy agency's penchant for vacuuming up millions of Americans' phone call information to spying on foreigners' internet activity.
