Lon Snowden tells ABC's "This Week" he plans to travel to Russia with his attorney to talk to his son about how to fight espionage charges. The two say they haven't spoken directly with the former NSA analyst since he fled the United States and received asylum in Russia.

Lon Snowden says he wants his son to return to the United States at some point. But he says he thinks it's unlikely his son could have a fair trial, given public statements from government officials calling the younger Snowden a traitor.

Edward Snowden has been charged in federal court in Alexandria, Va., with violations of the Espionage Act.
