An attorney for the father of Edward Snowden said Sunday that they have obtained visas to visit Russia, and they will do so soon to discuss Snowden's possible return to the United States to face criminal charges.

"We now have a date for visiting Moscow. We have visas, we have a date which we won't disclose right now because of the frenzy," the attorney, Bruce Fein, said on ABC's "This Week." "It's very soon. And we intend to visit with Edward and suggest criminal defense attorneys who have experience in Espionage Act prosecutions."

Appearing together on the show, Fein and Lon Snowden said they want to make sure that Edward Snowden would face a fair and open trial if he were to return.

"The only deal would be true justice," Lon Snowden said, adding: "My son has spoken the truth. He has sacrificed more than even the president of the United States or Peter King have in their political careers or their lives."

Snowden also was critical of the measures President Obama announced Friday to reform the way the federal government conducts surveillance.

"I believe much of what he suggested is superficial," Snowden said.
