from washington on this high-stakes cat and mouse pursuit? Standing by, abc's chief white house correspondent jonathan karl and pierre thomas who have been reporting on the damage snowden has already done. Pierre? We're learning the situation could not be more serious. A senior official told us terrorist groups are changing the way they communicate because of snowden's leaks. Secretary of state was blunt, he said people may die because of these leaks. There's still are with about how much damage he can still do. He has access to the u.S. Playbook and it risks the effectiveness of billions of dollars of super computers and spying resources. Think of snowden as that person in the office that troubles you when your computer network breaks down. He had access to everything, that's why top officials are so worried. So it's not just a paper trail. It's the technology as well, he has that playbook. Thank you, pierre. Let's go now to abc's chief white house correspondent, jonathan karl on what the president is doing tonight. What we're seeing here at the white house, the white house accusing china of a breach of trust. We heard from jay carney today, using the kind of language we almost never hear them use around here on describe u.S.-Chinese relations, basically accusing china of lying about why snowden was allowed to leave hong kong. We are not buying this was a technical decision by a hong kong official. This was a deliberate choice by the government despite a valid arrest warrant and that decision unquestionably has a negative impact on the u.S.-China relationship. And there's a message here on russia as well. Robert mueller has been in touch with russian officials several times today, urging them to turn snowden over. The message is clearly a simple one. He's a fugitive wanted for a felony. If russia does not turn him over, that will do tj to u.S.-Russian relations as well. Thank you, for that team coverage of those top secret leaks tonight.
