The U.S. government is investigating whether the disclosure of a highly classified U.S. surveillance program by Edward Snowden was criminal.
Snowden said Sunday he is the source for news reports of the U.S. National Security Agency's monitoring of phone calls and Internet data for threats of terrorism, a program the Obama administration says keeps America safe from terrorists.
Meanwhile, European officials are examining the spy programs and whether they violated local privacy protections. European governments have been trying to explain whether they let Washington spy on their citizens or benefited from snooping that would be illegal at home
EU officials in Brussels pledged to seek answers from U.S. diplomats at a ministerial meeting later this week in Dublin.
In Washington, lawmakers say they are looking at potential ways to keep the United States safe from terror attacks without giving up privacy protections.
Snowden's whereabouts are unknown since he checked out of a Hong Kong hotel on Monday. He said he will seek asylum in any country that believes in free speech and global privacy.
North and South Korea are making final preparations for two days of rare, high-level government negotiations that begin Wednesday in Seoul.
It is still unclear what representatives the countries will send to the talks, which figure to be the most significant between the two Koreas in years.
The North has backed down from an earlier agreement that would refer to the talks as "ministerial-level." Both sides now say they will send other senior-level government officials who are yet to be identified. The two foes have not held ministerial-level talks since 2007.
South Korean President Park Geun-hye said Tuesday she hopes the talks produce long-lasting peace on the Korean peninsula.
