WikiLeaks founder Julian Assange to plead guilty to Espionage Act violation

WikiLeaks founder Julian Assange plans to plead guilty to a felony charge of violating the Espionage Act for conspiring to unlawfully obtain and disseminate classified national defense information.

The deal with the U.S. Justice Department will resolve a long-running legal saga that spanned multiple continents and centered on the publication of a trove of classified documents, according to court papers filed late Monday.

Assange is scheduled to appear in the federal court in the Mariana Islands, a U.S. commonwealth in the Western Pacific.

The guilty plea, which must be approved by a judge, brings an abrupt conclusion to a criminal case of international intrigue and to the U.S. government's years-long pursuit of a publisher whose hugely popular secret-sharing website made him a cause célèbre among many press freedom advocates who said he acted as a journalist to expose U.S. military wrongdoing. Investigators, by contrast, have repeatedly asserted that his actions broke laws meant to protect sensitive information and put the country's national security at risk.

He is expected to return to Australia after his plea and sentencing, which is scheduled for Wednesday morning, local time in Saipan, the largest island in the Mariana Islands. The hearing is taking place there because of Assange’s opposition to traveling to the continental U.S. and the court’s proximity to Australia.
