Justice Department reportedly preparing to prosecute WikiLeaks founder Julian Assange

After a year of discussions, Justice Department officials are optimistic they will be able to get WikiLeaks founder Julian Assange into a U.S. courtroom, people familiar with the matter told The Wall Street Journal on Thursday.

In 2012, Assange received political asylum from Ecuador, and he has been living in the country's London embassy ever since. Prosecutors do not yet know what charges they might file, but it could involve the Espionage Act, the Journal reports. Prosecutors are also reportedly considering publicly indicting Assange so the Ecuadorian government could see evidence against him and would have a reason to remove him from the embassy.

Last month, Assange sued Ecuador over his conditions in the embassy, and after a judge rejected his claims, he said he believes he'll soon be kicked out. In 2010, Chelsea Manning gave WikiLeaks documents related to the Iraq War, and ahead of the 2016 presidential election, WikiLeaks released thousands of emails hacked from Democrats; Special Counsel Robert Mueller says those hacked emails were provided by Russian intelligence officers.
