As predicted by Assange and Wikileaks, Assange has been indicted under the Espionage Act. From Caitlin Johnstone at medium.com:

And there it is. WikiLeaks founder Julian Assange has been charged by the Trump administration’s Justice Department with 17 counts of violating the Espionage Act, carrying a maximum sentence of 175 years in prison. Exactly as Assange and his defenders have been warning would happen for nearly a decade.
The indictment, like the one which preceded it last month with Assange’s arrest, is completely fraudulent, as it charges Assange with “crimes” that are indistinguishable from conventional journalistic practices. The charges are based on the same exact evidence which was available to the Obama administration, which as journalist Glenn Greenwald noted last year declined to prosecute Assange citing fear of destroying press freedoms.
Hanna Bloch-Wehba, an associate professor at Drexel University’s Thomas R. Kline School of Law, has called the indictment “a worst-case, nightmare, mayday scenario for First Amendment enthusiasts.” Bloch-Wehba explains that that the indictment’s “theories for liability rest heavily on Assange’s relationship with Manning and his tendency to encourage Manning to continue to bring WikiLeaks material” in a way that “is not readily distinguishable from many reporter-source relationships cultivated over a period of time.”
