The WikiLeaks founder's first name is not written in the complaint, but his last name was mentioned again later, regarding possible evasion or avoidance of arrest in the matter. Dwyer later wrote that the charges would "need to remain sealed until Assange is arrested".
"That was not the intended name for this filing", he told The Washington Post.
The Justice Department is also feeling "increasingly optimistic" about the possibility of having Assange extradited to the United States, the Washington insiders believe, especially because of the growing rift between Assange and Ecuador's leadership.
Julian Assange speaks to the media from the balcony of the Ecuadorian Embassy in London past year. After all, the Obama DOJ concluded, such a prosecution would pose a severe threat to press freedom because there would be no way to prosecute Assange for publishing classified documents without also prosecuting the New York Times, the Washington Post, the Guardian and others for doing exactly the same thing. Throughout that time, the United States has refused to say whether there are any sealed charges against Assange.

Prosecuting someone for publishing truthful information would set a bad and unsafe precedent. Assange and his supporters have periodically said US authorities had filed secret criminal charges against him, an assertion against which some USA officials pushed back until recently.
In the years since, the Swedish case has been closed, but Assange has said he can not risk leaving the embassy because the US would attempt to have him arrested and extradited for disclosures of USA government secrets.
Any criminal charge is sure to further complicate the already tense relationship. Officials have also imposed a series of other restrictions on Assange's activities and visitors and - notably - ordered him to clean up after his cat.
WikiLeaks has attracted US attention since 2010, when it published thousands of military and State Department documents from Army Pvt. Assange's defence team subsequently sued Ecuador over the conditions of his stay in the embassy, which, according to them, violate the WikiLeaks founder's rights.
WikiLeaks said on Twitter that it was an apparent "cut and paste" mistake.
