The Navy on Monday sought to explain why it tweeted WikiLeaks founder Julian Assange’s name, attributing it to an “inadvertent keystroke.”

“This morning, an inadvertent keystroke by an authorized user of the U.S. Navy Office of Information’s Digitial Media Engagement Team caused the trending term ‘Julian Assange’ to be tweeted from the Navy’s official Twitter account,” the Navy tweeted.

“The inadvertent tweet was briefly posted for a few second before it was quickly deleted by the same authorized user. The inadvertent tweet was sent during routine monitoring of trending topics.”

The incident came after Assange’s account briefly disappeared from the social media platform before returning Monday morning. It is unclear why the account briefly disappeared.
