Interpol placed Julian Assange on its most-wanted list after Sweden issued an arrest warrant against him as part of a drawn-out rape probe - involving allegations Assange has denied. The Interpol alert is likely to make international travel more difficult for Assange, whose whereabouts are publicly unknown.
While Assange, the founder of WikiLeaks, taunted the U.S. from afar on Tuesday, lawyers from across the government were investigating whether it could prosecute him for espionage, a senior defense official said. The official, not authorized to comment publicly, spoke only on condition of anonymity.
There have been suggestions that Assange or others involved in the leaks could be prosecuted under the Espionage Act, but the question could be complicated. Who and what is he and his website? He has portrayed himself as a crusading journalist, and the Justice Department has steered clear of prosecuting journalists for publishing leaked secrets.
