Snowden unlikely to 'man up' in face of Espionage Act, legal adviser says 28 May 2014 An adviser to Edward Snowden said on Wednesday that an unfair legal landscape made it unlikely that the NSA whistleblower would take US secretary of state John Kerry up on his invitation to "man up" and return to the United States. In a television appearance on Wednesday morning, Kerry said that if Snowden were a "patriot", he would return to the United States from Russia to face criminal charges. Snowden was charged last June with three felonies under the 1917 Espionage Act. "This is a man who has betrayed his country," Kerry told CBS News. "He should man up and come back to the US."
