Holder is saying he is looking into taking "significant" action against Assange. Looking into....vague, significant action, vague.
But:
Baruch Weiss, a former federal prosecutor who served in the Treasury and Homeland Security departments, asks:
What law did Assange violate? It will surprise many that there is no statute making it illegal to reveal classified information. There are statutes that criminalize the disclosure of very specific types of classified information, such as the identity of a covert operative (think Valerie Plame) or “codes, ciphers or cryptographic systems.” But there is no catch-all law that simply says, “Thou shalt not disclose classified information.”
