What this leaves me wondering now, is does a person with pending charges, sealed or not from the public, have a right to disclosure on these charges? If Assange was to have an attorney inquire on his behalf, would they legally have to disclose to him the charges?

The only way I can see that they do not have a sealed indictment is if this is a psych game they are running on him to make him sweat over something that isn't real. Hoping to wear him down as he continues to sit in his prison aka embassy. The people he has pissed off are not known for their compassion.
