MSNBC's top host began the segment after it was introduced by Chris Hayes, agreeing with her colleague that it's surprising that more news outlets aren't giving this story more "wall to wall" coverage, given its immense significance. She recapped Assange's various legal struggles up until this point, then accurately described Assange's new Espionage Act charges for publishing secret documents.

"And these new charges are not about stealing classified information or outsmarting computer systems in order to illegally obtain classified information," Maddow said.

"It's not about that. These new charges are trying to prosecute Assange for publishing that stolen, secret material which was obtained by somebody else. And that is a whole different kettle of fish then what he was initially charged with."

"By charging Assange for publishing that stuff that was taken by Manning, by issuing these charges today, the Justice Department has just done something you might have otherwise thought was impossible," Maddow added after explaining the unprecedented nature of this case.
