"[T]here has been no challenge to the authenticity of the material in question"

I think this is a key point that needs to be hit over and over again, and Naomi LaChance brings it up in a piece at The Intercept about a National Public Radio host leaning on Julian Assange to reveal Wikileaks's source for a load of Democratic National Committee emails.

Assange, as he usually does, handled the pressure with aplomb:

Greene asked again: "Do you know where these emails came from?"

Assange replied: "Yes, I know where they came from. They came from the DNC."

They did come from the DNC, and they do reveal that the allegedly neutral organization was in the tank for Hillary Clinton and did everything in its power to ensure that she, and no other, procured the Democratic Party's 2016 presidential nomination, and there has been "no challenge to the authenticity of the material in question."

But neither the DNC nor the Clinton campaign want to talk -- or want anyone else to talk -- about the material in question.

All Clinton and the DNC want to talk about is Them Russians.

I can't imagine why.
