I'd like a source on Clinton herself calling for Assange's execution.
IMO, it was likely a joke.
Speaking for myself I know I would never say that, so the response would be "No, I never said that."
I would also add that to the American people and to our friends and partners, I want you to know that we are taking aggressive steps to hold responsible those who stole this information.
