You wanted a source that when the Secretary of the State said "we" she meant the state department?
From the article:
The quote is from a 2006 interview between Clinton and Eli Chmosky of the Jewish Press during her campaign for reelection to the US senate, and was part of a previously un-aired portion.
She wasn't the secretary of state when she said it, and probably had no idea that she would ever be secretary of state. I'm not sure why you would think the "we" is the state department.
Additionally there's no context around this quote so it's a pretty significant leap to infer that "Hillary casually said we should have rigged a foreign election". Her next sentence could have very well have been "But we didn't, and we never will because that isn't how we operate". Or it could have been "We actually did try, but we failed because we ran out of funding". Or "That's what I'm hearing from the leaders of Fatah anyway".
Hillary is a pretty big POS and it's pretty easy to find shit she did that is horrible but this quote doesn't match up with what you're trying to show.
