If that's the case I'd like to see an email that is sourced, gives proof, etc. I don't know the particulars of that situation but as far as I know you can't just accept money from a foreign government only individuals.
Regardless, it's one thing getting (justifiably?) angry with her for being a shill and it's another thing to call her office, demanding she return the money, and look like a bunch of nuts.
Actually, it's a very good move. These emails get very large circulation, and the well deserved message is going to the email recipent, not hrc.
