Story about how she received bribes for allowing Russia to buy 20% of the USA uranium production. She clearly stated how she wouldn't take foreign donations to her foundation while at state, would ask for a waiver to do it if it came up, and would disclose if it happened. She took the bribe, didn't ask for a waiver, didn't disclose it, and failed to report it on her taxes and had to amend them years later after she was caught. She showed "Intent" in hiding the donations because they were bribes.
Did you link to the right article? I see some bad things for her, but not the stuff you were talking about.
1) The foundation wasn't supposed to accept foreign government donations, she didn't. Though she may have taken donations from people who had connections to foreign companies with significant government ties.
2) The foundation was supposed to publicly disclose all the donations to the foundation, apparently this guy who donated, a Canadian, reported on his tax form that he made a bunch of donations that the foundation didn't publicly disclose. I don't know if this was a mistake, deliberate, or some kind of misunderstanding.
3) During this period Bill Clinton got a $500k fee to speak to a Russian bank.
4) There's nothing I saw there about hers or the foundation's taxes. I have no idea where you got the idea she hid something on her taxes.
All the bad looking stuff is Bill Clinton, who ran the foundation, accepting donations or work from people who had a connection to businesses who might be affected by the State Department.
As for "approving something the State Department wouldn't normally even consider". She was only one of multiple people who had a say on the approval. If anything her fighting it would have been the more unusual action.
I'm not sure why people bring up her email scandal.
Because it's the only scandal, where after a critical investigation, there's evidence that she really did do something wrong.
Her problem is most politicians do everything they can to avoid the appearance of impropriety. The Clintons on the other hand, Bill in particular, don't really seem to care about the appearance because they think they'll be attacked regardless.
So you get stuff like this where Bill Clinton is constantly dealing with a bunch of people he should really be avoiding. I don't think Hillary was biased when it came to doing her job, but it does lead to some fishy optics.
