Hillary Clinton (and the rest of her family) has come under fire in recent days because she's been accepting money from pretty shady sources.
Apparently, the Clintons, through their Clinton Foundation, have been accepting money from nations that our government says "support terrorism," as well as accepting money from nations with abhorrent records' on human rights issues. (Like Saudi Arabia, which beheads people at a rate second only to ISIS, or Qatar which practically enslaves thousands of migrant workers, or any Middle Eastern nation where women are second class citizens.)
In fact, this issue has gotten controversial enough that even liberal talking heads (whose whole job is to spin stuff like this) can't seem to find a way to defend the Clintons! Former Obama White House Press Secretary Robert Gibbs was on NBC with Chuck Todd where he tried and ultimately failed to defend the Clintons shady moral money-making scheme.
Chuck Todd: They put up a list of governments that have given to the Clinton Foundation, and you see a who's-who of countries in the Middle East. Oman, Qatar, Saudi Arabia, U.A.E., Kuwait. These folks -- Robert Gibbs will say this is all do-gooder stuff in places like Africa having to do with health and food or things like this. But, boy the perception of this. Saudi Arabia: they're a lobbyist. In some ways they lobby America for assistance.
Robert Gibbs: I think there is no doubt the appearances are awkward at best. I think they're going to have to do something in the very short term to deal with this in a way that will put it off the table.
I think there are a lot of people that have watched the sort of 'slow roll' of the Hillary Clinton campaign dating back to last year, with a book tour, speeches, that people wondered what she was doing. From a Democratic perspective, things will get better when there is a formal campaign, but there has been a slow roll of headlines for some time.
