It is more that strange that Hillary Clinton gets paid big speaking fees for speeches that would appear to embarrass her because she doesn't want us to know what she said. As a Presidential candidate, we would hope that everything she said in those speeches was honest, pro-American and inspirational. By hiding what she said, one could logically conclude that those speeches were none of those things.
Many of her speeches were made while she was employed by us as our Secretary of State. In the world of private business, that is called "moonlighting" and it is frowned upon or outright forbidden. You are not allowed to use your day job to gain other employment or revenue. But, as we see over and over, there are the rules for the rest of us and a different set of rules for the Clintons.
