This.
Mueller is attempting to bring down the Trump admin, he is not going to touch Hillary or anyone near her. Just look at who he has hired for a pretty strong hint at what they are doing.
The DOJ needs to appoint a special prosecutor for the emails, Uranium One, etc, and staff it with people that Hillary and company need to be afraid of. If Trump does nothing, eventually Mueller is going to come up with some nonsense charges against people very close to Trump (most likely his son) in order to try to impeach him. Trump needs leverage so Hillary's buddies have something to worry about, along with the fact that these things need investigating anyway.
“Mueller is attempting to bring down the Trump admin,,,,”
Silly me... I thought trying to overthrow the government was illegal?
