I don't find this report to be all that focused on Clinton, actually mentioned very little and more of as a side show. The focus so far as I've gotten in the 800 pages is critical of the red tape in the chain of command and its contribution. 
This I find it amusing that the Bobbies focus on Hillary and the costs as reason to dismiss the report. Much has been brought out and more importantly, the findings are reinforced and laid out for all vs sweeping it under the carpet. 
As to clintons role, it should disturb any reasonable person on either side of the isle that her focus was political first and foremost. It's not what I expect from a Sec of State. 
As to cost, billions are lost in social security and Medicare scams ignored by the current admin. We also have thrown countless millions at failed solar companies etc that make the cost of this report pale in comparison. Co-operation from the demos would have cut the cost immensely and been the right thing to do for all of us.
