This appears correct. I'm trying to imagine the life experiences that would take a combat veteran willing to risk life and limb for his country and turn him into this.
He might have skeletons. His care in referring only to the report gives me the impression that he is sticking to a path that isn't his own. It's pretty clear that he doesn't want to express any opinion or interpretation that cannot be plainly found in the report.
He has a lot of work in the investigation, and I'm sure he would like to see something practical result from it. Given how politically difficult prosecuting a sitting president seems to be, making sure to do everything exactly by the book seems like a good tactic to avoid making a misstep that discredits the entire investigation.
