Not being able to answer questions because he wasn't apart of certain investigations and not being able to answer because of ongoing investigations seems pretty straight forward. No matter what he was going to say it was always going to be spun. Nothing is going to happen to Comey or HRC and it hasn't anything to do with corruption or the non-existent Deep State. This is pure political theatrics to rile the base and most should know that. What do you actually expect to come from like this regardless of the answers given?
