You're cherry picking those that are playing defense for Trump but that is hardly a consensus opinion. Literally hundreds of federal prosecutors signed a letter saying there was enough evidence to charge Trump. Not surprising since the report does detail Trump literally trying to obstruct the investigation multiple times. Any one of those you would find damming if it were coming from a democrat. Personally I think Mueller needs to answer some questions but I think his decision to follow the policy that a sitting President cannot be charged was a good one. His investigation is the evidence and it's up to congress to do its constitutional duty to look at it and decide what to do with it.
