I disagree. At this point no.
He is in a position of influence and this is an official report.
It was his opportunity to change tact. He chose not to. He is not acknowledging anything from the report as being valid. He is trying to undermine it's entirety.
He doesn't WANT to admit it.
He's the grown up and sometimes the adult responsibility is challenge views where appropriate because the evidence has become too overwhelming to ignore.
He's trying to not just ignore but discredit.
Key point: He did not have to put in a public appearance today
