Have any more recent photos been released?
I don’t think so. The most recent photos are from 2017.
I do not know of any. Also, there have been no interviews with him. No one from the media has met face to face with him in quite some time. There have been no phone interviews, no skype, nothing. The only word from him (supposedly) has been via tweets. There is no evidence that McCain himself is actually the author of these messages.
I think he is already dead. For as long as I known of him, he could never pass a camera without stopping to talk to it. Now we haven’t seen him in many months.
