He gave the glasses story to Talking Points Memo and Talon News. He even restated it in his Letter responding to the Senate Intel report.
His wife as a source of info is as much uncommented upon as Pincus' (supposedly) is.
His glasses story does sound like a rehearsed alibi--as does much of what Wilson says. When I was listening to his lecture I noticed him using some rhetorical strategies that have been developed by psychologists for application to marketing and sales. I think he is very calculating in scripting what he says.
The idea of his wife as a source of info is interesting.
