Defense attorney Henry Asbill is continuing to press the point: Did Jonnie R. Williams Sr. know personally that the governor knew about some of his communications with Maureen McDonnell?

Did Williams know for certain, for instance, that he knew she had invited him to a Cure by Design fashion show? He did not.

Did he discuss a health leaders industry reception in February 2012 — for which, Williams testified, the first lady had allowed him to put together the list of people to invite — with the governor when the event was being planned?

Williams also concurred that he never showed the governor the videos of his wife promoting Star Scientific in Michigan and California, videos played for the jury on Thursday.

Likewise, Williams on Thursday testified that Maureen McDonnell had asked him to provide the names of officials at the University of Virginia who were holding up studies of Williams’s product. He said she indicated her husband had asked for them, and prosecutors showed e-mails of Williams forwarding along the names. But on Friday, Williams agreed that he had not heard directly from the governor about the topic.

Williams, however, repeated something he had previously said, that Robert F. McDonnell asked him how the studies were going when he phoned to ask for money in February 2012. Asbill noted that Williams had not been shown any phone record that reflected a phone call between the two in the timeframe Williams’ claimed it had taken place.

What about the expensive dinners Williams treated the McDonnells to? Wasn’t it the wine that made those dinners so expensive — wine that had been ordered by Williams? The businessman did not dispute the idea. “Mr. Perito once represented the French wine industry, so I know a little something about wine,” Williams said, referring to Paul Perito, then the chairman of the board of Star Scientific, who he had previously indicated was a prominent attorney.

And would the governor had known if the wine that Williams selected cost $50 or $500? Williams said he would not have allowed the governor to know that.
