Well the first possibility "he didn't tell all he knew" when asked a question, that's seems like splitting hairs on whether or not he lied.
Of course we don't have the transcripts or know the exact instructions to the jury, but this seems kinda weak.
I don't recall reading about any pressure from him on others.
