Is this the entire interview?
Other parts were shown on Nightline
last night. Also, Robin Roberts quoted B-29 indirectly on some points, presumably reflecting unaired parts of the interview.
I watched the interview on GMA this morning, and I think what I saw is the same as what you linked. After that, and commentary by 'legal analysts', they moved on to another story. They didn't say there was more of the interview to come. I didn't watch the rest of the episode.
The 'legal analysts' didn't have a word to say about B-29's apparent misunderstanding of the law.
