Massa was all over the map because he didn't get a specific question about OBAMA, Rahm or who approached him - what they said, etc.
The guy is not experienced with interviews. He just didn't know what was expected from him. He could not go through an entire litany of things that happened for so many months. I know I couldn't.
I agree that Glenn did not ask good enough questions..Not specific enough. Maybe he thought that Massa would just start spilling his guts and that he didn’t have to get a lot of direct questions prepared.
