Before the Senate Committee, I believe Tom was in the dark about Pentangeli. Having Michael read his statement laid a foundation for perjury. Also, Tom didn't know that the Senator (Questat[sp])belonged to Roth. Michael pulled this info from Fredo.

I think Michael's frustration with Tom was evident during his return from Cuba when he yelled, Why can't I get a straight answer from you anymore!" I actually didn't think Tom was being evasive...I guess he wasn't as direct as michael would have wanted.

Turnbull has exceptional recall and amazing analysis and could expand on this. I think he talked about this not too long ago.
