He wouldn’t be on TV talking about it.
As I said, I am probably wrong. However, if you read his history, he is a “in the limelight” kind of guy, especially when he investigated the Corruption of the Teamsters. The reason I thought he could be the one Sessions was talking about is that he did seem to have a lot of relevant info when he was interviewed. In other words, like he was already involved. But as I said, it is only speculated.
