Tony Podesta was almost certainly involved in Hillary’s campaign. He has dirt on the whole DNC.
According to donor records, not much. He did help gather up donations for her campaign, but the total sum of that was only ~$1 million, which may sound like a lot but was far far far down the list when compared to others.

Some I'm sure but maybe not much. This is Tony Podesta, not John, and John left their firm in 1993 according to records. Even John Podesta's leaked e-mails didn't show much interaction between the two except for discussions about food, which brought lots of attention but ultimately seemed to go nowhere.
