I hope the questions asked also include the following:
1. Did you access (fill in the blank)'s passpsort file to determine what information was there that might be of use to that candidate?
2. Did you access (fill in the blank)'s passpsort file to determine what information was there that might be of use to another candidate or another candidate's campaign/
3. Did you access (fill in the blank)'s passpsort file to determine what information was there that might hurt that candidate?
4. Did you access (fill in the blank)'s passpsort file to modify or change any information was there that might hurt that candidate?
I find it interesting that the CEO of a firm whose employees access Obama's passport record is a foreign policy advisor to Obama. Accessing the file may have been done at the Obama campaign's urging so Obama could express his outrage and prevent negative information from that file from actually being leaked to the public.
I wondered too about the TAC CEO being an advisor to Obama. Your second point is something that hadn't dawned on me and it is an intriguing possibility, given Obama's many questionable relationships with highly suspect individuals.
