Here's a leagcy worth noting (sarc):

John McCain was instrumental in supporting the weaponization of the IRS to target tea party groups.

“why did the IRS, through Lois Lerner, deliver the 1+ million pages of tax filings, to include the entire donor list of Tea Party and patriot groups, through 21 CD-ROMs and not by electronic data transfer. Information that was specifically sent to Eric Holder and the U.S. Department of Justice”?

This is an obvious question which, despite the numerous congressional hearings on the matter, was never asked – nor answered.
