The veteran that Dan Seals imported from Peoria to anonymously smear Congressman (and veteran) Mark Kirk's stellar record on vets has been ID'd as a 9/11 conspiracy supporter, but Seals' campaign sees nothing controversial about this guy, Caleb Davis.
Per the Tribune:
Last June, the Peoria Journal Star reported that Davis wore a black T-shirt proclaiming "Investigate firstname.lastname@example.org" while sitting at a table at a Peoria library where books, fliers and DVDs supporting conspiracy theories about the 9/11 attacks were on display. The organization argues the government's version of the terrorist attacks is fraudulent and offers a "Top 40 Reasons to Doubt the Official Story" and an "Official Coverup Guide."
