The Sunlight Foundation says Missouri Rep. John McCaherty's campaign is auctioning a .223 caliber AR-15 semi-automatic "assault" rifle Aug. 27 to raise money.
Tickets cost $25, and 200 are available, according to a handbill for the event posted by the foundation. Click here for a link to McCaherty's website announcing the auction.
The handbill says the weapon is "Missouri Made," and suggests production by a company called CMMG Inc. Suspected Aurora, Co. killer James Holmes used a .223 AR-15 according to reports.
The Sunlight Foundation is a government watchdog group. It maintains a database of congressional fundraisers called Party Time.
