The ISRA is calling upon all lawful American firearm owners to stop doing business with AON Corporation and its subsidiaries. This call for a boycott comes after published reports disclosed that AON is bankrolling a fundraiser for the political arm of the nation's most radical gun control organization. Not only is the fundraiser being financed by AON, it is also being held in a posh club atop AON's Chicago headquarters.
The October 4th event, which AON will hold on behalf of the "Brady Campaign Against Gun Violence," will raise money to fund the Brady Campaign's efforts to impose severe restrictions on citizens' 2nd Amendment rights. Such restrictions include bans on civilian ownership of handguns, target rifles, and popular hunting firearms. The Brady organization also seeks to shutter small firearm retailers and prohibit law-abiding citizens from using firearms to protect their homes and their families.
So the BC is trying to raise money for for their PAC. My guess would be to support Emanuel's Mayor Campaign and to try to keep their losses in N. Illinois to a minimum.
