CNN To Air Special Edition of AC360

By Chris Ariens 

A 2008 campaign reporting assignment in New Hampshire for Anderson Cooper turned into coverage of a breaking news story related to the Democratic Presidential front runner.

The bomb scare and hostage situation, which was peacefully resolved, prompted CNN to forgo re-airing Campbell Brown‘s documentary, “Campaign Killers: Why Do Negative Ads Work?” for an earlier edition of AC360.

The special airs at 8pmET tonight.
