Colorado Congressman Mike Coffman's campaign is calling for a Super PAC run by former Congresswoman Gabby Giffords to pull a controversial ad. The spot released this week is critical of Coffman, accusing him of protecting special interests like the NRA. It features a hypothetical text conversation between a mother and daughter during a school shooting. Coffman says the ad is too close to a real-life situation that unfolded at Bailey's Platte Canyon High School in 2006. He believes it's exploitive and reprehensible.
