Anderson Cooper got into a verbal altercation with a Sun News contributor Wednesday night while reporting live on the horrific shooting in Ottawa, Canada.
Cooper was taking a break from live coverage when journalist Vandon Gene approached him and asked for a photo. Cooper quickly denied the request due to the circumstances, telling Gene to "have a little respect."

"No, I will not take a photo with you on a day where someone was killed," Cooper said firmly. "It seems wildly inappropriate."
