"The National Rifle Association of America is made up of four million moms and dads, sons and daughters -- and we were shocked, saddened and heartbroken by the news of the horrific and senseless murders in Newtown. Out of respect for the families, and as a matter of common decency, we have given time for mourning, prayer and a full investigation of the facts before commenting. The NRA is prepared to offer meaningful contributions to help make sure this never happens again," the group said. It plans to hold "a major news conference" on Friday and both their Facebook and Twitter presences are active again.
