The nation's largest gun owners' organization has issued its first remarks since last week's elementary school shooting, saying it is "heartbroken" by the "horrific and senseless murders" and prepared to offer "meaningful contributions" to prevent a repeat. It says it plans a press conference on Friday.

"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," the NRA said in a statement emailed to reporters. "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."
