"I don't know that going from communion to playing war games in which you practice killing people is necessarily an improvement," he said.
"Let's have a genuine national commission, but not just on guns, which is what the left wants to do. Let's look at the totality of what affects young Americans today and let's ask a question about why have we become a society in which so many people have no faith in the future, no belief in themselves, and in which they don't see their fellow Americans as human beings, but they just see them as objects."
Gingrich follows in the footsteps of former Arkansas Governor Mike Huckabee, who said the shooting in Newtown happened because we "removed God from our schools," and televangelist James Dobson who said gay marriage and abortion were at fault.
