Most students returned to school in the shattered Connecticut community of Newtown on Tuesday for the first time since a gunman's rampage killed 26 people in an elementary school, reviving the gun control debate in Washington.
Breaking its silence for the first time since the shootings, the powerful gun industry lobby, the National Rifle Association, said it was "shocked, saddened and heartbroken" and was "prepared to offer meaningful contributions" to prevent such massacres.
Businesses also reacted. One retailer, Dick's Sporting Goods, pulled all guns from its store closest to Newtown and suspended the sale of certain semi-automatic rifles in its stores nationwide. A private equity firm said it would sell its investments in a gunmaker after pressure from a major teachers' pension fund.
