And much of the nation will pause this morning to observe a moment of silence in honor of the victims of the sandy hook elementary school shooting exactly one week ago today. Abc's linsey davis show us what people in newtown, connecticut, and across the country are doing to pay tribute. Reporter: Here in newtown and beyond, a moment of silence and tolling of bells at 9:30 this morning at houses of worship across the country. Bells will ring 26 times, honoring the memories of 20 children and 6 women murdered 1 week ago at sandy hook elementary school. From the president this morning, response to an online petition for the white house to immediate introduce laws on gun control through congress. I want to take a minute to respond and let you know, we hear you. Reporter: For the first time since the tragedy, we'll hear from the national rifle association this morning, in a news conference that's been billed, qu meaningful contributions to make sure this never happens again. It's a discussion that abc's cynthia McFadden had with new york city mayor, michael bloomberg, on "nightline." You hold themresponsible? I hold you and me responsible. We didn't pay attention to what our legislators were doing. But I don't absolve you or me. All of us. Reporter: This is one of the churches where bells will toll this morning. As we remember the victims today, hundreds of schools across the country have canceled about threats. A reminder how on-edge many of us are in the wake of this tragedy. Paula? Linsey, thank you. Live from newtown, connecticut, this morning.
