Democratic Sen. Chris Murphy says "sky will not fall" politically for GOP if they vote for "reasonable expansion of background checks."
ALEX ARGER: 10 victims, 10 minutes of silence over the weekend in Boulder remembering those killed in a mass shooting at a local supermarket.
SAM WEAVER: This is a way for people to be able to step outside with their neighbors, to participate without being too close to one another, but to share in the acknowledgment of those who have passed.
ALEX ARGER: In Colorado, a call to action. A "Denver Post" editorial said the estimated 350 million guns in America is too many. 1700 miles away from Boulder in Washington, DC, a debate.
PAT TOOMEY: No, I don't think the answer is to many guns, Chuck. If I have four or five guns and I buy two more, did America become a more dangerous place? I don't think so.
ALEX ARGER: One approach would be to start with expanding background checks covering all assaults, not just felonies.
CHRIS MURPHY: I think that the theory of the case is that once we convince Republicans that the sky doesn't fall for you politically when you support a reasonable expansion of something like background checks, you can move on to other interventions.
ALEX ARGER: Two House bills have passed expanding the checks. Chances in the Senate are uncertain, with many on the pro-gun side arguing tougher laws wouldn't necessarily stop people like the suspect charged in Colorado, but would make it harder for law-abiding citizens to protect themselves. Back in Colorado, a funeral for Boulder police officer Eric Talley is scheduled for Tuesday. His sister talked to CBS News.
KIRSTIN BROOKS: He loved being a police officer. He's like, it's not my job that's unsafe, Kirstin. He said, it's people. And he said that-- you know? He said it-- it's not a bad job. He said, there's a lot more good.
ALEX ARGER: For Newsy, I'm Alex Arger.
