The senators behind a bipartisan gun legislation proposal hope to have the framework ready for a vote by next week. The outline has the support of 10 Democrats and 10 Republicans – enough to put it over the line for Senate approval. But the current outline is vague – and no price tags are attached.

Meanwhile, Republicans are pushing for "hardening schools."We talk to experts about what that involves and whether it would prevent shootings. Want to support 1A?
