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. It's unclear whether hammering out the details will lead to a drop in Republican support.

For now, the proposal plans to ramp up funding for state red-flag laws, mental health resources, and more school security.

Meanwhile, Republicans are pushing for "hardening schools."

We talk to experts about what that involves and whether it would prevent shootings.
