Democratic Senator Chris Murphy said he's hoping for a framework by the end of the week.
Negotiations on Capitol Hill are reaching a critical point, as top Republican and Democratic senators stake out common ground on legislation that could reduce future mass shootings.
"I've failed so many times before in these talks that I"m sober-minded about our chances," Murphy said Tuesday on ABC's"The View.""But normally, as time goes on, after one of these cataclysmic mass shootings, the momentum fades. The opposite seems to be happening this time.
"I don't think that we can stand by and let our politics stop us from finding a compromise," Murphy said."So we're talking about some common-sense changes to our gun laws that will save lives. Some significant funding for mental health." "I think focusing on concerns about mental health and on people with criminal background records is an obvious area where I think we can work together," Cornyn said.
