Chris Murphy, who is playing a major role in crafting a bipartisan gun reform bill, said that the legislation won't include an assault weapons ban or comprehensive background checks.

Murphy, during an interview on CNN's "State of the Union," told host Jake Tapper that a bipartisan contingent of senators met this weekend, with the group looking at increased mental health funding, additional safety measures for schools, and "modest" gun control regulations as part of a package

He said that a potential Senate bill wouldn't be everything he wanted.

He said that they wouldn't pass comprehensive background checks or ban assault weapons. People in this country want us to move forward. They don't want the status quo to continue for a long time.

Since joining the Senate, Murphy said he has seen some of the most fruitful talks.

He said that he's never been part of negotiations like this. More Republicans are talking about changing gun laws and investing in mental health than at any time since the Sandy Hook Elementary School shooting.

Murphy said that the talks could potentially fall apart.

He said that he's been part of many failed negotiations. I'm not crazy about our chances.
