Although he's confident that some form of gun-related legislation will ultimately pass Congress, freshman Sen. Angus King (I-ME) on Monday raised doubts about an assault weapons ban.
King emphasized his desire to place limits on high-capacity magazines and institute mandatory background checks, but suggested that "it's tough to define" what constitutes an assault weapon.
"The biggest issue to me is the size of the magazines. That's sort of the common thread that connects a lot of these massacres," King said on CBS. "The assault weapon ban is a tough one because it's tough to define what an assault weapon is. And if we're just defining it by what it looks like, that doesn't do much for me. I'm much more interested in the functionality and whether that's really a different weapon than my buddy's semi-automatic hunting rifle."
