NEW YORK -- Bob Costas' "Sunday Night Football" halftime commentary supporting gun control sparked a Fox News Channel debate Monday on whether NBC should fire him and a Twitter storm involving Ted Nugent, Rosie O'Donnell, Herman Cain and many more.

The NBC sportscaster, who frequently delivers commentary at halftime of the weekly NFL showcase, addressed the weekend's murder-suicide involving Kansas City Chiefs linebacker Jovan Belcher. Costas echoed the commentary of another sports writer who wrote that "if Jovan Belcher didn't possess a gun, he and Kasandra Perkins would both be alive today."

There was no immediate comment on Monday from NBC Sports or from Costas.
