WASHINGTON (AP) — Two senators are calling for a national commission to examine mass shootings in the United States, while a colleague says she’s pushing to ban the sale of military-style assault weapons.

The proposals are among the first to come from Congress in the wake of Friday’s school shooting in Newtown, Conn.

Sen. Joe Lieberman, a Connecticut independent, tells “Fox News Sunday” that a national commission could be used to scrutinize the nation’s gun laws, mental health system and the role that violent video games and movies might play in shootings.

Also on Fox, Sen. Dick Durbin, D-Ill., agreed and said it’s time the nation reflected in a “thoughtful way.”

Democratic Sen. Dianne Feinstein of California tells NBC’s “Meet the Press” that she’ll revive her plan to ban new assault weapons.
