Feinstein leads Democratic senators in call to renew gun debate, vows legislation Democratic senators flung open the door Sunday for a renewed debate on national gun laws, vowing in the aftermath of the deadly Connecticut school shootings to immediately introduce gun-ban legislation and take the issue to the chamber floor. California Sen. Dianne Feinstein said she will introduce a bill on the first day Congress returns in January to ban the sale of so-called "assault weapons" and high-capacity ammunition clips. "I'm going to introduce it in the Senate, and the same bill will be introduced in the House," Feinstein said on NBC's "Meet the Press." Feinstein, a major supporter of a 10-year ban on assault weapons that expired in 2004, said her renewed effort is to get "weapons of war off the streets." She was joined Sunday by Sens. Dick Durbin, Illinois, and Richard Blumenthal, Connecticut, who vowed to bring the issue to Capitol Hill in the coming weeks. Their promises follow the incident Friday in which a gunman purportedly used semi-automatic weapons inside the Sandy Hook Elementary School in Newtown, Conn., to kill 26 people - including 20 first-graders. Durbin, the Senate Majority Whip, said he will hold a hearing in the next few weeks on the issue. "We need to sit down and have a quiet and calm conversation on the Second Amendment," he told "Fox News Sunday." But he thinks the mass shooting could finally result in more strict laws. "I think what happened might at least lead some to sit down" and talk, he said. Blumenthal said he would not discuss specifics while the nation still grieves but said he intends to talk about gun control on the Senate floor as early as this week. "We need to do something," he said on ABC's "This Week." New York Mayor Michael Bloomberg suggested that gun control should be the top item on President Obama's second-term agenda and called on him to lead the debate. "The president has to lead, tell this country what to do," the Democratic mayor told NBC. Bloomberg -- whose group Mayors Against Illegal Guns is becoming increasingly vocal about the issue -- also dismissed the notion that the National Rifle Association remains powerful enough to defeat tighter regulations. 1 objective was to defeat Barack Obama, and he won comfortable," he said. And it's a myth that the NRA is so powerful that Democrats (who voted for the 2004 ban) lost re-election.
