In a pair of recent decisions, the Supreme Court has made it clear that Americans have a constitutional right to own handguns for self-defense. But the court will nonetheless allow "reasonable regulations" on firearms.

The country appears set, following the mass shootings at a school in Newtown, Conn., to have a debate about what restrictions should be put in place.

Members of Congress have already signaled their intent to introduce gun-control legislation next year, which President Obama has indicated in recent days will be a priority.

As new pieces of information come in about Friday's mass shooting at an elementary school in Newtown, Conn., which left 20 children and six adults dead, we'll post them here.

The day began, just after 10 a.m. ET, with Connecticut State Police Lt. J. Paul Vance telling reporters that most of the emerging evidence is "too difficult to discuss ... I'm not going to lie to you."

Even as authorities struggle to gather real clues in Friday's horrific attack, they're warning that those promoting misinformation about the case are subject to prosecution.

"Misinformation is being posted on social media sites," Connecticut State Police Lt. J. Paul Vance said at a news conference Sunday. "These issues are crimes. They will be investigated, statewide and federally, and prosecution will take place when people perpetrating this information are identified."

Police on Sunday said 20-year-old Adam Lanza was armed with a high-powered rifle, two handguns and hundreds of rounds of ammunition when he forcibly entered a Newtown, Conn., elementary school and proceeded to gun down 20 young students and six faculty members.

The latest information on the tragedy, the worst violence at an elementary school in U.S. history, came ahead of President Obama's arrival in the town where Friday's mass shooting took place. The president met with families of the victims and planned to attend an evening vigil, where he will speak.
