Lawmakers across the country are looking into steps to ensure another tragedy like the shooting at a Newtown, Conn. elementary school never happens again.
In Colorado, gun control and violence is up for its first debate of the year in the state legislature.
A Senate committee is scheduled Monday to consider the first gun-related bill of the legislative term.
The measure would permit school officials to allow employees to carry concealed weapons. Under current law, an individual with a valid permit may not carry a concealed handgun at any public K-12 school.
Groups opposed to the measure plan to hold a rally outside the Capitol to talk about gun violence and measures to prevent it.
