Colorado Democrats advanced restrictions on ammunition magazines and expanded background checks as hundreds of gun advocates filled the state Capitol during an intense day in the battle over new firearm laws.
The husband of former U.S. Rep. Gabrielle Giffords testified Monday in favor of expanding background checks to include private and online sales. A Senate committee passed the bill on a 3-2 party-line vote.
Giffords, a former Democratic congresswoman from Tucson, Ariz., was wounded in a mass shooting in January 2011 while meeting with constituents.
Car honks blared all day outside as lawmakers discussed seven gun bills. Four have passed on partisan votes, including banning magazines that load more than 15 rounds.
The bills still need votes by the full Senate, which is controlled by Democrats.
