Newtown, Conn.: 20 children massacred; Senate: 6 votes short

The U.S. Senate failed by six votes this week to pass legislation that would require background checks on all gun buyers. A bipartisan bill would have expanded the requirement for background checks to gun sales over the Internet, to gun shows and to other commercial transactions not now covered. The gun lobby spent $1.5 million in the past three months to defeat the measure, a 61 percent increase over its spending a year ago.
