Joe Biden signs most sweeping gun control law in decades – video

US president Joe Biden on Saturday signed the most sweeping gun violence bill in decades, a bipartisan compromise that seemed unimaginable until a recent series of mass shootings, including the massacre of 19 students and two teachers at a Texas elementary school. While the new law does not include tougher restrictions long championed by Democrats, such as a ban on assault-style weapons and background checks for all gun transactions, it is the most impactful firearms violence measure produced by Congress since enactment of a long-expired assault weapons ban in 1993.
