Some Sandy Hook families were recognized by the President yesterday during a ceremonial bill signing for the Bipartisan Safer Communities Act.  Nicole Hockley and Mark Barden, who each had sons killed nearly 10 years ago, and their families attended the Rose Garden event.  Hockley says she's thankful to those who advocated for Congress to pass the bill that aims to toughen background checks for young gun buyers, keep guns away from more domestic violence offenders, and help states pass laws to take weapons from people judged to be dangerous.  During the ceremony, President Biden noted that nine Sandy Hook families settled a landmark lawsuit against Remington for $73 million, and asked Hockley and Barden to stand, saying they did more to keep all this going than anyone.
