1/ Biden called on Congress to “immediately pass” legislation that would close loopholes in gun background checks and ban the purchase of assault weapons a day after the mass shooting at a grocery store in Boulder, Colorado, which left 10 dead. “I don’t need to wait another minute, let alone an hour to take common sense steps that will save the lives in the future,” Biden said, adding that background checks “should not be a partisan issue — it is an American issue […] We have to act.” Earlier this month, the House passed a pair of bills aimed at strengthening the nation’s gun laws. One would expand background checks and the other would extend the waiting period for background checks to 10 days from three days. Both bills face opposition in the Senate, where they don’t not currently have the 60 votes needed to advance.

2/ A Colorado judge blocked Boulder’s ban on assault weapons 10 days ago – the gunman used an AR-15 rifle he purchased six days ago. In 2018, following the school shooting in Parkland, Florida, the city of Boulder passed an ordinance banning the possession, transfer or sale of assault weapons, and large-capacity magazines. But on March 12, Boulder County District Judge Andrew Hartman sided with the plaintiffs (the Colorado State Shooting Association and Boulder-based Gunsport of Colorado), ruling that a 2003 state law banned cities and counties from restricting guns that are otherwise legal under federal and state law.
