President Joe Biden is calling on Congress to tighten gun control measures in the aftermath of two mass shootings in the United States as he considers executive action. In less than a week 18 people have been killed – 10 in Boulder, Colorado, and eight in Atlanta, Georgia – resurrecting calls for gun reform. “I don’t need to wait another minute, let alone an hour, to take commonsense steps that will save the lives in the future,” President Biden said. He urged Congress to ban assault weapons and high-capacity magazines and expand background checks for firearms. “The US Senate — I hope some are listening — should immediately pass the two House-passed bills that close loopholes in the background check system,” he said. “We should also ban assault weapons in the process. “We can ban assault weapons and high-capacity magazines in this country once again.” White House Press Secretary Jen Psaki said President Biden was considering executive action to try and stop gun violence. “We are considering a range of levers, including working through legislation, including executive action,” she said.
