Biden renews call for gun control on Uvalde shooting anniversary.

President Biden marked the first anniversary of the Uvalde school shooting by calling for tighter gun regulations, including a ban on assault weapons. However, he offered no new ideas for how to overcome opposition to such laws in Congress. Biden acknowledged that progress has been difficult, but implored lawmakers to "please do something" to stop the flow of guns involved in mass shootings. The Uvalde shooting, which killed 19 children and two teachers, did little to move lawmakers at the state or national level, and the chances of passing such gun laws anytime soon are slim.
