President Joe Biden on Saturday signed the bipartisan Safer Communities Act of 2022 into law at a White House ceremony, CNN reports. The new law instituting expanded background checks for gun buyers under age 21, closing a loophole that allowed domestic partners convicted of abuse to obtain weapons, and incentivizing states to create red flag laws, fund school safety and mental health programs, among other provisions, the first ever national firearms control legislation in decades, spurred by horrific slaughter in Buffalo, New York and Uvalde, Texas in May.
