Twenty Democratic senators led by New Yorks Kirsten Gillibrand urged the Justice Department to keep enforcing a federal ban on commercial handgun sales to adults under 21 despite an Office of Legal Counsel finding that the statute violates the Second Amendment. Appeals courts remain split, some treating adulthood as when Second Amendment rights fully vest and others noting 21 as the 1791 contract majority age, while the Supreme Court has not resolved the issue. The group argues this age cohort commits violent crimes at higher rates and lists several mass shootings by 18-to-20-year-olds.
