The Trump administration is proposing one of the biggest changes to U.S. firearm regulations in decades and it's already sparking intense debate.The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) has proposed allowing licensed gun dealers to ship firearms directly to buyers' homes within the same state, provided customers complete online identity verification, pass a background check, observe a seven-day waiting period, and local law enforcement is notified.

The president’s eldest son is a key player in GrabAGun, a company that hopes to dominate the sale of firearms through the mail in the United States.

Trump Jr.-backed GrabAGun could benefit from proposed ATF rule easing online gun sales. Critics cite safety risks while supporters see growth.
