Washington (CNN) - A central part of the gun legislation Congress is expected to take up this week is the idea of expanded background checks on gun purchases. But few Americans understand how background checks actually work.
Leaders from both sides of the aisle - and an overwhelming number of Americans in national opinion polls - support expanded background checks before the purchase of guns. But when it comes to specifics, the divide shows.
Meanwhile, some congressional Democrats are pushing not only for expanded background checks, but also for broadening the requirement for records of sale transactions.
