The FBI says the week following the Newtown, Connecticut, shooting massacre saw the greatest number of background checks for firearms sales and permits to carry guns conducted within a one-week period since 1998.

The FBI says the second highest week was when President Barack Obama announced sweeping plans to curb gun violence.

This new data published by the FBI confirms what many gun dealers around the country have said about sales going up after the deadly shooting that left 27 dead, including 20 children, as gun enthusiasts braced for stricter controls.
