The agency processed a record 185,345 background checks—roughly two per second—the same day that three people were killed and nine others wounded in an attack at a Planned Parenthood office in Colorado.
The agency received about 5 percent fewer background check requests on Black Friday in 2014, the FBI said.
FBI background checks processed by the National Instant Criminal Background Check System are conducted for gun purchases from federally licensed deals and for permits to carry guns. A background check does not mean a gun was purchased but manufacturers rely on the background check statistics as a measurement of the industry’s health.
The FBI started processing background checks for potential gun owners in 1998 as part of the Brady Handgun Violence Prevention Act.
The previous record for the most background checks in a single day was Dec. 21, 2012, about a week after 20 children and six adults were shot to death in a Connecticut elementary school. The week following the massacre at Sandy Hook Elementary saw the processing of 953,613 gun background checks.
After the Colorado shootings, President Barack Obama once again called for stricter limits on the availability of guns.
“Enough is enough,” Obama said in a statement on Saturday. He said the Planned Parenthood shootings showed the need to “to do something about the easy accessibility of weapons of war” for “people who have no business wielding them.”
Robert Lewis Dear, 57, is accused of killing a local police officer and two others in the shooting rampage. He is expected to be formally charged later this month.
Law enforcement officials have not disclosed details about multiple weapons found after Dear’s arrest.
