WASHINGTON (CNN) – Following the deadliest mass shooting in U.S. History, federal background checks for gun purchases have surged.
The Federal Bureau of Investigation conducted more than 2.1 million background checks in June 2016. Last June, it conducted 1.5 million.
The FBI conducts a background check every time someone tries to buy a gun from a federally licensed dealer.
Mass shootings appear to drive gun sales. The mass shooting at Sandy Hook Elementary in Newtown, Connecticut, fueled a massive surge in background checks in December 2012.
The San Bernardino Massacre of December 2015 fueled more than 3.3 million background checks that month. There was more than 23 million background checks for the year, that is the current record.
