The 4 December 2015 edition of CBS Evening News set aside a full report to specifically targeting the AR-15. Scott Pelley and Dean Reynolds emphasized that the San Bernandino terrorist attack was the latest mass shooting where the semi-automatic rifle was used. Reynolds pointed out that "there was once a nationwide ban on such assault weapons imposed in 1994...When it was lifted 10 years later, gun rights advocates cheered, and sales rose. But the slaughter at San Bernardino and several other recent mass killings all shared a common thread: the shooters used an AR-15-style rifle."
