Background checks spiked after Sandy Hook shooting, says FBI director - The Hill
"Director Robert Mueller told a House Appropriations panel on Tuesday that background check requests from licensed gun dealers has risen from an average of 54,000 each day to a current level of 81,000 every day since the Connecticut shooting, which killed 20 children and six adults.
The FBI has added about 200 people to its previously existing staff of 300 employees to ensure the background checks, conducted through the National Instant Criminal Background Check System (NICS), are completed within 3 days, according to Mueller."
