California Democratic Senator Dianne Feinstein has released new statistics showing more than 90 percent of known or suspected terrorists who have attempted to buy a gun since 2004 have passed a background check and been cleared to do so. The data from the Government Accountability Office shows between 2004 and 2015 nearly 2,500 people on the watchlist applied to purchase weapons; nearly 2,300 of them were approved. Last year, individuals on the terrorist watchlist were involved in background checks to purchase firearms 244 times — only 21 of those were denied.
