Congressmen Collins (ranking member), Gaetz, and Gohmert were among those who used Crime Prevention Research Center research during the mark up of the Universal Background Check bill (that covers background checks on private transfers of guns).
Congressman Doug Collins is using a CPRC analysis on concealed handgun permit holders from about five years ago. At the time, there were only 11 million concealed handgun permit holders. Today, there are over 17.5 million permit holders.
Congressman Matt Gaetz also referenced work of ours which showed how law-abiding concealed handgun permit holders are.
Congressman Louie Gohmert used our work on the errors in the background check system.
