The National Rifle Association taunted gun control activist David Hogg and his group’s Saturday protest at its Fairfax, Virginia, headquarters by noting his security. “Today, @davidhogg111 (with armed security) and a bunch of gun-grabbing activists protested our empty HQ,” the gun-rights organization wrote on Twitter on Saturday night. Today, @davidhogg111 (with armed security) and a bunch of gun-grabbing activists protested our empty HQ, and there were some interesting people there. Our social team chatted up the crowd and ended the day with ice cream paid for by @Everytown! Stay tuned for video interviews! pic.twitter.com/kIhcWZ28dJ
