Beginning on the evening following the shooting, NBC Nightly News anchor Lester Holt on June 12, sounded the clarion call for gun control: "Today's terror attack brings national security and the debate over gun control to forefront of the presidential campaigns once again." 

And for the next week, an MRC study shows the broadcast network news programs flooded their shows with statements favoring gun control over gun rights by a ratio of 8 to 1. 

MRC analysts reviewed all 47 gun policy stories (41 full segments, 6 anchor read briefs), plus 10 other stories that mentioned gun policy on the Big Three networks' evening (ABC's World News Tonight, CBS Evening News, NBC Nightly News) and morning show programs (ABC's Good Morning America, CBS This Morning, NBC's Today), beginning with the evening (June 12) after the shooting through Friday evening, June 17.
