"I joined CNN a week after Gabby Giffords was shot in the head and I couldn't believe — coming from a country with very tough gun control — that the reaction was like a week of horror and mourning ... and then everyone moved on and nothing changed. And since then: massacre after massacre, and something has to give. And I think that the tipping point was Sandy Hook," Morgan said on CBS's "This Morning" on Thursday.
"What we've done by keeping it in the agenda that we have this week is, we made sure this hasn't gone away, and that's the crucial thing," he said.
Radio host Alex Jones, a backer of the petition, appeared on Morgan's show on Monday in an interview that quickly devolved into an on-air confrontation.
"1776 will commence again if you try to take our firearms,” Jones said to Morgan. “It doesn’t matter how many lemmings you get out on the street begging for them to have their guns taken! We will not relinquish them! Do you understand?”
The White House responded to a petition to deport Morgan on Wednesday, saying in a statement, "Let’s not let arguments over the Constitution’s Second Amendment violate the spirit of its First."
Morgan told CBS that guests with extreme views bring attention to his cause and generate interest in the show.
"I want people to see the likes of Alex Jones, Larry Pratt, who I had on last night, Wayne LaPierre. This debate must be heard loud and clear, so that the arguments against gun control are laid bare for what they are, which, in my view, is a dangerous farce," Morgan said.
When asked what has made him so passionate about the issue of gun violence, Morgan recalled government reaction to the 1996 school shooting in Dunblane, Scotland.
"Britain rose up in horror. It wasn't a political issue at all. That's why I'm amazed that it was here. Left and right came together. The public came together and really draconian gun laws were brought in … since then there have been two much smaller mass shootings, that's it, in the entire 16, 17 years. There hasn't been a single shooting at a school," he said.
