Fox Business 2016 GOP primary debate: on Gun Control

Chris Christie: Vetoed a statewide I.D. system for gun owners

CHRISTIE: If you look at my record as governor of New Jersey, I have vetoed a 50-caliber rifle ban. I have vetoed a reduction this clip size. I vetoed a statewide I.D. system for gun owners and I pardoned, six out-of-state folks who came through our state and were arrested for owning a gun legally in another state so they never have to face charges. Two years ago, Marco called me a conservative reformer that New Jersey needed. That was before he was running against me. Now that he is, he's changed his tune. I'm never going to change my tune. I like Marco Rubio. He would be a heck of a lot better president than Hillary Rodham Clinton would ever be.

Donald Trump: Mass shootings are due to a huge mental health problem

BUSH: We don't need to add new rules. We need to focus on what the bigger issue is: we should focus on is the violence in our communities. The other issue is mental health. Why not begin to deal with the process of mental health issues so that people that are spiraling out of control because of mental health challenges don't have access to guns.

TRUMP: What Jeb said is absolutely correct. We have a huge mental health problem in this country. We're closing hospitals, we're closing wards, we're closing so many because the states want to save money. We have to get back into looking at what's causing it. The guns don't pull the trigger. It's the people that pull the trigger and we have to find out what is going on. You get the Congress. You get the Senate. You get together. You do legislation.

Donald Trump: No limits on guns; they save lives

TRUMP: No. I am a 2nd amendment person. If we had guns in California on the other side where the bullets went in the different direction, you wouldn't have 14 or 15 people dead right now. If even in Paris, if they had guns on the other side, going in the opposite direction, you wouldn't have 130 people plus dead. So the answer is no and what Jeb said is absolutely correct.

Jeb Bush: Issue isn't law-abiding owners, but violence & mental health

BUSH: We don't need to add new rules, we need to make sure the FBI does its job. Because that person [the S.C. shooter] should not have passed a background check. The first impulse of Barack Obama and Hillary Clinton is to take rights away from law-abiding citizens. That's what they do, whether it's the San Bernardino attack or if it's these tragedies that take place, I think we need to focus on what the bigger issue is. It isn't law-abiding gun owners. And that's what we should focus on is the violence in our communities. Target the efforts for people that are committing crimes with guns, and if you do that, and get it right, you're going to be much better off than creating a political argument where there's a big divide. The other issue is mental health. That's a serious issue that we could work on. Republicans and Democrats alike believe this.

Mike Huckabee: Completely insane to make buying a gun even harder

HUCKABEE: (LAUGHING) Yes, I did.

Q: You even told gun store owners to ignore the President's orders. Yet, innocent people are dying from gun violence in cities every day. How to prevent guns from falling into the hands of criminals?

HUCKABEE: Well, why don't we start by making sure the Justice Department never does an idiotic program like Fast and Furious where the US Government put guns in the hands of Mexican drug lords? You know, they want to talk about law abiding citizens, I just find it amazing the President keeps saying the gun show loophole. There is no gun show loophole. I promise you I've been to more gun shows than Pres. Obama. I've bought more weapons [there], and you fill out forms. The President also says that it's easier to get a gun now than it is to grow trees. I purchase guns, and I can assure you that it is much more difficult to purchase a firearm than to grow trees.
