Republican presidential contenders met again, this time in Las Vegas, for their fifth debate on Tuesday. GOP hopefuls took the stage Tuesday in two rounds: First, four of the lowest-polling candidates — Mike Huckabee, Rick Santorum, Lindsey Graham and George Pataki — went face-to-face. Immediately after, the nine top candidates — Donald Trump, Ted Cruz, Ben Carson, Rand Paul, Chris Christie, John Kasich, Carly Fiorina, Marco Rubio and Jeb Bush — went under the spotlight.
Here are some of the most quotable moments of the night:
On whether he'll run as an independent: "I am totally committed to the Republican Party."
On building a wall to keep out illegal immigrants: “You just have to speak to the folks in Israel. Walls work.”
On Jeb Bush's campaign: "Nobody cares."
On closing the Internet: “ISIS is using the Internet better than we are using the Internet, and it was our idea … I certainly don’t want to let people who want to kill us use our Internet.”
On surveillance and monitoring: “It’s not a lack of competence that is stopping the Obama administration – it is political correctness.”
On border security: “Border security is national security and we will not be letting in the jihadists. We will keep America safe. ... "We will build a wall that works and I'll get Donald Trump to pay for it."
On Islam: “It’s not a war on faith. It’s a way on a political and theocratic ideology that seeks to murder us.”
On dictators in the Middle East: “No one is ever better off with dictators, but there comes a time when you’re on an airplane, they always say, ‘In case of an emergency, oxygen masks will drop down. Put yours on first and then administer help to your neighbor.' We need oxygen right now.”
On his experience: "One of the things that you'll notice if you look through my life is that I don't do a lot of talking, I do a lot of doing."
“Right now, the United States of America is the patient, and it’s in critical condition.”
On a military presence in the Middle East: "If our military experts say we need boots on the ground, we should put boots on the ground."
On the fight against ISIL: “If we ban certain religions, if we censor the Internet, the terrorists have won.”
On Chris Christie: “I think that if you’re in favor of World War III then you have your candidate.”
“ISIS is created and formed because of the abuse that Assad and his Iranian sponsors have rained down on Sunnis in Syria … We need to focus our attention on Iran, because if you miss Iran, you miss ISIS.”
On surveillance: “Everywhere in America is a target for these terrorists. What we need to do is restore those tools that have been taken away by the president and others. Restore those tools to the NSA and law enforcement community.”
On no-fly zones: “Yes, we would shoot down the planes of Russian pilots if they were stupid enough to think that this president is the same feckless weakling that the president we have in the Oval Office is right now.”
On Putin: “Frankly, it’s time we punch the Russians in the nose. They’ve gotten away with too much in this world.”
On partisan fighting: “We’ll never get there if Republicans and Democrats fight with each other … before all of that, we’re Americans, and I believe we need to unify in many ways to strengthen the country.”
"When I see they have a climate conference over in Paris, they should've been talking about destroying ISIS."
“If you want something talked about, ask a man. If you want something done, ask a woman.”
On surveillance: "Why did we miss the Tsarnaev brothers? Why did we miss the San Bernardino killers? … Our government is woefully behind the technology curve.”
“Citizens, it’s time to take our country back from the political class, from the media, from the liberal elite.”
“Government is not innovating. Technology is running ahead by leaps and bounds. The private sector will help."
“If you’re an American citizen and you decide to join up with ISIS, we’re not going to read you your Miranda rights.”
“And beyond that, we must win the information war against ISIS … We have to show what life is really like within ISIS territory.”
On Donald Trump: "He’s a chaos candidate and he’d be a chaos president."
"Donald, you are not going to be able to insult your way to the presidency."
On who is to blame for ISIL (Graham says it's Obama): “I am tired of beating on Bush. I miss George W. Bush.”
On Donald Trump's proposed policy about Muslims: “ISIL would be dancing in the streets, they just don’t believe in dancing.”
On the fight against ISIL: “If you’re not determined to fight it as a war, you’re going to lose it.”
On Muslims serving in the U.S. military: “You are not the enemy. Your religion is not the enemy.”
On a mandatory draft: "If you don't want to be there, I don't want you there."
On GOP candidate Ted Cruz: ”His favorite movie is apparently Princess Bride. Ted, getting in bed with Iran and Russia to save Assad is inconceivable… Princess Buttercup would not like this.”
On women in the military: "I don't care if you're a man or a woman. I care if you're good and capable of doing the job."
On surveillance of Muslims in the U.S.: “You can’t shout fire in a crowded theater … It is not constitutionally protected speech. It should be shut down.”
"I'm a great believer in the first amendment and freedom of speech. I wish we had more of it on our college campuses.”
On Putin: “Do I think we should hug Putin, have a wonderful relationship with the Russians and ride away in the sunset like in the end of Casablanca? No I don’t.”
On young people: "We aren’t going to give you anything. We’re going to give you the opportunity to get off your butt and serve your country and secure your freedom.”
"If (Donald Trump) becomes president, he will do a whole lot more to protect us than Hillary will."
On surveillance of Muslims in the U.S.: "If Islam is as wonderful and as peaceful as its adherents say ... Shouldn't they be begging us to come in and listen?"
“I want my grandkids to grow up not in fear, but in faith and freedom.”
On what's protected by the first amendment: "Islam is not just a religion. It's a political government structure."
“This is an important time in our country’s history. We have entered World War III.”
