In the debate hosted by CBS and the Wall Street Journal the GOP hopefuls opened the night honoring the late Supreme Court Justice Antonin Scalia.
Here are the best lines of the fiery debate:
ON NOMINATING JUSTICE SCALIA'S REPLACEMENT
DONALD TRUMP: "If I were president now I would certainly want to try and nominate a justice."
"I think he is going to do it, whether I'm OK with it or not. I think it's up to [Senate Majority Leader] Mitch McConnell and everybody else to stop it," Trump continued. "It's called delay, delay, delay."
JOHN KASICH: "I would like the president to just for once here put the country first."
ON CARSON’S EXPERIENCE
BEN CARSON: “Thank you for including me in the debate. Two questions already. This is great.”
MARCO RUBIO: “We need to put people on the bench that understand the Constitution is not a living and breathing document. It is to be interpreted as originally meant.”
Rubio added, “I do not believe the president should appoint someone.”
ON VLADIMIR PUTIN
DONALD TRUMP: “Call me a genius. I like him so far.”
“Jeb is so wrong. Just so you understand, you know what that is? That's Jeb's special interests and lobbyists talking,” Trump fired at former Florida Gov. Jeb Bush. “Look, let me just tell you something. Jeb is so wrong, wrong. You've got to fight ISIS first. You fight ISIS first.”
Trump continued, “Lindsey Graham, who backs him. Lindsey graham, who had zero in his polls.”
Last month, South Carolina senator and former presidential hopeful, Lindsey Graham endorsed Jeb Bush.
Bush hit Trump back saying: “This comes from a guy who gets his foreign policies from the shows. This is a guy who thinks that Hillary Clinton was a great negotiator in Iran. We're living in dangerous times. This is a man who insults his way to the nomination.”
ON GEORGE W. BUSH
JEB BUSH: “I'm sick and tired of Barack Obama blaming my brother for all of the problems that he's had.”
He continued, “I'm sick and tired of him going after my family. My dad is the greatest man alive in my mind. While Donald Trump was building a reality TV show, my brother was building a security apparatus to keep us safe. And I'm proud of what he did.”
To which Trump responded, “The World Trade Center came down during your brother's reign. Remember that.” He continued, “that's not keeping us safe.”
“This is just nuts,” Kasich interjected.
“I just want to say, at least on behalf of me and my family, I thank god all the time it was George W. Bush in the White House on 9/11, and not Al Gore,” Rubio added.
Trump hit back, “How did he keep us safe when the World Trade Center came down during the reign of George Bush. He kept us safe? That is not safe. That is not safe, Marco. That is not safe.”
"The World Trade Center came down because Bill Clinton didn’t kill Osama bin Laden when he had the chance to kill him," Rubio argued.
ON THEIR TAX PLAN
MARCO RUBIO: “I'm going to have a tax plan that is pro-family because the family is the most important institution in society. You cannot have a strong country without a strong family.”
DONALD TRUMP: “I want everybody taken care of, but we have to take care of our people in this country.”
TED CRUZ: “Marco right now supports citizenship for 12 million people here illegally. I oppose citizenship.”
“Marco went on Univision in Spanish and said he would not rescind president Obama's illegal exclusive amnesty,” Cruz added.
“First of all, I don't know how he knows what I said on Univision because he doesn't speak Spanish,” Rubio quipped.
Cruz responded in Spanish, saying, "Vato, si quieres dicelo ahora mismo, dicelo ahora en Español si quieres.”
Translation: “Dude/Man if you want to tell them now, tell them now in Spanish, if you want.”
JEB BUSH: “The great majority of people that come to this country come because they have no other choice. They want to come to provide for their families.”
Trump argued immigration didn’t become a topic of discussion until he announced his candidacy and went on to say, “The weakest person on this stage by far on illegal immigration is Jeb Bush.”
“But if you want to talk about weakness, you want to talk about weakness, it's weak to disparage women. It's weak to disparage Hispanics,” Bush argued.
ON TED CRUZ
DONALD TRUMP: “You are the single biggest liar. You probably are worse than Jeb Bush."
ON RONALD REAGAN
JEB BUSH: “He didn't tear down people like Donald Trump does. He tore down the Berlin Wall. Great guy.”
ON BEING THE DEMOCRATS' 'FAVORITE' REPUBLICAN
JOHN KASICH: “I love these blue-collar Democrats because they're going to vote for us come next fall, promise you that.”
ON DONALD TRUMP BEING WRONG
“My wife tells me I'm wrong all the time,” Trump joked.
DONALD TRUMP: "If I say a word that's a little bit off color, a little bit, it ends up being a headline. I will not do it again."
