Marco Rubio in CBS GOP S.C. Debate

On Families & Children: Make investing in kids deductible like business expenses

On Foreign Policy: Three main threats: Asia-Pacific, Middle East, and Russia

TRUMP: What we want to do, when we want to do it, and how hard do we want to hit? We are going to have to hit hard to knock out ISIS. We're going to have to learn who our allies are. We have allies, we have no idea who they are in Syria. Do we want to stay that route, or do we want to go and make something with Russia? But very important, who are we fighting with? Who are we fighting for? What are we doing?

RUBIO: There are three major threats. No. 1 is, what are we doing in the Asia-Pacific region, where North Korea and China pose threats to national security. No. 2 is, what are we doing in the Middle East with the combination of the Sunni-Shia conflict driven by the Shia arc that Iran is now trying to establish in the Middle East, also the growing threat of ISIS. The third is rebuilding NATO, particularly in Central and Eastern Europe, where Vladimir Putin is threatening the territory of multiple countries.

On Foreign Policy: I voted against the president's inadequate Syria strategy

On Government Reform: No to a simple majority to confirm a Supreme Court justice

A: No, I've never [been in favor]. Today, appellate judges can now be appointed by a simple majority, but not Supreme Court justices. I think today you see the wisdom of why we don't that want to change. Because if that were the case and we were not in charge of the Senate, Harry Reid and Barack Obama would ram down our throat a liberal justice.

On Government Reform: I will reverse US decline, both at home and abroad

On Homeland Security: George W. Bush kept us safe and dealt with Hussein

KASICH: We thought there were weapons of mass destruction in Iraq. Colin Powell, who is one of the most distinguished generals in modern times said there were weapons there. The fact is we got ourselves in the middle of a civil war. The borders of that country were drawn after World War I by Westerners that didn't understand what was happening there. The tragedy of it is that we're still embroiled. If there weren't weapons of mass destruction we should never have gone.

On Immigration: Amnesty means no consequences; I was never for that

Sen. Ted CRUZ: When Harry Reid and Chuck Schumer were leading the fight to pass a massive amnesty plan, I led the fight to defeat that plan. There is a difference between Senator Rubio and me on this question.

RUBIO: Amnesty is the forgiveness of a wrongdoing without consequence and I've never supported that. The only way to make progress on immigration is not just to pass a law that enforces the law, but actually prove that it's working. People want to see the wall built. They want to see additional border agents. They want to see e-verify. They want to see an entry-exit tracking system. After that is in place, then we'll see what people are willing to support.

Donald TRUMP: I don't often agree with Marco, and I don't often agree with Ted, but I can in this case. The weakest person on illegal immigration is Jeb Bush.

On Welfare & Poverty: Poverty means free enterprise not reaching people
