The American people don't trust the Federal Government to enforce our immigration laws, and we will not be able to do anything on immigration until we first prove to the American people that illegal immigration is under control. And we can do that. We know what it takes to do that.

We can't win - if we nominate someone - if we nominate someone that half of the Republican Party hates, we're going to be fighting against each other all the way to November [of 2016]. We will never win that way.

Here's the bigger problem with all this, we're not interrogating anybody right now. Guantanamo's being emptied by this president. We should be putting people into Guantanamo, not emptying it out, and we shouldn't be releasing these killers who are rejoining the battlefield against the United States.

Mitt Romney understands free enterprise, he has worked in it. He has seen companies succeed and he has seen them fail, too. He knows what people think about when they invest their money.
