I will not let anyone into America that I think poses a risk to us.
I think that we have to be constantly asking ourselves, 'How do we calculate the risk?' And sometimes we don't calculate it correctly; we either overstate it or understate it.
In many parts of the world, women and girls are especially vulnerable to HIV/AIDS because they lack control over most aspects of their life. Cultural expectations and gender roles expose women and girls to violence, sexual exploitation and far greater risk for infection.
We now have power under the Dodd-Frank legislation to break up banks. And I've said I will use that power if they pose a systemic risk.
