If you're a doctor, or a scientist, or a computer programmer, it shouldn't matter whether you come from Nigeria, or Norway, or any other country on this earth. Today though we have a system that rewards ties of blood, ties of kin, ties of clan. That's one of the most un-American immigration systems I can imagine.

In military terms, if you're not winning, sometimes you are losing. We've seen the Taliban and associated terrorist organizations make gains in recent years. It's time to stop those gains and roll them back. There's a lot of different techniques to do so, but we cannot allow Afghanistan to once again become an ungoverned country from which terrorist organizations can launch attacks against the United States and our citizens.

It's important to remember that whatever the presidential candidates of either party say, they will have to interact with the United States Congress, particularly the Senate, when it comes to crafting policy.

I never go ballistic, I'm always measured and tempered.

A lot of my opposition to President Obama's policies had behind them 5, 6, 7 years of bad policies that made America less safe in my regard.

Donald Trump, like most Americans, like most Republicans, believe in protecting America's core national interests. He believes as do I, as do most Americans, that we aren't yet doing enough to take the fight to the Islamic State.That the intervention in Libya was ill-considered and slapdash at the time. And we're living with the consequences of it now. That we have to get tougher when it comes to our intelligence and law enforcement practices to stop Islamic terrorism.

It shouldn't surprise any American to know that Russia uses its money and its intelligence services to spread disinformation, use subterfuge and deception and manipulation, to try to divide political opinion within the United States, within any Western European country, or among NATO countries. That's one of the techniques that Russia has used for decades, during the Cold War and during the Putin era.
