The USA Freedom Act expands that so now we have cell phones, now we have Internet phones, now we have the phones that terrorists are likely to use and the focus of law enforcement is on targeting the bad guys.

If I'm elected president, we will secure the border. We will triple the border patrol. We will build a wall that works and I'll get Donald Trump to pay for it.

I think if you're at home and you don't want Donald Trump to be the Republican nominee, then the only candidate who can beat Donald is our campaign. And so I would encourage, even if you like another candidate, stand with us if you don't want Donald to be the nominee.

We need to learn from history. These same leaders - [Barack] Obama, [Hillary] Clinton, and far too many Republicans - want to topple [Bashar] Assad. Assad is a bad man. Gadhafi was a bad man. Mubarak had a terrible human rights record. But they were assisting us - at least [Muammar] Gadhafi and [Hosni] Mubarak - in fighting radical Islamic terrorists.

We are seeing Republicans uniting behind this [presidential] campaign [2016].

On his [Marco Rubio] Gang of Eight bill, he would have liberalized immigration, but he did not - and he steadfastly opposed any new border security requirements for refugees or students.
