One of the things that I have encouraged President Trump to do, and I'm optimistic about this, is to take on directly the regulatory state; to take it on, to fire bureaucrats.

The Tsarnaev brothers, the elder brother made a public call to jihad and the [Barack] Obama administration didn't target it.

Congress needs to send a strong signal that direct communication with the leader of the free world is a privilege, particularly for a regime that has been as hostile as Iran has been towards America for more than three decades. President Rouhani needs to take these two simple steps to demonstrate good faith before any further discussions.

I introduced bill saying we need more security, we need more scrutiny. Once again, Marco [Rubio] opposed this. So Marco can't have it both ways. He thinks he wants to be this, "Oh, I'm great and strong on national defense." But he's the weakest of all the candidates on immigration. He is the one for an open border that is leaving us defenseless.

We need a president who stands up, number one, and says, we will defeat ISIS. And number two, says the greatest national security threat facing America is a nuclear Iran.

I do think we should be focused on substance and record. If you want a candidate who opposes amnesty, who opposes citizenship for the 12 million people here illegally, I'm the only candidate in the race who opposes that.

I believe everyone here has a right to speak out on politics as effectively as possible.
