We are still a nation of laws. You just have to check with Barack Obama every day to see what they are.

Barack Obama has said he doesn't believe in American leadership or America winning - he is wrong. America can win again and we will win again.

Donald [Trump] is a charming person. He can be fun. He can make you laugh. But he can turn on you. And get nasty and personal and vicious.

We are not any safer through the bulk collection of all Americans' records.

Always be sexy. I salute that message.

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.

If you want a candidate who is led the fight against Obamacare, who will lift the burdens on small businesses and bring back jobs, I'm the only candidate in the race with that proven record.
