SEN. TED CRUZ, R-TX: It seems to me that all of us should begin as our foundational document with the Constitution. Would she consider it constitutional for Congress to specify that the First Amendment shall apply only to the following books?
SEN. DIANNE FEINSTEIN, D-CA, SENATE INTELLIGENCE COMMITTEE CHAIR: I'm not a sixth-grader.
Senator, I have been on this committee for 20 years. I have studied the Constitution myself. I am reasonably well-educated. And I thank you for the lecture.
So, I come from a different place than you do. I respect your views. I ask you to respect my views.
CRUZ: And, yet, at the same time, I would note that she chose not to answer the question that I asked, which is, in her judgment, would it be consistent with the Constitution for Congress to specify which books are permitted and which are not and to use the specific number...
FEINSTEIN: The answer is obvious. No.

NEIL CAVUTO, HOST: OK, that went well, Dianne Feinstein apparently still stewing over that nasty tit-for-tat with Texas Senator Ted Cruz, calling him arrogant and patronizing in an interview today.
To Senator Cruz himself, ready for some responding today.
Senator, good to have you. What did you make of that, arrogant and patronizing?
CRUZ: Oh, Neil, it's quite great to be with you.
Listen, other senators can choose to hurl whatever insults they like my direction. I have no intention of reciprocating; 26 million people in Texas expect me to come here every day and represent them and in particular to raise the sorts of questions that I raised at that hearing, which is, what are the limits of the Constitution?
And I got to tell you there are a lot of politicians in Washington, both Democrats and Republicans, who have lost sight of the constitutional limitations. I have to tell you, the reaction at the Judiciary Committee hearing when I raised the textual limitations of the Second Amendment and the Bill of Rights, those reactions were reminiscent to Nancy Pelosi's reaction when she was asked where in the Constitution is the authority for ObamaCare?
And her answer was -- quote -- "Are you serious? Are you serious?"
There are a lot of people who don't think it's serious to recognize the limits of the Constitution. I think that's the obligation of every one of us.
CAVUTO: She seemed in her approach to be saying, look here, whippersnapper, I have been around here for, whatever it was, 20 years.
CAVUTO: And you have got to get - learn your place. Now, that is just my interpretation here. But the others have said, as I'm sure it's not news to you, Senator, that as a freshman senator, you are in a unique and special club and you're not following the rules of decorum in that club. What do you say?
CRUZ: Well, I think there are several other senators who have decided to insult me personally.
And my consistent pattern is, I'm not going to do the same. They can throw any insults they want. My focus has been and will remain on the substance. For example, the response that was ultimately given in that exchange was that the Heller Supreme Court decision gave Congress the authority to represent assault weapons.
But what nobody got into is what Heller said. Let me point out, Neil, I know exactly what Heller said because I represented 31 states in the Heller case, was an active part of litigating it. And what the Supreme Court said in Heller is that the Second Amendment allows -- quote -- "dangerous and unusual weapons to be prohibited."
And then the example it gave was machine guns and sawed-off shotguns. But it also said that weapons that are in -- quote -- "common use" cannot be prohibited consistent with the Second Amendment. And one of the many problems with the so-called assault weapons ban is it's trying to ban a semiautomatic rifle, effectively a deer rifle with certain cosmetic features of which there are over four million in circulation.
And under the explicit terms the Supreme Court's decision in Heller, you cannot ban a firearm that is in common use by the American citizen ready to defend homes and their families. My focus is on the substance, not on whatever the emotion or anger might be on the other side.
CAVUTO: I see. But it's not just the other side, right, Senator?
There was a dustup with Senator McCain without calling him by name and the feeling being that you and maybe Senator Rand Paul were sort of representing a new wing of the party that wasn't...
CAVUTO: ... going to be following, for want of a better term, the old wing of the party. And then it got to be what seemed like a tit-for- tat between you guys and Senator McCain, an issue I raised with him just a little earlier. I want your reaction to this.

SEN. JOHN MCCAIN, R- AZ: In an interview, I said that Senator Paul and Senator Cruz were wacko birds. That was inappropriate. And I apologize to them for saying that, because I respect them both.
And I respect what they stand for and what they believe in.
(END VIDEO CLIP)
CAVUTO: How do you feel about Senator McCain?
CRUZ: Well, I appreciate Senator McCain's graciousness in saying that.
On the substance, if it makes us wacko birds to stand for liberty, to stand for the Constitution, then that is badge of honor I wear proudly. But, more substantively, I will point out yesterday was the 40th anniversary of John McCain's being released from a prisoner of war camp in Vietnam.
And I took to the Senate floor yesterday to commemorate and to honor John McCain for his valor, for his integrity, for his incredible courage to turn down early release and instead to spend years more in torture for his country.
And, so, whether -- whatever senators may choose to say disparaging things about me, I have no intention of doing the same. My focus, my job is to stand up for principles of liberty and to stand for the Constitution.
