DON LEMON (HOST): OK, so you wanted to get in on something Angela was saying.

COREY LEWANDOWSKI: I just think it's important to remember, right, that the president of the United States has an obligation to still govern the country. And if he wants to engage in partisan politics, I don't think this is the right venue for it. He wants to go on the campaign trail with Hillary Clinton, absolutely he has the right to do that.

But that also means he becomes fair game for any retort that Donald Trump wants to put on him. And I just think that the decorum of the presidency of the United States, the East Room is not the place to engage in those partisan attacks.

ANGELA RYE: Don, let me just respond, really quickly to this. Let me be very clear on this. Donald Trump has been attacking the president long before he began campaigning for this important office. He is the one who was the spokesperson for the birther movement, and was calling for transcripts for -- and saying the president was an affirmative action admittee of Harvard. So let's --

LEWANDOWSKI: Did he ever release his transcripts from Harvard?

RYE: By the way, tell me about those tax returns, while you're at it.

LEWANDOWSKI: Well you raised the issue, i'm just asking. You raised the issue, did he ever release his transcripts or his admission to Harvard University? You raised the issue, so just “yes,” or “no.”

RYE: Corey? Just a moment, I'm going to Beyonce you. Boy, bye. You just so out of line right now, tell your candidate to release his tax returns.

LEWANDOWSKI: Don't raise the issue if you don't want to address it.

RYE: Two words, tax returns. Tax returns.

LEWANDOWSKI: Harvard University transcripts. You raised the issue, did he ever release them?

LEMON: OK, let me ask you something. Let me ask you something -- What is the importance of Barack Obama's Harvard transcript?

LEWANDOWSKI: It's not, she brought the issue up.

LEMON: I'm asking you, how is -- hold on. How is it germane to the election, and the American people?

LEWANDOWSKI: Look, the only reason it's germane is because she brought the issue up, and said Donald Trump raised the issue of his Harvard transcripts. And I just simply said “have those transcripts ever been released?” And the question was “did he get in as a U.S. citizen, or was he brought into Harvard University as a citizen who wasn't from this country?”
