Transcript: “Face the Nation” excerpt of Norah O'Donnell's interview with Vice President Kamala Harris

NORAH O'DONNELL: Israel launches attack on Iran-

VICE PRESIDENT KAMALA HARRIS: Yes.

NORAH O'DONNELL: -that raised fears of escalating conflicts in the Middle East. What is your message to Iran?

VICE PRESIDENT KAMALA HARRIS: Well, first of all, don't answer. It could be a mistake. And we are ready to defend Israel, as we have done before. We will do it again. But the important point is that there should be a decline in the region. And we are working through diplomatic channels and other channels to ensure that there is economic slowdown in the region.

NORAH O'DONNELL: Is there any indication, based on the intelligence that you've seen, that Iran wants to respond?

VICE PRESIDENT KAMALA HARRIS: I can't speak to that, but we have been very clear as the United States that they should not respond and that it would be a mistake.

NORAH O'DONNELL: What are the consequences if they do?

VICE PRESIDENT KAMALA HARRIS: I'll keep you posted.
