Secretary of State Mike Pompeo commented on the House Democrats' impeachment inquiry Sunday on ABC's "This Week."
STEPHANOPOULOS: Well this is not a commonplace situation, as you know. And you have drawn criticism from professionals. I want to -- Bill Burns, who is the former deputy secretary of state, served Republican and Democratic presidents for over 30 years wrote an article in Foreign Affairs Magazine called "The Demolition of U.S. Diplomacy." And here's how he described what you allowed with Ambassador Yovanovitch. Secretary Pompeo allowed specious opposition research about Yovanovitch to circulate around the department and sat his hands as Trump slandered Yovanovitch on the infamous call with Ukrainian President Volodymyr Zelensky and warned ominously that she's going to, quote , go through some things. He then goes on to say the ghost of Roy Cohn is smiling somewhere, comparing it to McCarthyism. Your response?
POMPEO: That's crazy. I think Bill Burns must be auditioning to be Elizabeth Warren's Secretary of State.
STEPHANOPOULOS: But sir, the question is, did you speak...
POMPEO: I mean, people have opinions, George, everyone's entitled to theirs. Bill Burns is clearly looking for a spot in the next administration. That's fine. He's entitled to that view. I have to tell you, I've had a number of foreign service officers walk into my office and tell me how much they appreciate the way we're handling this process.
STEPHANOPOULOS: And finally, sir, one more quote from Mick Mulvaney on Thursday where he was describing how he saw the foreign service professionals going up to testimony on Capitol Hill this week. Let's listen.
MULVANEY: What you're seeing now, I believe, is a group of mostly career bureaucrats who are saying, you know what, I don't like President Trump's politics, so I'm going to participate in this witch hunt that they're undertaking on the hill.
STEPHANOPOULOS: Is that how you view those who are testifying?
POMPEO: No, I have a different view. My view is that each of us has a solemn responsibility to defend the constitution and to speak the truth. I said this the other day, I hope those officers who go to Capitol Hill will speak truthfully, that they'll speak completely. I only wish that this is a process that merited such a response. This has been unfair in the Nth degree. We have got officers up there to testify about important security related matters without a State Department lawyer in the room and then we're not being prepared -- being allowed to know what it says. We're not able to protect the State Department. We're not able to protect the United States of America. And Adam Schiff ought to be embarrassed by the kangaroo court that he's running.
STEPHANOPOULOS: Will you testify if you're called by the committee?
POMPEO: I've said all along, I'll do everything I'm required to do by law.
