From the transcript of a September 2nd interview with Pence:
Q: Thank you very much, Mr. Vice President. I wanted to ask you about your meeting yesterday with the Ukrainian President and for an update on Ukrainian security aid money. Specifically, number one, did you discuss Joe Biden at all during that meeting yesterday with the Ukrainian President? And number two, can you assure Ukraine that the hold-up of that money has absolutely nothing to do with efforts, including by Rudy Giuliani, to try to dig up dirt on the Biden family?
VICE PRESIDENT PENCE: Well, on the first question, the answer is no. But we — with President Zelensky yesterday, we discussed — we discussed America’s support for Ukraine and the upcoming decision the President will make on the latest tranche of financial support in great detail.
But as President Trump had me make clear, we have great concerns about issues of corruption. And, fortunately, President Zelensky was elected decisively on an anti-corruption message. And he and I discussed yesterday that as he’s assembled his cabinet, and as his parliament has convened, that even in the early days, he informed me that there have been more than 250 bills filed for — that address the issue of public corruption and really restoring integrity to the public process.
I mean, to invest additional taxpayer in Ukraine, the President wants to be assured that those resources are truly making their way to the kind of investments that will contribute to security and stability in Ukraine. And that’s an expectation the American people have and the President has expressed very clearly.
