Can anyone connect me to a link to Trump saying he asked Ukraine to dig deep and investigate Joe Biden?

A number of you are saying you saw on the news where Trump admitted publicly to pressuring the new Ukraine president to investigate or dig up dirt on Joe Biden.

Nothing like this is in the actual transcript, so I don’t know why Trump would say this. All links I have seen thus far are saying that Trump’s urging the Ukraine to investigate corruption was in “obvious reference” to Joe Biden for Trump’s political campaign.

I’d just like to see some video footage where Trump actually says this.
