Head of the U.S. Diplomatic Mission to Ukraine William Taylor and State Department official George P. Kent testified during public hearings, Voice of America reports.
"In mid-July, I became aware that the precondition for the meeting desired by President Zelensky was the investigation into Burisma and the unconfirmed allegations of Ukraine's interference in the 2016 US election. It was also understandable that these conditions were initiated by an unconventional channel of policy towards Ukraine, which, as I understand it, was regulated by Mr. Giuliani," Taylor said.
He added that "after a call with President Trump, a representative of his staff asked U.S. Ambassador Gordon Sondland what President Trump thinks of Ukraine. Ambassador Sondland responded that President Trump is more concerned about the Biden investigation that Giuliani insisted on.
"I was talking about my concern that Hunter Biden's status as a company leader could create a conflict of interest. Let me be clear: I have not seen any attempt by U.S. officials to conceal Burisma from a thorough investigation," Kent said.
As we reported earlier, House Intelligence Chairman Adam Schiff made it clear that whistleblower won't be testifying in the impeachment inquiry, arguing that the individual's testimony would be "redundant and unnecessary", CNN reported.
House Republicans earlier Saturday had submitted a list of witnesses to Democrats that they'd like to testify as part of the chamber's impeachment inquiry into President Donald Trump and Ukraine. The list included the whistleblower and former Vice President Joe Biden's son Hunter Biden.
However, Schiff does not think that whistleblower's testimony would do great for the impeachment inquiry.
