But with many Republicans seemingly unmoved, Trump bashed the testimony as "total nonsense" and said he relished the chance to defend himself.
Trump appointed Sondland to the envoy post after the wealthy OR hotelier donated $1 million to his inaugural committee.
US President Donald Trump has unloaded to one of his favourite media outlets, Fox News, after almost two weeks of nationally televised impeachment hearings that have increased the threat to his presidency.
Mr. Trump asked "so he's going to do the investigation?" and Mr. Sondland replied "he's going to do it. President Zelensky is going to do everything you want him to do".
However, despite these wishes, the White House doubts they will be allowed to participate in the Judiciary Committee process because House rules say they can be blocked unless they drop their objections based on executive privilege to allowing investigators access to administration witnesses and documents. Bolton so far has declined to cooperate in the impeachment inquiry. But he suddenly resurfaced Friday on Twitter. His defence is being coordinated by Pat Cipollone, the White House counsel. The RNC raised another $3 million online on the first day of the hearings last week, McDaniel said.
Trump also defended his use of a private lawyer, Giuliani, to work on Ukraine. Mr. Sondland, he said, told him Mr. Trump did not care about the country and only cares about "big stuff that benefits the President - like the Biden investigation".
Various administration officials expressed alarm at Giuliani's actions.
Giuliani said he continues to have a good relationship with the president and that it can be assumed he talks to Trump "early and often". "He is a great person, an iconic figure in this country", he said of the former NY mayor. "He was the greatest mayor in the history of NY and he was the greatest crime fighter probably in the last 50 years", Trump said of Giuliani, who previously served as the mayor of the largest U.S. city and as a federal prosecutor.
"He's also a friend of mine. He is a great person", Trump added. "Are you sure they gave it to Ukraine?"
House Speaker Nancy Pelosi (D-Calif.) announced a formal impeachment inquiry into the president on September 24, seizing on the whistleblower complaint based on a July 25 phone call between President Trump and the Ukrainian president. Burisma had Joe Biden's son, Hunter, on its board.
Polls show American voters believe Biden would have the best shot at defeating Trump.
The whistle-blower and other US officials have accused Trump of using the power of his office to illegally solicit interference from a foreign country in the 2020 USA election. Trump touted that theory again on Friday.
Testimony from Hill and David Holmes, a State Department adviser in Kyiv, capped an intense week in the historic inquiry and reinforced the central complaint: that Trump used foreign policy for political aims, setting off alarms across the USA national security and foreign policy apparatus.

Trump maintained his push for investigations was related to concerns about corruption in Ukraine generally and that the military aid was withheld because, he claimed, other European allies weren't paying their fair share to support Ukraine. They are seeking monetary damages, saying they were put on the no-fly list despite no evidence showing they threatened airline or passenger safety.
"A lot of it had to do, they say, with Ukraine", he began, before alleging that the country has the DNC server that was hacked in 2016.
