A top US diplomat has told an impeachment inquiry that he followed President Donald Trump's orders to put pressure on Ukraine to investigate his Democratic rival, Joe Biden. President Trump on Wednesday said that Ambassador to the European Union Gordon Sondland’s testimony before the House Intelligence Committee should exonerate him of any claims of wrongdoing in the ongoing impeachment inquiry into him.
The instruction came from Mr Trump's personal lawyer, Rudy Giuliani, Ambassador Gordon Sondland said.
The inquiry is assessing if Mr Trump withheld military aid to Ukraine as a precondition. He denies any wrongdoing.
It is illegal in the US to seek foreign help to gain electoral advantage.
Mr Biden is one of the top contenders for the Democratic nomination for the 2020 presidential election.
Mr Sondland, the US ambassador to the EU, told the latest hearing in the US House of Representatives that Mr Giuliani had sought a public statement from Ukraine's leader, Volodymyr Zelensky, announcing an inquiry into "corruption issues".
Mr Giuliani specifically mentioned the company Burisma - which had the son of Democratic presidential candidate Mr Biden, Hunter, as a board member - and issues surrounding the 2016 US presidential election, he said.
If found guilty in a majority vote in the House, the Republican president will face an impeachment trial in the Senate. But two-thirds of members of that Republican-controlled chamber would then need to vote for Mr Trump to be removed from office.
In his opening statement, he said he had worked with Mr Giuliani "at the express direction of the president". While he is the US ambassador to the EU, Mr Sondland said his brief included work on Ukraine alongside other colleagues - despite that country not being an EU member.
"We did not want to work with Mr Giuliani. Simply put, we played the hand we were dealt. We all understood that if we refused to work with Mr Giuliani, we would lose an important opportunity to cement relations between the United States and Ukraine. So we followed the president's orders," he added.
He then confirmed the president had sought an investigation in exchange for a White House visit for Mr Zelensky - a quid pro quo (a favour in return for a favour).
"I know that members of this committee have frequently framed these complicated issues in the form of a simple question: Was there a quid pro quo? As I testified previously, with regard to the requested White House call and White House meeting, the answer is yes."
President Trump on Wednesday said that Ambassador to the European Union Gordon Sondland’s testimony before the House Intelligence Committee should exonerate him of any claims of wrongdoing in the ongoing impeachment inquiry into him.
Speaking to reporters before departing on a scheduled trip to Texas, Trump claimed that Sondland’s testimony means “it’s all over” for the proceedings and that the House inquiry into Trump should come to a halt.
“I just noticed one thing and that would mean it’s all over,” Trump said on the White House lawn before reading from handwritten notes taken during Sondland’s testimony.
