A top US official has said a phone call the US president made to ask Ukraine to investigate political rivals was “improper”.
Lt Col Alexander Vindman was testifying before the US House intelligence committee as part of the impeachment inquiry into Donald Trump.
He said Mr Trump had made inappropriate political demands of his Ukrainian counterpart during a July phone call.
The inquiry is investigating whether presidential power was abused.
Live: Top aides air fears over Trump call The impeachment story explained Who’s who in Trump whistleblower story? What Trump’s Ukraine phone call really means Why Ukraine is so important to the US It seeks to establish whether Mr Trump withheld US military aid to Ukraine in order to pressure the country’s new leader, Volodymyr Zelensky, into announcing a corruption inquiry into Joe Biden, Mr Trump’s Democratic rival for the US presidency.
What did Vindman say? The White House National Security Council (NSC)’s top Ukraine expert testified that he had been concerned by the president’s demands to investigate Mr Biden.
“It was inappropriate, it was improper for the president to request – to demand – an investigation into a political opponent, especially [from] a foreign power where there is at best dubious belief that this would be a completely impartial investigation and that this would have significant implications if it became public knowledge,” he told the committee.
He had reported the “inappropriate” discussion to NSC lawyers “out of a sense of duty”.

He is a decorated Iraq war veteran and was born in Ukraine; his father made the decision 40 years ago to move his family out of the Soviet Union to go and live in the US.
Who else testified on Tuesday? The other witness in the morning session was Jennifer Williams, a foreign service adviser to Vice-President Mike Pence.
She said Mr Trump’s reference to Mr Biden in the 25 July call with Mr Zelensky had been “unusual” because it delved into domestic US politics.
“The reference to Biden sounded political to me,” she said.

Mr Volker told the hearing President Trump “had a deeply rooted negative view on Ukraine rooted in the past” and despite “positive news and recommendations” being conveyed about Ukraine’s new president “he was clearly receiving other information from other sources, including Mayor Giuliani, that was more negative, causing him to retain this negative view”.
Mr Morrsion – who resigned from his position some weeks ago – says he felt no pressure to quit and feared no retaliation.
In his opening statement he said he did not know the identity of a whistleblower whose report helped start the inquiry.
What is the inquiry about? Mr Trump is facing a process that could eventually see him removed from office.
The inquiry is trying to establish whether or not he improperly sought help from Ukraine to boost his chances of re-election in 2020.
