The second day of the public hearings in the impeachment investigation into President Donald Trump began on Friday, marked by the testimony of former US Ambassador Marie Yovanovich, who was sacked by the president in May.
US House Democrats launched an impeachment probe into President Trump on 24 September following claims by an alleged intelligence community whistleblower that Trump had threatened to withhold military aid to Ukraine unless Ukrainian President Volodymyr Zelensky investigated former Vice President Joe Biden and his son Hunter during a phone conversation that took place on 25 July.
Trump denies any wrongdoing and insists that the phone call with his foreign counterpart was "perfect".
