Public hearings in US House of Representatives’ impeachment inquiry of President Donald Trump got under way last week, marking a new phase in the probe. 

The impeachment inquiry is centred on a July 25 phone call between Trump and Ukrainian President Volodymyr Zelenskyy in which the US president asked the Ukrainian leader to investigate former Vice President Joe Biden, who is also a frontrunner in the 2020 Democratic presidential race and his son, Hunter, who had served on the border of a Ukrainian gas company. The request came as Trump withheld nearly $400m in military aid to Ukraine, prompting speculation that the US president was using the money as leverage for the investigation. 

More:

There has been no evidence of wrongdoing by the Bidens. Trump maintains there was no quid pro quo (Latin for “favour for a favour”) and has labelled the impeachment inquiry a “witch-hunt”. 

During the public hearings, lawyers for the committees involved in the investigation will conduct questioning for extended periods of time.
