The fast-moving scandal involving President Donald Trump and allegations that he pressured Ukrainian President Volodymyr Zelensky to investigate his political rival Joe Biden and his son, Hunter, has upended politics in Washington, DC, and evolved into a full-blown impeachment investigation. There is no evidence that either Biden did anything wrong.
There are two Ukrainians at the heart of US President Donald Trump's personal lawyer Rudy Giuliani's allegations against former US Vice President Joe Biden and his son Hunter. Both headed Ukraine's prosecutor's office -- Viktor Shokin between 2015 and 2016, and Yuriy Lutsenko between 2016 and 2019.
Former Ukrainian President Petro Poroshenko has told CNN that he had no knowledge about his prosecutor-general's offer to help US President Donald Trump investigate the son of former Vice President Joe Biden, a leading candidate to face him in the 2020 presidential election.
For Rudy Giuliani, the final week of September could very well go down as the most consequential stretch of days in his long public career since he led New York City through the tragedy of 9/11.
