In September 2019, it was reported that Trump had pressured Ukrainian president Volodymyr Zelensky to investigate alleged wrongdoing by Biden and his son Hunter Biden. Despite the allegations, as of September 2019, no evidence has been produced of any wrongdoing by the Bidens. The media widely interpreted this pressure to investigate the Bidens as trying to hurt Biden's chances of winning the presidency, resulting in a political scandal and Trump's impeachment by the House of Representatives.
