The US Democratic Party has begun a formal impeachment inquiry into President Donald Trump over allegations that he pressured a foreign power to damage a political rival. Top Democrat Nancy Pelosi said the president “must be held accountable”.
Mr Trump has denied wrongdoing and called the efforts a “witch hunt”. There is strong support from House Democrats for impeachment, but the proceedings would be unlikely to pass the Republican-controlled Senate.
The high-stakes move by House Speaker Ms Pelosi, prompted by allegations that Mr Trump pressured the Ukrainian president to investigate his leading political rival Joe Biden, lays the groundwork for a potentially hugely consequential confrontation between Democrats and the president ahead of the 2020 election.
