White House accused of cover-up

The whistleblower's complaint that sparked an inquiry into US President Donald Trump's phone call with his Ukrainian counterpart took center stage on Thursday during a heated congressional hearing.

An unclassified version of the complaint was publicly released on Thursday shortly before Acting Director of US National Intelligence Joseph Maguire testified before the House Intelligence Committee about his handling of the complaint.

Filed in mid-August with the Office of the Inspector General of the Intelligence Community, the complaint by an unnamed intelligence official centers on Trump and his July 25 phone call with Ukrainian President Volodymyr Zelenskiy that has ignited Democrats' call for House impeachment hearings.
