Kurt Volker, U.S. special envoy to Ukraine, has resigned one day after the release of a whistleblower report alleging a coverup by the White House of a call between President Donald Trump and Ukraine's President, three sources familiar with the matter confirmed to CNN.
Volker has become a key player in the unfolding scandal surrounding the whistleblower complaint concerning Trump's July 25 phone call with Ukrainian President Volodymyr Zelensky, in which Trump pressured Ukraine to investigate former Vice President Joe Biden and his son, Hunter, CNN said.
Volker later set up a meeting between Trump's personal attorney Giuliani, who had been interested in getting Ukraine to investigate Joe and Hunter Biden, and a Zelensky adviser in an effort to get the Biden matter out of official talks.
The news of Volker's resignation comes just hours after the House Foreign Affairs Committee announced they would hold a deposition for him next week.
Volker was appointed by Rex Tillerson, the former secretary of state, on July 7, 2017.
