Former US Envoy to Ukraine Set to Testify in Impeachment Inquiry VOA News Staff from three U.S. House of Representatives committees at the center of an impeachment inquiry involving President Donald Trump and Ukraine are scheduled to hold a closed-door deposition Thursday with Kurt Volker, the recently resigned U.S. envoy to Ukraine. Questions are likely to focus on a July phone call between Trump and Ukrainian President Volodymyr Zelenskiy, Volker's actions following the call, and the activities of Trump's personal attorney Rudy Giuliani in connection with allegations Trump pressured Zelenskiy to investigate former U.S. Vice President Joe Biden. Those allegations came in a whistleblower complaint made public last week, which said that according to multiple White House officials, Trump also pressured Zelenskiy to "meet or speak with two people the President named explicitly as his personal envoys on these matters," naming Giuliani and Attorney General William Barr. Volker resigned the day after the complaint was released. .
