WASHINGTON (Reuters) - A longtime U.S. diplomat who served as President Donald Trump's special envoy for Ukraine will tell his story to congressional committee staff on Thursday as part of a Democratic-led impeachment probe of the Republican president.
Kurt Volker resigned as special representative for Ukraine negotiations on Friday, the day after the public release of a whistleblower complaint that described him as trying to "contain the damage" from efforts by Trump's lawyer Rudy Giuliani to press Ukraine to investigate Democrats.
