WASHINGTON, Oct 11 – Former U.S. Ambassador to Ukraine Marie Yovanovitch was removed as ambassador after insisting that U.S. President Donald Trump's personal attorney Rudy Giuliani's requests to Ukrainian officials for investigations be relayed through official channels, the Associated Press reported.
