According to Taylor's testimony, Morrison said he had a "sinking feeling" after learning of a phone call between Trump and Gordon Sundland, US ambassador to the European Union, during which Trump asked Ukrainian President Vladimir Zelensky to publicly announced investigations by Joe Biden and debunked conspiracy theory for the 2016 election.
Taylor also described a conversation related to him by Morrison between Sondland and a senior Ukrainian official. Taylor testifies that Sundland has told a Ukrainian official that critical military assistance to the East European country will be withheld unless Zelensky "undertakes" an investigation into Biden.
Taylor said he was "anxious" after hearing the conversation and said he had previously told Secretary of State Mike Pompeo that he "would have to resign" if the US changed its policy to support Ukraine . "Based on my conversation with Mr. Morrison, I was going to do it," Taylor added.
Morrison was ready to resign immediately, people familiar with the matter reported Wednesday. He became the second current White House official to testify on an impeachment investigation two days after Lt. Col. Alexander Windman, an expert on Ukraine and Russia at the NSC, testified that he believed Trump's assurances in Ukraine were undermining US national security.
