U.S. lawmakers on Thursday (October 31) heard closed-door testimony from Tim Morrison, the former top Russia specialist on President Donald Trump's National Security Council.
Morrison resigned from his position on Wednesday.
Morrison listened in on a July 25 phone call between Trump and Ukrainian President Volodymyr Zelenskiy at the heart of an impeachment inquiry.
Morrison said the call "could have been better," according to acting U.S. Ambassador to Ukraine
In testimony last week, Taylor also said that Morrison had confided to him on Sept.
7 that he had a "sinking feeling" after a phone conversation in which Trump told another ambassador he wanted Zelenskiy to "go to a microphone and say he is opening investigations of Biden and 2016 election interference." Morrison was mentioned 15 times in Taylor's detailed statement to lawmakers, which described a dipomatic back channel through which Trump had made the release of $391 million in U.S. aid to Ukraine contingent upon Kiev publicly declaring it would investigate the Bidens.
