Right, in the exchange following Trump’s unilateral freezing of the Senate’s help for Ukraine to resist Russia’s invasion, the transcript has Zelensky asking about obtaining the military help of the Javelins, and then Trump changes the subject to doing “the favor,” and of working with both Giuliani (his personal attorney) and Barr and the Departments of State and Justice (who so far have denied knowledge of involvement with Ukraine on this) in finding crucial dirt on Biden, his main target so far for 2020.
I imagine the next developments will be finding out what conversations the official whistleblower heard, and exploring if or how the Justice and State departments participated in pushing Ukraine to help the Trump administration damage Biden.
