Where was Trump's promise? Where was the quid pro quo?
"President Trump in a July phone call repeatedly pressured the president of Ukraine to investigate Joe Biden s son, according to people familiar with the matter, urging Volodymyr Zelensky about eight times to work with Rudy Giuliani on a probe that could hamper Mr. Trumps potential 2020 opponent." -- WSJ 9/21/19

We now know this is a lie. The transcript shows the Biden name once and the focus was on the fired Ukrainian prosecutor. There's enough in the transcript for the DemonRats to keep a pseudo aka fake narrative running with their news outlets for months.
But if they press, then they have to come to terms with Biden actually did what they accuse Trump of doing. Of course there will be no inquiry in that and even now the GOP Senate and DoJ has been silent other than Lady Lindsey calling for a probe.
