It's worth nothing that Trump repeatedly claims he does not know Parnas, notwithstanding scores of photos exist featuring the two of them together.
"Get rid of her!" Trump says after Parnas tells him about the ambassador. "Get her out tomorrow. I don't care. Get her out tomorrow. Take her out. OK? Do it."
Yovanovitch, of course, impeded efforts by Trump's personal lawyer Rudy Giuliani to block aid to Ukraine unless that government announced an investigation of Joe Biden's son and also to peddle the lie that Ukraine, not Russia, hacked the DNC and Hillary Clinton's campaign manager in 2016.
Yesterday's release further corroborates Parnas's claims that Trump has vehemently denied. Democrats want to feature Parnas amongst other witnesses during the ongoing impeachment trial, something Republican senators may end up blocking.
