From the article:

"The documents also provide the strongest evidence yet that there was a corrupt understanding involving prosecutor general Yuriy Lutsenko (a Ukrainian official in the previous regime). Lutsenko offered to investigate Burisma and the Bidens - and, in exchange, he insisted that US Ambassador to Ukraine Marie Yovanovitch, whom he had clashed with, be fired. He made this quid pro quo clear in his messages to Parnas."

And twitler did just that. Twitler nothing more than a corrupt Ukrainian's $itch.
