Trump, Rudy, and the Russian oligarch: The intertwined branches of a poisoned tree - 2019-11-02
When the House eventually drafts the articles of impeachment, those articles will likely be tailored to a narrow set of issues: Trump's attempted extortion of Ukraine's President Zelensky, the subsequent attempted cover-up, and the obstruction relating to the resulting investigation.
While that package will be sufficient to impeach (irrespective of whether it's successful), the House will be leaving a lot on the cutting room floor.
One branch of this poisonous tree that the media hasn't entirely wrapped its head around is the role of Dmytro (a/k/a Dmitry) Firtash, which branch/branches is/are becoming hard to ignore. Precisely how he connects to the instant matter isn't 100 percent clear, but given what's known it's hard to see how he isn't somehow very connected.
