Given the primacy of this question about what Ukraine did, it’s worth outlining the evidence that Republicans have pointed to during the impeachment hearings and on social media as constituting Ukrainian interference in the 2016 election. Ukraine's interference in the 2016 election against Donald Trump was well documented in multiple mainstream news reports. The exception is the one about “Moscow’s cyber warriors,” which is obviously a report on Russian interference itself that happened to be staged in Ukraine. It’s important to compare the Ukrainian “interference” outlined by Vogel and Stern with what’s known about Russian interference. It’s important to note: Vogel and Stern were writing well before Mueller was appointed or any specific details of the Russian interference effort were documented by federal investigators.
