The big news here is that none of this was released until after the election. They may be releasing it now to hasten Joe Biden’s departure from the presidency. From John Solomon at justthenews.com:
Vice President Joe Biden’s office was warned in 2015 that the Obama State Department believed the Ukrainian gas oligarch whose firm hired Hunter Biden was corrupt and that some of the evidence supporting that conclusion had been gathered by the U.S. Justice Department, newly released diplomatic memos show.
Then-U.S. Ambassador Geoffrey Pyatt in Kiev alerted Biden’s top advisers to the concerns about Burisma Holdings founder Mykola Zlochevsky shortly before the vice president visited with Ukrainian officials in December 2015.
“I assume all have the DoJ background on Zlochevsky,” Pyatt wrote in an email to top Biden advisers in the White House. “The short unclas version (in non lawyer language) is that US and UK were cooperating on a case to seize his corrupt assets overseas (which had passed through the US).”
