According to Alexander Vindman, one of the main White House experts in Ukraine and a witness to the conversation between Trump and Zelensky, he tried to make corrections to the publication, but only partially succeeded.
One of the edits that were not included into the final version of the transcript concerns Trump’s words about the existence of some kind of audio recording in which the former US Vice President Joe Biden talks about corruption in Ukraine. The second is Zelensky’s mention of the energy company Burisma Holdings, in which, as it is known, the son of Joe Biden Hunter worked for many years until April, 2019.
