The Republicans took up his earlier closed testimony, saying he saw no evidence of compensation for the US Security Assistance and a one-on-one interview.
But Volker, the first witness in Parliament's impeachment investigation, said that since his first statement, "a lot of additional information and perspectives have come to light."
"I have learned many things that I did not know at the time of the events in question," he said. "I knew no connection between the cessation of security assistance and the prosecution of investigations by the Ukraine, which no one had ever told me before, and I never told the Ukrainians such a connection."
Volker said the Ukrainians said they did not want to continue with the statement. Volker said that he thought the matter had been dropped ̵
"These were the last conversations I had about this statement that took place on or about August 17-18 … At that time, I was thinking the idea of making that statement was definite been discarded, "Volker said. "In September, I was surprised to learn that further discussions were going on with the Ukrainians that President Zelensky may have made a similar statement in an interview with the US media as in August."
