The documents say that Giuliani was acting with Trump’s “knowledge and consent” to pursue a shadow foreign policy, with a letter signed by Giuliani asking for a meeting with Zelensky and with the approval of Trump.

Sen. Roy Blunt (R-Mo.), chairman of the Senate Rules Committee, said admission of any new evidence is likely to be decided by senators and Chief Justice John Roberts, who is presiding over the trial.

“It sounds like a decision the chief justice and the Senate may have to make,” he said, while downplaying the significance of the Parnas documents.

“My initial view of the evidence last night is, there’s nothing much there that hasn’t been already acknowledged, by either the president or Mr. Giuliani,” Blunt said Wednesday.
