Cipollone notified Trump of the committee chairman Jerry Nadler’s refusal in writing.
As the adviser to the head of the White House noted, the reason for the refusal was that no witnesses had been appointed in the case, and it was also unclear "whether the legal committee will be able to provide the president with a fair process through additional hearings."
"Accordingly, in the current circumstances, we do not intend to participate in the hearing on Wednesday," the letter said.
