Rudy Giuliani backed out of a scheduled meeting with the committee investigating the Capitol riot after the panel denied his request to record the proceedings.
Giuliani was scheduled to attend a virtual interview on Friday, but his request to do an audio and video recording of the session had been rejected by the panel, according to his lawyer.
Both sides were still talking after the meeting was canceled.
Tim Mulvey, the January 6 committee's representative, said in a statement on Thursday that Giuliani's request to record the interview was never part of the deal.
Mr. Giuliani had agreed to speak with the Select Committee. He informed the investigators that he would not show up unless he was allowed to record the interview.
He said that Giuliani is an important witness to the conspiracy to overthrow the government and continues to be under subpoena.
The committee will consider all enforcement options if he refuses to comply.
The panel subpoenaed Giuliani along with three other Trump lawyers. Bennie Thompson, the chairman of the bipartisan House panel, said at the time that Giuliani had promoted claims of election fraud on Trump's behalf.
Giuliani had tried to arrange a deal with the panel in which he would give information.
According to The Guardian, a source close to Giuliani said the former New York mayor was eager to record the interview to make sure he would not be at risk of perjury.
It is not known if Giuliani will face contempt of Congress charges. The January 6 committee held other Trump allies in contempt for failing to cooperate.
The panel has been in the inner circle of Trump. Donald Trump Jr. was interviewed by the panel recently, as were other members of the Trump family.
