Despite Giuliani backing out of the original deposition, the two sides continued to negotiate an appearance, which led to a virtual appearance Friday that lasted for more than nine hours, sources said.
Costello declined to comment Friday. A spokesperson for the select committee also declined to comment on Giuliani’s deposition.
A central figure in Trump’s failed bid to overturn the 2020 election, Giuliani was subpoenaed by the committee in January and has been engaging with lawmakers, through his lawyer, about the scope of the subpoena and whether he may be able to comply with some requests.
In its subpoena, the committee alleges that Giuliani “actively promoted allegations of election fraud on behalf of the former President and sought to convince state legislators to take steps to overturn the election results.” The subpoena also states that Giuliani was in contact with Trump and members of Congress “regarding strategies for delaying or overturning the results of the 2020 election.”
This story has been updated with additional details Friday.
