(CNN) Rudy Giuliani, former President Donald Trump's onetime personal attorney and a lead architect of his attempt to overturn the 2020 election results, on Friday met with the House select committee investigating the January 6, 2021, insurrection, two sources told CNN.
Giuliani's original deposition with the committee had been postponed after the former New York City mayor asked to record the interview, with both audio and video. At the time, Giuliani's attorney Robert Costello said the committee rejected that request.
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 claims 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."
Several high-profile individuals from Trump's inner orbit have voluntarily spoken with the committee in recent weeks and months. In early May, Donald Trump Jr. met with the committee. And Trump's daughter and former senior White House adviser, Ivanka Trump, was interviewed for nearly eight hours last month; her husband and former White House senior adviser, Jared Kushner, has met with the panel as well.
This story has been updated with additional details Friday.
