The subpoena requires Giuliani, Trump’s personal lawyer and a former mayor of New York City, to produce documents that concern Trump pressuring the president of Ukraine to investigate one of his political rivals, former Vice President Joe Biden.
The subpoena letter is signed by Democratic Reps. Adam Schiff (Calif.), chair of the House Intelligence Committee; Eliot Engel (N.Y.), chair of the House Foreign Affairs Committee; and Elijah Cummings (Md.), who chairs the House Oversight and Reform Committee.
In the letter, the three lawmakers note that Giuliani admitted on CNN that he asked the Ukrainian government to dig up dirt on Biden, whom Trump could very well face off against in the 2020 presidential election.
“In addition to this stark admission, you stated more recently that you are in possession of evidence ― in the form of text messages, phone records, and other communications ― indicating that you were not acting alone and that other Trump Administration officials may have been involved in this scheme,” the lawmakers wrote.
Giuliani must comply with the subpoena by Oct. 15.
Among the required documents are any Giuliani has that are related or refer to Biden’s son Hunter, or to Burisma, the Ukrainian energy company where Hunter once served on the board. Trump has repeatedly pushed the conspiracy theory that Biden once used his power as vice president to help the company by pushing for the firing of the Ukrainian prosecutor investigating Burisma.
The subpoena also calls for any documents or communications that concern U.S. foreign assistance to Ukraine. According to a summary of Trump’s July phone call with Ukrainian President Volodymyr Zelensky, Trump implied that such aid was at stake if the country did not investigate Biden.
Shortly after Schiff, Engel and Cummings announced their subpoena of Giuliani, Trump tweeted a video clip where he defended the call with Zelensky, saying it “was perfect” and claiming that the whistleblower ― an intelligence official who filed a formal complaint about Trump’s Ukraine efforts, and whose identity has not been made public ― is at fault for making a false report.
