However, on April 28, 2019, Barr said he might not testify to the Committee because he was displeased about the format of the testimony he is expected to give. Nadler said "The witness [Barr] is not going to tell the committee how to conduct its hearing, period". On the prospect of Barr not showing up, Nadler stated: "Then we will have to subpoena him, and we will have to use whatever means we can to enforce the subpoena". Barr did testify before the Republican-controlled Senate Judiciary Committee on the same topics on May 1. On May 2, when Barr was to testify before the committee, Barr did not show up. Democrats on the House Judiciary Committee, specifically Democratic Representative of Tennessee Steve Cohen, mocked Barr for not showing up, calling him "Chicken Barr". Cohen also brought a bucket of Kentucky Fried Chicken and a chicken prop. On May 3, 2019, Nadler informed Barr that a subpoena had been issued giving him until May 6, 2019, to release the un-redacted Mueller Report. Barr did not comply with the subpoena. The House Judiciary Committee is expected to vote on whether to bring forth Contempt of Congress on May 8. A law issued in 1857 gives Congress the power to issue criminal charges for this matter. On May 8, Assistant Attorney General Stephen Boyd wrote Nadler that Barr would ask Trump to invoke executive privilege to withhold the full report if the Judiciary Committee proceeded to vote on a contempt charge. Boyd wrote in the letter to Nadler saying "We are disappointed that you have rejected the Department of Justice's request to delay the vote of the Committee on the Judiciary on a contempt finding against the Attorney General this morning ... Accordingly, this is to advise you that the President has asserted executive privilege over the entirety of the subpoenaed materials." Also on May 8, Barr wrote a letter to Trump to "request that you make protective assertion of executive privilege with respect to Department of Justice documents recently subpoenaed by the Committee on the Judiciary of the House of Representatives." On May 8, Trump invoked executive privilege for those documents at Barr's request. Trump's announcement of executive privilege came just hours before the House Judiciary Committee planned to vote on whether to hold Barr in contempt. The Committee voted unanimously to reject this assertion of executive privilege and approved a motion put forward by Rep. Matt Gaetz (R-Fl) which states that a vote to hold Barr in contempt would not "be construed as a directive for the Attorney General to violate Federal law or rules." In a 24–16 vote, the House Judiciary Committee approved a motion of Contempt of Congress against Barr.
