to Committee members by October 15, 2019. On October 2, 2019, Steve Linick, the State Department's inspector general, delivered a 40-page packet of apparent disinformation regarding former vice president Joe Biden and former ambassador to the Ukraine, Marie Yovanovitch, to Capitol Hill. Linick told congressional aides his office questioned Ulrich Brechbuhl, Pompeo's advisor about the origins of the packet. Brechbuhl noted the packet came to him from Pompeo, who said it "came over", and Brechbuhl reportedly presumed it was from the White House. Later that day, Giuliani acknowledged he passed the packet to Pompeo regarding the Ukraine and attacks on Yovanovich. In a November 2019 interview he confirmed that he had "needed Yovanovitch out of the way" because she was going to make his investigations difficult. "They (the State Department) told me they would investigate it," Giuliani added. Giuliani persuaded Trump to remove Yovanovich from office in spring 2019. By April 2021, the U.S attorney's office in Manhattan was investigating the role of Giuliani and his associates in Yovanovitch's removal. U.S. ambassador to the European Union Gordon Sondland testified that Trump delegated American foreign policy on Ukraine to Giuliani. The late 2019 impeachment inquiry against Donald Trump centered around Giuliani's actions involving Ukraine. In the compiled testimony and in the December reports of the House Intelligence Committee, Giuliani's name was mentioned more than any but Trump's. Some experts suggested that Giuliani may have violated the Logan Act. On November 22, 2019, Giuliani sent a letter to Senator Lindsey Graham, chairman of the Committee on the Judiciary, informing him of at least three witnesses from Ukraine who Giuliani said had direct oral, documentary, and recorded evidence of Democratic criminal conspiracy with Ukrainians to prevent Trump's election and, after his election, to remove him from office via contrived charges. Giuliani's letter also claims that the witnesses had evidence of the Biden family's involvement in bribery, money laundering, Hobbs Act extortion, and other possible crimes. The letter sought Graham's help obtaining U.S. visas for the witnesses to testify. The next month, Graham invited Giuliani to share his findings with the Judiciary Committee, and soon advised him "to share what he got from Ukraine with the [intelligence community] to make sure it's not Russia propaganda".
