Former National Security Advisor John Bolton was so alarmed by Rudy Giuliani's efforts to get Ukrainians to investigate President Donald Trump's political opponents that he called it a "drug deal," former White House official Fiona Hill told Congress on Monday.  Hill, the former leading expert on Europe at the Trump White House, testified that Bolton told her that he did not want part of the efforts of Julian and acting White House chief of staff Mick Mulvey, the man in Hill's testimony room, he told NBC News.
The New York Times first reported details of Hill's testimony Monday night.
"I'm not part of any drug deal that Rudy and Mulvaney are cooking," Bolton tells Hill according to testimony, The Times reported. [1
Hill testifies that Bolton told her to report on the situation of the Chief Justice to the National Security Council, John Eisenberg, according to a person in a closed-door hearing room on Monday.
Hill told lawmakers that he believed the incident posed a clear risk of counterintelligence to the United States, Hill told the NBC News in an interview room.
Requests for comment on the White House, Giuliani and Bolton were not returned immediately Monday night.
Also Monday, correspondence between the White House Deputy Counsel and Hill's attorneys indicates that the White House is trying to limit what Hill can tell Congress in its impeachment study.
Letters received from NBC News illustrate that while the White House is not trying to block Hill from giving evidence, he told Hill's attorneys about four areas that could potentially come under executive privilege.
Hill testified under a subpoena Monday before the House. Previously, she agreed to testify in a written request to Congress.
The House has launched an impeachment investigation into issues involving Trump's communication with Ukrainian President Vladimir Zelensky, which included a request for an investigation by Biden and his son.  There is no evidence of wrongdoing by either Joe or Hunter Biden.
