According to sources in The New York Times, this information was provided to lawmakers in the special intelligence committee of the US House of Representatives Fiona Hill, who was previously the senior director for Russia of the White House National Security Council. On Monday, closed hearings were held with her participation.
According to the newspaper, Bolton compared the activities of Giuliani in Ukraine with the preparation of a drug deal. He instructed Hill to inform legal advisers at the NSS about what was happening. He himself insisted that he had nothing to do with it.
According to sources, Hill told lawmakers that Bolton called Giuliani a grenade that would explode sooner or later and harm others. In July, Bolton allegedly argued about Giuliani with Gordon Sondland, the US Permanent Representative to the EU.
