LawLawyers for former national security adviser John Bolton have had talks with the impeachment inquiry committees about a possible deposition, according to a source familiar.
Former NSC official Fiona Hill testified before the committee last week that she saw "wrongdoing" in the American foreign policy and tried to report it to officials including the National Security Council's attorney, according to multiple sources.
"She saw wrongdoing related to the Ukraine policy and reported it," one source said. The same source told CNN that Hill testified that Bolton referred to Giuliani -- Trump's personal attorney -- as a "hand grenade" who was "going to blow everybody up.”
Hill additionally told lawmakers about what she described as a rogue operation carried out by US Ambassador to the European Union Gordon Sondland and White House acting chief of staff Mick Mulvaney, which Bolton characterized as being like a "drug deal," that source said.
Another source familiar said Hill testified about a July 10 meeting on Ukraine where Sondland discussed investigations, something that was interpreted as a reference to the President's call for investigations into the Bidens.
Bolton and Hill both were concerned about the comments, and Bolton urged Hill to report the incident to National Security Council lawyer John Eisenberg, according to the source familiar with her testimony.
Top US diplomat to Ukraine Bill Taylor told Congress that Bolton had expressed concerns about a call between President Trump and Ukrainian President Volodymyr Zelensky, according to Taylor's opening statement. “Ambassador Bolton opposed a call between President Zelensky and President Trump out of concern that it would ‘be a disaster,'" Taylor wrote.
