An attorney for acting White House chief of staff Mick Mulvaney said Fiona Hill's testimony was "riddled with speculation and guesses" about any role that he played with Ukraine.
Mulvaney's lawyer Robert Driscoll said Hill "bases much of her testimony about him on things allegedly heard from unnamed staffers, guards in the West Wing, and 'many people.'”
Driscoll said that Mulvaney never met Hill and called the impeachment inquiry a "sham."
Why this matters: Hill first testified behind closed doors that it became clear during a July 10 meeting at the White House that an Oval Office visit for Ukraine’s president was contingent on him opening an investigation into President Trump’s political rivals.
Hill told lawmakers that Gordon Sondland, the US ambassador to the European Union, said there was an agreement with Mulvaney that “they would have a White House meeting or, you know, a Presidential meeting, if the Ukrainians started up these investigations again.”
In her public testimony today, Hill said "it struck me...when you put up on the screen Ambassador Sondland's emails, and who was on these emails, and he said these are the people who need to know, that he was absolutely right," Hill said, referencing emails Sondland had sent to officials that included Mulvaney. "Because he was being involved in a domestic political errand. And we were being involved in national security foreign policy. And those two things had just diverged."
