Dr. Fiona Hill, a former National Security Council official who held Tim Morrison’s job until this past summer, will testify at the House Intelligence Committee on Thursday as part of the ongoing impeachment inquiry.

She resigned as Trump’s top Russia analyst days before the July 25 phone call considered the crux of the impeachment inquiry, raging since late September. Hill testified behind closed-doors on October 14.

Hill comes across as a competent expert on Eastern Europe, who was opposed to the president’s style of diplomacy and was outraged by the way former Ambassador Marie Yovanovitch was treated. In her deposition, she claimed there was an “antisemitic conspiracy theory” to attack Yovanovitch and others as supporters of left-wing billionaire George Soros. (Soros is Jewish. Some of the attacks on him are antisemitic; most are not, and are substantive.)

Hill is also part of the ongoing rehabilitation of the public image of former National Security Advisor John Bolton. Democrats once described him as a warmonger; now that he may have had a falling out with President Donald Trump, he is a hero. Hill will quote Bolton as saying that Bolton was opposed to what U.S. Ambassador to the E.U. Gordon Sondland and former New York City Mayor Rudy Giuliani were doing in Ukraine.

Like Lt. Col. Alexander Vindman, who worked closely with her, Hill seems outraged at the president’s informal diplomatic channel. Notably, she also admitted in her deposision to working in the past with “Russia dossier” author Christopher Steele, and she has served on a regional board of George Soros’s Open Society Institute.

Key Democrat Talking Points:

1. Hill was the original source of the quote by Bolton calling Sondland’s efforts with the Ukrainians a “drug deal”: “You go and tell [NSC counsel John] Eisenberg that I am not part of whatever drug deal Sondland and Mulvaney are cooking up on this, and you go and tell him what you’ve heard and what I’ve said.” She explained that Bolton was referring to a potential deal for a meeting with the new Ukrainian president in the White House in exchange for investigations into the 2016 elections, and into the Burisma company, which was linked to Joe and Hunter Biden. Bolton also said that Giuliani “is a hand grenade that is going to blow everybody up.”

2. In their “key excerpts” document, Democrats point out that Hill testified that “Ambassador Marie Yovanovitch’s removal was the ‘result of the campaign that Mr. Giuliani had set in motion.’”

3. Democrats will point out Hill’s concern about the damage the president’s request might do to the close relationship with Ukraine, which he will argue is in the national security interest of the United States.
