... Hill has spoken of the difficulty of maintaining a consistent U.S.-Russia policy under President Trump, a result of the clash of her "hawkish" view on Russia and Trump's intermittently warm and welcoming approach, and of the difficulty of ascertaining what Trump and Putin discussed in private meetings. Hill believed that Trump idolized Putin and fell into a trap he set at the Helsinki meeting.

Hill's views on Russia could be characterized by increasing pessimism on co-operation with the United States, as she expressed fear that even Russia's foremost oppositional politician, the now-deceased Alexei Navalny, employed populism and had a history of engaging nationalism.

In response to a question from [the House Intelligence Committee's] chairman, Rep. Adam Schiff, Hill stated: "The Russians' interests are frankly to delegitimize our entire presidency... The goal of the Russians [in 2016] was really to put whoever became the president by trying to tip their hands on one side of the scale under a cloud."

In an October 2021 interview, while recounting her tenure at the White House, Hill drew several parallels between Trump and Putin, noting that both leaders had displayed a penchant for personal power, public performance, and used public nostalgia to gain support. Trump for his part described her as "a deep state stiff with a nice accent".
During an interview by The New York Times on April 11, 2022, Hill was asked about the motivation for the January 6 rally and provoking the assault on the Capitol. She responded that it was "Trump pulling a Putin" in that he was attempting to remain in office similarly to Putin's having extended his term, because of Trump's yearning "to stay in power like the strongmen he admired".
I'm pleased to see that she's assisting with the UK's current defence review.
