Impeachment inquiry: Trump pushed Ukraine meddling 'fiction' - BBC News
Ex-White House aide says US president ignored advisers who said Russia behind 2016 interference.
There's a very rich profile of Hill in the New York Times.

Ms Hill, 54, had an unusual path to academia. The daughter of a coal miner and a midwife, she had a hardscrabble childhood in northeast England - a childhood that bred toughness, her friends say. Once, when she was 11, a boy in her class set one of her pigtails on fire while she was taking a test. She put the fire out with her hands, and finished the test.

She learned to speak Russian and eventually made her way across the Atlantic to Harvard for a fellowship, where she studied under the scholar Richard Pipes, known for his hard-line views about what was then the Soviet Union.

Ms. Hill’s own views are more nuanced, friends and colleagues say; she is not so much a Russia hawk as a cleareyed realist. She was also very clear about the threat Russia posed to Ukraine.

“She comes from this realist tradition where you start with the proposition that this other actor is capable of killing me,” said Graham Allison, a Harvard political scientist who worked with Ms. Hill on an initiative to teach foreign governments about democracy. “I can’t figure out how to kill them without committing suicide, so now I have to find a way to live with them."

And Hill has since referenced the profile, noting that the hair-on-fire incident had the unfortunate consequence of a bowl cut.

"I looked like Richard III," she said, though some on Twitter have debated the accuracy of the comparison.
