It's Trump's chief of staff. And her words were a bit minced.
Ok, I looked it up. They heard the word "alcoholic," and ran with it. From the article I was reading:
The comments, made in conversations over the past year with author Chris Whipple, are striking both in candor and topic. Wiles — who claimed Tuesday that her words were taken out of context in a “hit piece” — is known inside the White House as a careful operator with few internal detractors, unlike the men who held the job in Trump’s first term. She has retained Trump’s confidence in part by running a functional West Wing that doesn’t attempt to constrain the president’s impulses.
Trump regularly refers to his top aide as the “most powerful woman in the world,” with the ability to influence global affairs in a single phone call. While she is a near-constant presence during his meetings and public appearances, her public remarks during Trump’s second term have been limited to a handful of friendly interviews.
Her low profile made her comments to Whipple, whose book “The Gatekeepers” is considered a seminal work on the chief of staff role, all the more striking.
Wiles said Trump governs with “a view that there’s nothing he can’t do. Nothing, zero, nothing.”
“High-functioning alcoholics or alcoholics in general, their personalities are exaggerated when they drink,” she said. “And so I’m a little bit of an expert in big personalities.” The article notes she grew up with an alcoholic father — the legendary sportscaster Pat Summerall.
