Kate Hartson, a fit 67-year-old who once ran a small press specializing in dogs, had all the trappings of a liberal book editor, including an apartment on the Upper East Side and a place in Hampton Bays. But she also seemed to be that rarest of figures in New York media: a true believer in Donald J. Trump, people who worked with her said. She published “Triggered” by Donald Trump Jr., Mr. Lewandowski’s “Trump: America First: The President Succeeds Against All Odds” and the work of other Trump die-hards like the Fox News host Jeanine Pirro and Newt Gingrich, the former House speaker. – The New York Times
