Award-winning Washington Post columnist resigns after critical op-ed on Jeff Bezos is killed

A columnist who has worked at The Washington Post for four decades resigned on Monday after she said the newspaper's management decided not to run her commentary critical of owner Jeff Bezos' new editorial policy.

"It breaks my heart to conclude that I must leave," Ruth Marcus, who has worked at the newspaper since 1984, wrote in a resignation letter.

Her exit is the latest fallout from the billionaire owner's directive that the Post narrow the topics covered by its opinion section to personal liberties and the free market. The newspaper's opinions editor, David Shipley, had already resigned because of the shift.
