WaPo trends on WaPo after presidential endorsement news

• An endorsement of Vice President Kamala Harris "had been drafted by Post editorial page staffers but had yet to be published," the Post reports.

Zoom in: Three minutes before noon Friday, Opinion Editor David Shipley sent a newsroom-wide email warning that publisher and CEO Will Lewis would soon have a "significant" announcement about presidential endorsements: "I know there will be strong reactions."

• He got that right. Thirteen minutes later, Lewis revealed that The Post would return to its pre-Watergate stance of not endorsing presidential candidates, partly "as a statement in support of our readers' ability to make up their own minds."

The intrigue: A "clarification" to The Post's own news story highlighted the intrigue:

"This article has been revised to clarify that the decision not to publish presidential endorsements was made by the owner of The Washington Post, Amazon founder Jeff Bezos. The decision was announced by the publisher of The Post, William Lewis."

State of play: An Opinion section rebellion grew through the evening as nine, then 11, 12, 13, now 16 columnists signed onto a statement saying their employer's "refusal to endorse a presidential candidate is a mistake."

• Ruth Marcus, a Post columnist who's a Harvard law grad, called it "the wrong choice at the worst possible time."
• Editor at large Robert Kagan resigned in protest.
