It's a badge of shame for the NY Times that will never be eradicated, whether they revoke the prize or not.
Frankly, the Pulitzer Prize means nothing. It's an incestuous pat on the back by leftist journalists to other leftist journalists. I can think of a rude term for it, but this is a family forum.
The Sulzbergers went to Columbia and are very influential with the university. They have long been on its board. The Columbia School of Journalism wants above anything else to get NY Times jobs for its staff. Faculty and journalists exchange roles in their professional careers. So they will continue to butter each other up and cover up any embarrassing little problems.
After all these years and after all that has been revealed, there are still leftists who consider it a sacred mission to cover up for Stalin.
