Several sources, including The Daily Caller and Power Line, have posted Jeong's frequent Tweets to that effect. To be fair, the offensive Tweets all date from 2013 and 2014, I've seen nothing newer.
NYT has responded as follows, in part:
We hired Sarah Jeong because of the exceptional work she has done covering the internet and technology at a range of respected publications.I don't remember Walt Mossberg writing anything hateful. Of her intemperate Tweets, NYT notes:
She regrets it and The Times does not condone it.Translation (from swamp-speak): Ambition trumps animosity.
She understands that this type of rhetoric is not acceptable at The Times.
Evaluation: Sophomoric snowflake behavior - not a good look at The Gray Lady.
