I usually argue that corrections demonstrate the merits of the media. Thanks to competition, others pounce on errors. And it doesn’t happen often, so you can trust most reporting. But sheesh, CNN. Misstating the date on an email? That’s something you should’ve caught in advance
They say they had multiple independent sources. Two unrelated people making an identical mistake about a date is weird. The generous explanation is they rushed to get an exclusive and were sloppy.
