"The Post’s decision to edit and repost the Millian stories is highly unusual in the news industry.
Mainstream publications often add corrections to published stories when credible new information emerges...But it’s rare for a publication to make wholesale changes after publication and to republish the edited story, especially more than four years afterward."
Questions raised by some: Why didn't the Mueller investigation reveal the lack of substantive sources?
