Ms. Winner may have thought she was mailing the documents to Mr. Greenwald and Ms. Poitras, who went to great lengths to protect Mr. Snowden.

He told me that he considered its claims about Russian hacking during the 2016 race “wildly overblown” and that it didn’t include direct evidence to persuade him otherwise.
