Mr. Alioto sued the journal for libel and received. Mr. Walsh’s sources, nevertheless, informed him one other model of occasions — that the mayor had lied throughout his testimony within the case.

After holing up in a San Francisco lodge for 3 months to research, Mr. Walsh filed a prolonged story on the matter. A hullabaloo adopted.

A.M. Rosenthal, the highest editor of The Occasions, refused to publish the article. In accordance with letters and memos in a collection of his papers on the New York Public Library, he didn’t assume the piece materially superior what Look journal had revealed.

“I’ve determined to not print the piece,” he wrote to Mr. Sulzberger, “just because because it stands I don’t assume it’s a story that carries the Alioto affair additional sufficient journalistically.” He added, “By the way, I’m completely glad as to the accuracy of the statements within the story.”
