New Republic Suspends an Editor for Attacks on Blog

A senior editor at The New Republic was suspended and his blog was shut down on Friday after revelations that he was involved in anonymously attacking readers who criticized his posts.

Lee Siegel, creator of the Lee Siegel on Culture blog for tnr.com, was suspended indefinitely from the magazine after a reader accused him of using a “sock puppet,” or Internet alias, to attack his critics in the comments section of his blog. An editor’s apology replaced the blog on the Web site, announcing that the blog would no longer be published and noting that The New Republic deeply regretted “misleading” its readers.

Franklin Foer, the New Republic’s editor, said in an interview that he first became aware of the accusations against Mr. Siegel on Thursday afternoon, after a colleague noticed a comment in the Talkback section of Mr. Siegel’s blog that accused him of using the alias “sprezzatura” to defend his articles and assail his critics.
