This is a serious charge so I won't make an editorial comment other than I expected better of Hedges.

The plagiarism at Harper’s was not an isolated incident. Hedges has a history of lifting material from other writers that goes back at least to his first book, War Is A Force That Gives Us Meaning, published in 2002. He has echoed language from Nation author Naomi Klein. He has lifted lines from radical social critic Neil Postman. He has even purloined lines from Ernest Hemingway.
and two experts agree:
I asked two journalism ethicists to look at the instances of plagiarism described throughout this piece. “These examples suggest not inadvertent plagiarism,” said Kelly McBride, who runs the Ethics Department at the journalism school the Poynter Institute, “but carefully thought out plagiarism meant to skirt the most liberal definition of plagiarism.” Robert Drechsel, the director of the Center for Journalism Ethics at the University of Wisconsin-Madison, noted that the use of material from Klein, Postman, and Hemingway “could be characterized as something that has come to be called ‘patchwriting.’ English and writing professors Sandra Jamieson and Rebecca Moore Howard have defined it as ‘restating a phrase, clause, or one or more sentences while staying close to the language or syntax of the source.’ Whether it happens intentionally, carelessly, or as an oversight, it’s a very serious matter.”
