Minneapois ? The Star Tribune said it was reviewing a year’s worth of work by one of its editorial page writers after finding two of his pieces contained similarities to the work of a writer at The New Yorker magazine.

Steve Berg, who has worked at the Star Tribune for 30 years, will not be writing for the paper during the review, said editorial page editor Susan Albright. She cited two editorials, one from Nov. 10 and one from March 27, that contained phrases from or similarities to commentaries by The New Yorker’s Hendrik Hertzberg.

“We want you to know that we are taking this matter very seriously,” Albright wrote in a note to readers published Thursday. “We have an obligation to everyone involved to be fair and deliberate in evaluating this; it is too serious a matter to jump to any conclusions without a thorough review.”

Albright did not immediately return a phone call from The Associated Press seeking further comment.

Similarities between a Nov. 10 Star Tribune editorial and Hertzberg’s Nov. 6 commentary were first brought to light in a Nov. 11 posting on the Twin Cities-based conservative blog Power Line, which has long accused the Star Tribune of having a liberal bias.
