NBC News said on Tuesday that it had found instances of plagiarism in 11 articles written by a reporter over the past year.
“In all cases, the passages were not central to the stories, but instead contained supplemental or background material that did not represent original reporting,” the note said.
The network did not name the reporter in its note, but did include links to the articles in question. The author of the 11 articles was Teaganne Finn, who joined NBC News last year as a political reporter and previously worked at Bloomberg as a breaking news reporter. Ms. Finn no longer works at NBC News. She did not immediately respond to a request for comment.
The articles included a report on the partisan political fight over inflation in which two passages were removed and coverage of comments by former President Donald J. Trump on the coronavirus vaccine, which contained several unattributed passages, according to the editor’s note.
Questions about Ms. Finn’s work first arose when one of her articles was being edited, which led to a review of previous articles she had written, according to a person with knowledge of the situation, who spoke on condition of anonymity to discuss an internal matter.
