NBC News said on Tuesday it found instances of plagiarism in 11 articles written by a reporter over the past year.

In a note on its website, the network said an editor’s note was placed on each article and plagiarized sections were removed.

“In all cases, the passages were not central to the stories, but rather contained additional or background material that did not represent the original reporting,” the memo reads.

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. A Bloomberg News spokeswoman declined to comment.

The articles included a report on the partisan political fight against inflation in which two passages were deleted and coverage of former President Donald J. Trump’s comments on the coronavirus vaccine, which contained several unattributed passages, according to editor’s note.

Questions about Ms Finn’s work first arose while writing one of her articles, leading 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. .
