Last week, CNN fired news editor Marie-Louise Gumuchian after it discovered what it described as a series of plagiarized passages in the stories that she wrote for the cable network. About 50 stories containing 128 instances of plagiarism were cited by CNN.

An investigation of Gumuchian’s work determined that many of the allegedly lifted passages came from Reuters, where Gumuchian had worked for nearly a decade before joining CNN. Following the revelations, Reuters declared that it would review Gumuchian’s archive.

It has done so. “We have reviewed her stories when writing for us, and we stand by them,” a Reuters spokeswoman tells the Erik Wemple Blog via e-mail.

Erik Wemple writes the Erik Wemple blog, where he reports and opines on media organizations of all sorts.
