Harvard President Claudine Gay recently requested corrections for two of her academic papers, but she did not address even clearer examples of plagiarism from earlier in her academic history at the school, according to a CNN analysis of her writings.

In response to accusations of plagiarism, the embattled Harvard president recently submitted corrections to two papers she wrote as a professional academic in 2001 and 2017. But a CNN examination of Gay’s published works documented that Gay committed other, clearer examples of plagiarism while she was studying for her PhD at Harvard in the 1990s.

Those include an instance in her dissertation where she copied lines verbatim from another source without citation.
