One of the first people to highlight widespread plagiarism by now-ousted Harvard president Claudine Gay has bluntly accused her of “lying” by claiming she “promptly requested corrections” to her published work.

Christopher Rufo, a senior fellow at the conservative Manhattan Institute think tank, joined those condemning Gay’s op-ed Wednesday in the New York Times in which she complained of being the victim of a racist “well-laid trap.”

“Claudine Gay is lying in the New York Times,” Rufo wrote on X Wednesday in a blunt response refusing to accept Gay’s take on her scandal.

“She did not ‘promptly [request] corrections,’” he said, noting how Gay and Harvard had for months thwarted The Post’s initial investigation into her plagiarism in October, which was then dismissed as being “demonstrably false.”

“She denied the allegations, intimidated the New York Post into silence, and then corrected them only under duress,” he wrote.

“There are still dozens of uncorrected instances of plagiarism,” he claimed of the now dozens of allegations over her work.

Gay, 53, claimed in her op-ed that she was a victim, rather than someone her Ivy League school admitted failed to live up to its scholarly standards and one who admits botching her handling of antisemitic threats on campus.

New York Congresswoman Elise Stefanik has also blasted Gay’s op-ed, saying “This was not a ‘well-laid trap’ (to properly cite the disgraced @Harvard former president Claudine Gay).”

“Contrary to their attempts to distract and assign responsibility elsewhere, everyone knows this was not a ‘well-laid trap’ as one disgraced former university president desperately claimed,” Stefanik wrote on X.

“It wasn’t a trap. It was the university president’s cataclysmic failure on the global stage to answer a straightforward moral question.

“Good riddance.”

Harvard declined to comment Thursday on Rufo’s tweet.

However, the Ivy League school noted that the Harvard Crimson had reported that two journals that published Gay’s work have since received requests for corrections.

Harvard declined to comment Thursday on Rufo’s tweet.

Urban Affairs Review Associate Managing Editor Emily Holloway told the school newspaper it “received the corrections,” and editors at the American Political Science Review confirmed Gay reached out to correct a 2001 paper, the Crimson reports.

The editors said the Review “will publish an appropriate corrigendum.”

Demands for Gay’s resignation began in the fall, when she would not condemn more than 30 Harvard student groups that published a letter holding Israel “entirely responsible” for Hamas’ terror attack.

The calls then ramped up after she refused to say that anyone calling for the genocide of Jews at Harvard would be punished when Stefanik asked her whether calls for the genocide of Jews would violate the university’s code of conduct on bullying or harassment.

“It depends on the context,” the academic replied.

In the aftermath, journalists Rufo and Chris Brunet went public with dozens of instances in which Gay seemed to have nearly replicated passages from others’ work in her 1997 thesis — which has since received three corrections for “instances of inadequate citation.”

Just hours before she announced her resignation on Tuesday, the Harvard professor was again hit with six new plagiarism charges — bringing the total number of allegations against her to well over two dozen.
