Bill Ackman ramped up his campaign against Massachusetts Institute of Technology president Sally Kornbluth, saying he will begin checks on the work of all of the school’s current faculty members for plagiarism.

The move, announced Friday in a post on X, comes after Business Insider expanded its allegations of plagiarism against Ackman’s wife, Neri Oxman, a former MIT professor. The billionaire investor said that faculty members, including Kornbluth and MIT board members, will be subject to checks using MIT’s own plagiarism standards.
