it took way too many clicks to get to an article that was actually about why he was fired:

The report said that in 2018, Dr. Katz didn’t fully cooperate with investigators examining a consensual sexual relationship he had with an undergraduate student beginning in 2006, after her junior year, and continuing until her graduation. The student declined to participate in the investigation at that time.

After the 2018 investigation, which found Dr. Katz had violated school policy prohibiting sexual relationships between teachers and the students under their supervision and its nepotism policy, Princeton suspended him for one year without pay.

In 2021, the school’s student newspaper investigated the relationship, and the former student sent a 63-page complaint to the school. That prompted a second investigation, which found two violations of school policy: Dr. Katz didn’t fully cooperate with and misled investigators, and discouraged the former student from seeking psychiatric help when she threatened self-harm Mr. Eisgruber cited those reasons in his written recommendation for dismissal, which was reviewed by The Wall Street Journal. Dr. Katz, who started teaching at Princeton in 1998, has been on paid administrative leave since July.
