Governor Hogan is withdrawing his offer to participate in two prestigious fellowships at Harvard University, decrying the school’s failure to condemn “antisemitic vitriol” on campus as “a moral stain on the university.”

“I cannot condone the dangerous antisemitism that has taken root on your campus,” the former governor of Maryland wrote in a letter to the university’s president, Claudine Gay, on Monday. He joins a growing list of prominent Harvard affiliates who are cutting ties with the school following its failure to quickly denounce the statement signed by more than 30 Harvard student groups blaming Israel for Hamas’s attacks.

“The lessons of history are clear,” Mr. Hogan wrote, referencing the Holocaust. “We must all do our part to take a clear stand in the face of genocidal acts against the Jewish people or any group.” He added that on the subject of the violence at Gaza, there is “no room for justification or equivocation.” 

Mr. Hogan was poised to teach at Harvard’s Kennedy School of Politics and Chan School of Public Health beginning next month. Once named “America’s most popular governor” by Rolling Stone, he was only the second Republican governor to be re-elected in Maryland’s 246-year history. In a New York Times op-ed in May, he encouraged his Republican colleagues to combat “the excesses of progressive elites” through a “common-sense conservative vision.”

Now, Harvard is losing what would have been a prominent spokesman of that vision on its predominantly liberal campus. “This is not a decision I have taken lightly,” Mr. Hogan wrote in his letter, “but it is my hope that it may help further spur you to take meaningful action to address antisemitism and restore the values Harvard should represent to the world.”
