Drexel University is recognizing the “significant scholarly contributions” of a professor who notoriously wished for “white genocide” for Christmas.

CNN reported Thursday that Prof. George Ciccariello-Maher would be pursuing “other opportunities” while it lauded his work at the school.

“Drexel University has accepted his resignation and recognizes the significant scholarly contributions that Professor Ciccariello-Maher has made to the field of political thought and his service to the Drexel University community as an outstanding classroom teacher,” the university said in a statement. “Drexel University wishes Professor Ciccariello-Maher well in his future pursuits.”

George Ciccariello-Maher, who taught politics and global studies, announced his resignation Thursday on Twitter, writing that “After Dec. 31, 2017, I will no longer work at Drexel University.”

He called his continued employment “unsustainable” due to threats he says he receives from “right-wing, white supremacist media outlets.”

The professor gained notoriety for a Twitter post last December when he announced “All I Want for Christmas is White Genocide.” When he was called-out for that message, Ciccariello-Maher claimed it was all in fun, a “satirical jab at a certain paranoid racist fantasy.”

Just last March, he tweeted was “trying not to vomit” at the sight of a passenger providing a first-class seat to a soldier. This time, Ciccariello-Maher said his post was misunderstood because he was just upset over U.S. airstrikes in Iraq that he said we were killing innocent civilians.

In the wake of the Las Vegas shootings this October, the professor lamented how the “narrative of white victimization” along with “Trumpism” was the root cause of tragedy.
