The California State University, Fresno professor who tweeted “Trump must hang” said in a Sunday article he wished he had made his Twitter account private.

Lars Maischak, a history professor at the university, made the comment in an interview with Politico. Fresno State banned Maischak from the university campus after The Daily Caller News Foundation uncovered them in April and relegated the professor to converting two classes to online formats.

“I would probably have made the Twitter account private, had I realized you could easily do that,” said Maischak to Politico.

The professor had tweeted “To save American democracy, Trump must hang. The sooner and higher the better” and “Justice = The execution of two Republicans for each deported immigrant,” among other remarks. After the election, Maischak argued to his students that Trump could be executed, like past fascist leaders, but told Politico that “it got students who voted for Trump very angry.” After being kicked off-campus, however, Maischak reports that his students mostly supported him.
