…for "making political comments" in class.  There's not much detail here.  We know the Louisiana Governor Jeff Landry has open contempt for the First Amendment and academic freedom, but we also don't know what the remarks were and whether or not they were relevant to the class.  (Professor Levy teaches criminal law and constitutional law, both subjects that often make contemporaneous political events relevant.)  Recall that the AAUP definition of academic freedom in teaching states that, "Teachers are entitled to freedom in the classroom in discussing their subject, but they should be careful not to introduce into their teaching controversial matter which has no relation to their subject."  If the Louisiana Governor were not an authoritarian wannabe, one might be willing to give LSU the benefit of the doubt here.  We'll have to see what information actually comes to light.

ADDENDUM:  There's a bit more detail here, but not much: 

[I]n a classroom of about 82 students, Levy was teaching a class about police and public interactions. His attorney Jill Craft says students took issue with his comments in the confines of teaching the First Amendment.

Craft says a student recorded the lecture and Levy’s now been removed for making political comments, though what those comments were is unclear.

Clearly many "political" comments could be relevant and appropriate in a discussion of police interactions with the public, and the First Amendment.  That a student recorded the class is, of course, creepy.
