MOVING TO FRONT FROM YESTERDAY--UPDATED
I don't know a lot about this case beyond what is described here, but it sure looks like a First Amendment violation. The important thing to note is that the recent Congressional jihad against speech critical of Israel is having real effects. As the University itself states:
Additionally, the U.S. Department of Education’s Office for Civil Rights (OCR) has recently warned universities that they have the duty under Title VI to take prompt action if it knows, or even should have known, that discriminatory harassment has occurred. The OCR stated that, “…a school violates Title VI when it fails to take adequate steps to address discriminatory harassment, such as antisemitic harassment.”
I expect we will see more cases like this. If anyone has more information, please add links in the comments. I will be moderating comments for relevance, so this is not a general invitation to air grievances: I'd like more information about this case. Thanks.
UPDATE: The AFA letter to Texas Tech, which seems to me exactly right.
