URBANA, Ill. (AP) — University of Illinois trustees on Thursday voted not to hire a professor whose anti-Israel Twitter messages were deemed anti-Semitic by some, raising the likelihood of a lawsuit or a financial deal with the professor and further campus protests.

An attorney for Steven Salaita, who last year accepted a job to begin teaching this fall in the university’s Native American Studies Program, said after the vote that they plan to file a lawsuit.
