URBANA, Ill. (AP) — The University of Illinois is facing scrutiny as classes resume from some of its faculty, other academics and students over its decision to rescind a job offer to a professor after his prolific, sometimes profane use of Twitter to voice anger at Israel.

Phyllis Wise, the chancellor of the university’s Urbana-Champaign campus, says she decided not to hire Steven Salaita, a professor of American Indian studies, over concerns about what she called demeaning and abusive language. She heard by email from several dozen students, parents and financial donors expressing concerns, some of whom accused Salaita of anti-Semitism.
