A committee at a California university has cleared a professor who sent an e-mail comparing Israel's policies in Gaza to the Holocaust.
Officials at the University of California, Santa Barbara, sent a letter Wednesday to sociology professor William I. Robinson saying the committee had closed the matter.
In January, Robinson offended some students and others with an e-mail to his "Sociology of Globalization" class that juxtaposed grisly photos from the Nazi era with a recent Gaza offensive.
Jewish groups called the e-mail "hate spam" and claimed Robinson violated university policies barring professors from intimidating students and using campus resources for political reasons.
Robinson has said his justified criticism of Israel's policies should not be confused as anti-Semitism.
