In a late-night tweetstorm, Randa Jarrar taunted the chorus of people demanding that she be fired from her tenured position at California State University at Fresno after she called the recently deceased Barbara Bush “an amazing racist” and exulted, “I’m happy the witch is dead.”  School officials said they were reviewing the tenured professor’s position, and Castro rebuked Jarrar, saying her remarks left him “shocked, upset, appalled just like everybody else.”  On Tuesday, Castro announced what the university would do about Jarrar’s words: Nothing.
