Pasadena City College has last its second announced commencement speaker. The college is still facing criticism for withdrawing an invitation to Dustin Lance Black, the film writer, amid reports that the college was offended by a sex tape involving Black several years ago. The college blamed an "honest error" for extending an invitation to Black without following proper procedures. And the college announced  that Eric Walsh, the City of Pasadena’s director of public health, would be the speaker. But on Tuesday, the college announced  that Walsh should not speak because of "an unforeseen scheduling conflict." A piece in The Los Angeles Times  says that the college has lost credibility due to the rescinded invitation to Black and that students are being embarrassed by the situation.
