Gallaudet University's chief diversity officer, Angela McCaskill, has sued the university, saying that she suffered discrimination and retaliation for signing a petition to have Maryland residents vote on a state law permitting same-sex marriage, The Washington Post  reported. McCaskill was briefly placed on leave as some on campus said it was inappropriate for a diversity officer to sign a petition widely viewed as way to block gay marriage. McCaskill has argued that she took no stand on same-sex marriage except expressing a belief that state voters should get to decide the issue. Her suit says that, prior to her leave, she was deputy to the president and associate provost for diversity and inclusion, as well as chief diversity officer. Since then, she says, her title has become chief diversity officer. Gallaudet officials declined to comment on the suit.
