TUSCALOOSA, Ala. (AP) - A Tuscaloosa judge is considering whether Greek-letter groups at the University of Alabama can get involved in an election challenge involving a city school board race. A hearing is set for Thursday morning on a request by two fraternities and a member to intervene in a challenge filed by failed school board candidate Kelly Horwitz. Horwitz's case is focusing attention on the university's influential Greek system by claiming members were wrongly encouraged to support her opponent. The Greek groups say they should be involved in the case because questions are being raised about their members. But a lawyer for Horwitz, James Anderson, says private groups shouldn't be allowed to get involved in an election case. Anderson says Horwitz is challenging the residency of as many as 200 student voters.
