OXFORD (AP) – The PA Attorney General’s Office has weighed in on a dispute over the leadership of a historically black Chester County university, filing suit against the board of trustees over the process that resulted in the ouster of the university president. Attorney General Josh Shapiro said that the lawsuit argues the Lincoln University board violated notice and agenda requirements and refused to allow participation by members named by the Commonwealth during the July 10 meeting that failed to renew the contract of President Brenda Allen.
