The board of the San Jose/Evergreen Community College District is promising tighter oversight of senior administrators after the release of a law firm's investigation of certain activities of Chancellor Rosa Perez, who is currently on sick leave and will be leaving her position in June, The San Jose Mercury News reported. The board is also asking the local district attorney to investigate whether Perez violated laws. The law firm's report concluded that Perez may have violated conflict of interest laws by buying a house and sharing expenses with her partner, whom she supervised as an administrator at the college. Further, the report cited numerous trips -- some of which her partner made as well -- as being "not cost effective" for the college district. The investigations were prompted by reports in the Mercury News and KGO-TV. Perez could not be reached for comment.
