University of California, Davis Chancellor Linda Katehi (kuh-TAY'-hee) says her office hired online image consultants to ensure searches showed the university's achievement and not to erase online content.

In a statement released late Monday, Katehi apologizes for "a series of highly publicized missteps" and says the university should have carefully reviewed the "ridiculous" claims made by public relations firms.

Documents obtained by the Sacramento Bee show that UC Davis spent at least $175,000 on image consultants who promised "to create and execute an online branding campaign designed to clean up the negative attention the University of California, Davis, and Chancellor Katehi."

Katehi says the firms were hired to make sure a complete picture of UC Davis turned up for those doing online searches, especially philanthropists.

She says she will hold a series of public forums and media events to answer questions.
