In December 2011, Lisa Troyer, who had been President Hogan's Chief-of-Staff, was accused of sending to the members of the university Senates conference committee an e-mail in support of Hogan's proposal with the signature at the end of the e-mail indicating that it was sent by a university Senator. Troyer denied the accusations, claiming that her email account was hacked. In January 2012, a subsequent investigation, conducted at the university's request by an external firm, concluded that the e-mail in question was indeed sent from Troyer's computer and that that computer had not been compromised.
