From Wikipedia: Laura Callahan is a former senior director at the United States Department of Homeland Security who resigned after an investigation revealed that she had obtained academic degrees from a diploma mill. Callahan had also served as Deputy Chief Information Officer (CIO) of the US Department of Labor and was previously a senior information technology (IT) manager at the White House. Through her work in the latter position, Callahan had been involved but not responsible for computer problems that caused thousands of email messages to escape the reach of a congressional subpoena.
