Edited sentence: A year after Shireman launched the gainful employment regulatory efforts at the Department of Education, Eisman raised his own concerns about predatory for-profit colleges, first in a meeting with department officials that Shireman attended by phone, and then in a presentation at an investor conference.An investigation by the department’s Inspector General, conducted at the request of two Republican senators, found “no improper disclosure of sensitive information by Department officials in their communications with outside parties.Anonymous letters alleged, without evidence, “stock price manipulation by Shireman and Eisman,” while the industry, using groups it secretly funded, claimed the agency’s rulemaking process was tainted.In response, Shireman has repeatedly denied any conflicts of interest, labeling the attacks as attempts to divert attention from a long history of abuses by for-profit colleges.Since 2010 Shireman has been the subject of an unfounded claim alleging stock manipulation through ties to Steve Eisman, the Wall Street short seller featured in the book and movie “The Big Short.The for-profit college trade association used Eisman’s involvement to portray its detractors as part of a conspiracy with short sellers.” Further inquiries yielded nothing, yet the baseless allegation has occasionally reappeared
