"They're lying," Fisher says. "I placed myself in that job, not Brown Mackie."
Sobek says the data offer other striking examples that don't hold water with him.
He pointed to how EDMC claims other students were placed in jobs related to their degrees, such as a fashion marketing graduate, an accounting major and a business graduate. He says the EDMC data he provided show the fashion marketing student was actually selling shoes at a Converse outlet store, while the accounting graduate was working at McDonald's as a cashier.
As for the related job the business graduate was counted as receiving after graduation, Sobek says the data reveal he was actually working as a janitor.
EDMC declined an interview with ABC News but says in a statement, "We believe that the claims raised [by Jason Sobek] are wholly without merit.
"We understand that Sobek has made statements to ABC News alleging that EDMC's institutions have made false statements concerning career placement statistics. It is noteworthy that Sobek was not employed at EDMC in a career services role."
The statement went on to say, "For more than 40 years, EDMC schools have adhered to the highest ethical standards."
ABC News asked Senate Majority Whip Dick Durbin of Illinois, a critic of the way many for-profit colleges have operated, to review the documents Sobek provided.
"It's just plain fraud and your whistle-blower has brought it to light," Durbin told ABC News.
"These students get sucked in by these ads, sign up for debt, sign up for courses that lead to nowhere," Durbin says.
Fisher, who says she is reeling in debt and that prospective employers do not take her new degree seriously, says the school had no right to hold up her job at Walmart as a placement success to prospective students.
"I'm about $24,000 in the hole for a degree I can't use," she says.
