She pushed the effort while she was the head of the National Association of State Boards of Education, USA Today reports, adding that the effort helped Mylan Specialty, the maker of EpiPens, develop a near monopoly in schools.

The more than 400 percent increase in the price of EpiPens in recent years has drawn anger from members of Congress.

"There is justified outrage from families and schools across the country struggling to afford the high cost of EpiPens,” House Oversight Committee Chairman Jason Chaffetz (R-Utah) and ranking member Elijah Cummings (D-Md.), said in a joint statement last week.

The company is under congressional investigation related to price hikes that it announced last month. The committee will hold a hearing on the issue Wednesday, at which Mylan CEO Heather Bresch will testify.

Bresch is the Manchins' daughter.
