The fallout of a House congressional hearing last week involving the leaders of Harvard University, the University of Pennsylvania and Massachusetts Institute of Technology has left Wilmer Cutler Pickering Hale and Dorr in the center, which worked with two of the school presidents, Claudine Gay of Harvard and Elizabeth Magill of Penn.

Teams from Wilmer separately prepared Gay and Magill for their congressional testimony in the weeks leading up to the hearing, according to two sources familiar with the situation. The schools each independently retained Wilmer for the event, with a source noting that the firm has “longstanding relationships” with both universities.
