Scott Blackmun, the former chief executive of the United States Olympic Committee who resigned under pressure last February and was heavily criticized for failing to protect gymnasts from being sexually abused by their national team doctor, received $2.4 million in severance pay.

Mr. Blackmun knew about accusations against the doctor, Lawrence G. Nassar, for more than a year before they became public in September 2016 but did not investigate, report or try to stop Dr. Nassar’s behavior, in effect helping to cover it up, according to a scathing report made public last December that was commissioned by the Olympic committee.

The severance payment was revealed in a financial report made public on Wednesday, the eve of the July 4 holiday. The committee, renamed last month as the United States Olympic and Paralympic Committee, or U.S.O.P.C., defended the severance pay in a statement from Susanne Lyons, the chairman of the board of directors.

Based “on the requirement for new leadership to guide the organization forward, as well as Blackmun’s serious health challenges, the board approved a separation agreement, as provided for in his contract,” Ms. Lyons said in the statement.
