The Justice Department’s inspector general’s report dissects the FBI’s failed response to allegations against the U.S. gymnastics team doctor in 2015

WASHINGTON—FBI agents disregarded allegations by Olympic gymnasts that they were sexually assaulted by former national team doctor Larry Nassar and later made false statements to cover their mistakes, Justice Department investigators said Wednesday in a long-awaited report on the bureau’s handling of one of the biggest abuse cases in U.S. sports history.

The Justice Department’s inspector general detailed multiple failings in the Federal Bureau of Investigation’s response to the gymnasts’ complaints, which were first brought into the Indianapolis field office on July 28, 2015, by USA Gymnastics, the sport’s national governing body. For more than a year after that, the bureau did almost nothing in response.
