FBI fires agent who failed to properly investigate USA Gymnastics doctor Larry Nassar

Washington — The FBI has fired an agent who failed to investigate allegations against former USA Gymnastics doctor Larry Nassar ahead of a congressional hearing centered on the agency's improper handling of the child sex-abuse investigation, sources familiar with the matter tell CBS News. 

FBI Director Christopher Wray, who rose to the position after the FBI's botched Nassar investigation, is slated to appear before the Senate Judiciary Committee on Wednesday to testify about the bureau's failure to pursue allegations against the former doctor, who has been sentenced to over 100 years in prison for sexual abuse and child pornography crimes.

The Washington Post first reported the agent's firing.
