Grassley demands answers why FBI agents weren't charged for lying about Nassar case

GOP Sen. Chuck Grassley sent a letter Wednesday to Attorney General Merrick Garland demanding to know why the Justice Department did not charge FBI agents who lied cover up their failure to investigate the abuse of female athletes by former USA gymnastics doctor Larry Nassar.

Grassley, the top Republican on the Senate Judiciary Committee, said he is "disappointed" with the department's lack of transparency on its response to the agents, one of whom was fired while the other resigned.

"When the department officials were asked by my colleagues to provide the physical evidence they evaluated to determine not to prosecute the agents, they declined," Grassley wrote.

"The declination came despite the case being closed. This is unacceptable, and I am again left wondering what the DOJ is attempting to restrict access to if they felt the evidence (or lack thereof) was not sufficient for prosecution."

The department announced in May it would not bring charges against the former FBI agents involved in the Nassar investigation.
