The FBI is under fire after an internal watchdog report released yesterday found that the agency is continuing to mishandle child sex abuse cases.

It comes three years after the agency failed to investigate USA Gymnastics physician Larry Nassar.

In the new audit, the inspector general found that agents missed responding to 42 cases marked for “immediate attention.” That’s a staggering 12% of the cases he reviewed.

The auditors also noted a failure to report cases to local law enforcement and to follow FBI policies. They noted a lack of staffing, highlighted by one agent assigned simultaneously to 60 cases.

The FBI says it is learning from its mistakes and will implement the watchdog’s recommendations. However, lawmakers call the report “damning” and “outrageous.” Sen. Richard Blumenthal (D-Ct.) is calling for a hearing next month.
