The Office of Inspector General said the Justice Department misreported terrorism statistics to Congress, the Associated Press reports.
The report, released Thursday, shows the Justice Department charged 544 people with terrorism-related crimes in the six years since the Sept. 11, attacks, not 512, as reported by the Justice Department, according to the AP.
In addition, 324 people were convicted or pleaded guilty to terrorism-related charges, not 319.
While the numbers were not significantly understated, the inspector general said such information must be reported accurately and more carefully, the AP reported.
