D.C. Attorney General Irvin Nathan said Wednesday that prosecutors are unlikely to pursue current or former District employees who collected less than $20,000 in unemployment benefits while on the city’s payroll, meaning most of the 130 workers under investigation will probably avoid criminal sanctions.

“With respect to those that are the most egregious cases, we will definitely refer them to the U.S. attorney’s office for prosecution,” Nathan said. He later estimated the threshold for prosecution at $20,000, but said workers who stole less might still be targeted for criminal sanctions in some circumstances.
