Combining Huber (a prosecutor) with the Inspector General's office to investigate was a brilliant move:
…the inspector general’s jurisdiction to conduct civil and criminal investigations includes “actions taken by former employees after they have left government service.”
The Inspector General’s jurisdiction extends not only to allegations of legal violations, but also to allegations that Department employees violated established practices as well,” …which means that the IG’s report can hold people accountable even for actions that do not violate a specific statute.
“If a special counsel were appointed, there would be a great deal of delay,” Turley stated, versus the team of Huber and Horowitz, who are already five months into this investigation.
