(36,063 posts)1) receipt of allegation/mandate to investigate
2) preliminary investigation, securing of sources of evidence
3) assessment of need to proceed, planning for investigation
4) execution of complete investigation
5) reporting
I don't think the above are formal categories but rather 'typical' phases that an investigation moves through.
It seems that 1 and 2, are completed and the investigation is proceeding. Providing immunity to Pagliano allows collection of evidence that can help frame inquiries and assessment of responses.
It seems as though the investigation has moved to 3 and perhaps back to 2 with the help of Pagliano, which will lead to planning in preparation of completing the investigation through questioning of Clinton and others who handeled information that ended up on the Clintons' server.
Sounds like step 4 is going to happen in the next few months with step 5 being reached in early summer.
